The two types of lawn aeration are liquid aeration and core aeration. Liquid aeration utilizes a liquid solution to penetrate and break up hardened soil, while core aeration requires specialized equipment to pull small portions of soil from the ground.

Both techniques are effective at improving the overall health of dehydrated, impacted soil and encouraging new grass growth. However, there are some differences between the two. Learning about the different types of aeration can help you determine the best course of action to take when rejuvenating your lawn. 

What Is Liquid Aeration?

Liquid aeration is a lawn care technique in which a specialized liquid solution is sprayed onto grass and soil. Once the solution works its way through the soil, it travels to the grass roots to increase oxygen levels and promote moisture penetration. When compared to core aeration, liquid aeration is less invasive and generally recommended for lightly impacted soil. 

Is Liquid Aeration Effective?

Liquid aeration is generally effective on soil that’s mildly impacted. The technique is noninvasive and not recommended for heavily impacted soil or heavy thatch. It’s also not a good option in high-drought areas. 

The Pros and Cons of Liquid Aeration

Liquid aeration is a helpful lawn care technique that safely loosens soil in a noninvasive fashion. The procedure is best suited for lawns with minor soil impaction issues and difficult-to-access roots, and it’s not usually recommended for severe soil impaction and drought-affected grass. Some pros and cons of liquid aeration include:

Pros

• Ideal for hard-to-reach areas. When liquid aerator solution is applied to soil, it’s capable of reaching hard-to-access areas, allowing for optimal water and nutrient absorption beneath the soil.
  
• Noninvasive. Liquid aeration solution is sprayed onto the soil with a hose or sprayer. This noninvasive technique makes liquid aeration a popular alternative to core aeration. 
• Cost-effective. Since liquid aeration is minimally invasive and doesn’t involve removing soil, it’s considered a cost-effective alternative to core aeration. 
• Better water absorption. Liquid aeration techniques break up lightly impacted soil, 

Cons

• Potential for ineffectiveness. In some cases, liquid aeration may be ineffective in soil conditions that are overly dry or overly wet.
  
• Slower results. Since liquid aeration must penetrate the soil, results may take longer than mechanical core aeration. 
• Doesn’t work well with heavily impacted soil. Liquid aeration isn’t recommended for heavily impacted soil, as the spray application may not be strong enough to penetrate the affected areas. 

What Is Core Aeration?

Core aeration is a lawn care procedure in which a specialized machine called a lawn aerator is used to create small holes in lawns and soil. The aerators are equipped with hollowed-out tines that pull “cores” from the ground. Core aeration is generally recommended for lawns with heavy thatch, impacted soil and/or moisture drainage problems. Removing the soil cores and breaking up the underlying soil creates a route for water and nutrients to safely reach the roots. 

Is Core Aeration Effective?

Core aeration is considered an effective solution for lawns with heavy soil compaction and drainage issues. The process involves removing small portions of compacted and/or dried soil and breaking up the remaining soil. When performed regularly, core aeration makes it easier for moisture and nutrients to enter the grass roots, allowing for a healthier lawn. 

The Pros and Cons of Core Aeration

Core aeration offers many benefits for lawns with impacted soil, heavy thatch and/or water drainage issues. However, there are some potential drawbacks to consider, and it may not be the best solution for every type of lawn. Here are some pros and cons of core aeration:

Pros

• Reduced thatch: Excess thatch can harm your lawn, suppressing nutrient and moisture absorption. Core aeration breaks up hardened, impacted soil, so nutrients and water can flow down to the roots.
• Enhanced germination: Core lawn aeration creates the ideal environment for seeds to germinate and develop into seedlings. The enhanced environment also makes overseeding safe. 
• Encourages a healthy, dense lawn: Core aeration treatments are specifically designed to break up compacted underlying soil. More balanced soil clears a path for fertilizers, water, air and essential nutrients to reach the root system. This encourages healthy grass growth and helps improve overall lawn density. 
• Minimizes the need for fertilizer: Core aeration procedures make it easier for your lawn to absorb and utilize fertilizer. Over time, this can help reduce the need for frequent fertilizing, allowing for easier maintenance. 

Cons

• Excess stress on the lawn. The digging involved in core aeration may lead to excess stress on the grass and underlying soil. If the procedure is performed aggressively or too often, recovery may be slow, 
• Unattractive lawn appearance. The holes and soil plugs that remain in and on your lawn after aeration treatment can create a temporarily unattractive appearance. 
• May increase the chance of weed growth. The holes left in your lawn sometimes create the perfect environment for weed growth. If you notice weeds in the core holes, address them right away.

Discolored grass is a sign there’s something wrong with your lawn care regimen. Lawn Doctor is here to help you understand what the different colors of grass mean, what color your grass should be and how to fix patchy lawn problems.

Dark Green Grass

Grass is green because of chlorophyll. A deep green lawn requires adequate nitrogen, the primary nutrient driving chlorophyll production, with iron and magnesium also playing secondary roles in enhancing color.

Hard fescue, perennial ryegrass and Kentucky bluegrass are all popular options for people who want an attractive, dark green lawn.

Light Green Grass

Some varieties of grass are naturally light green, even when they’re healthy. For other varieties, however, light green grass is a warning sign of poor irrigation. If your lawn is patchy with some areas dark green and others having a lighter appearance, it could be that the light green areas aren’t getting enough water, either because of the position of your sprinklers or because some areas are in the sun and are drying out more quickly.

Grassy weeds often appear lighter green and have a coarse texture that doesn’t blend well with turf. Most desirable lawn grasses are bred for uniform green color, so consistent light green usually points to irrigation or nutrient issues, not a specific lawn variety. If your lawn is shaded, you may find that some fescue varieties thrive in that environment and produce a light green color and a fine texture.

Bright Green Grass 

If you notice bright green or neon green colored patches on your lawn, this could be a warning sign that the pH of your soil is off, or that the soil is too wet. Both of these factors can cause your grass to take on an unusual color, as nutrients can’t flow properly when the soil is waterlogged.

Neon-green or lime-green patches may also be caused by weeds. Many weeds, including nutsedge, crabgrass, and goosegrass, appear lighter in color than desirable turf and often grow faster, creating uneven texture and appearance. These weeds are difficult to control once established and can quickly spread if not treated. It’s a very difficult weed to control, and can quickly become an eyesore if allowed to take hold in your lawn.

What Color Should Your Grass Be?

Healthy grass is green, although the shade of green may vary depending on the variety of grass you’ve planted. In general, a consistent, even green color across the whole lawn is a sign of a healthy garden. The shade may change over the course of the year, depending on the weather conditions and how much sunlight the lawn gets. If you need help with your lawn, consult a lawn care professional to get advice about how to care for it during each season.

What If Your Grass Is Different Shades of Green? 

Under ideal circumstances, your lawn should be a uniform color. Changes in the shade of your turf suggest there are differences in the environment. For example, if one area is starved of moisture or the soil isn’t well aerated, this can be reflected in the shade or color of the grass in that area.

Another thing people sometimes overlook is that there’s more than one type of grass. What you see as being a different color grass could be a different variety of grass taking hold on your lawn. If you’ve re-seeded your lawn with another type of grass, you might notice various patches of colors for a while.

To make sure your lawn has a uniform appearance, fertilize it evenly, aerate the soil at the right time of year and provide good drainage. If you’re not sure what type of fertilizer to use or you’re having other problems with the lawn, call in a lawn care professional for some expert advice.

But what exactly is cool season grass, and how can you make the most of it in your yard? In this article, we give you the lowdown on this versatile grass so you can grow the lushest lawn with confidence and know exactly what to expect throughout the year. 

What Is Cool Season Grass?

Cool season grass refers to turfgrass varieties that grow best in cooler climates, specifically in temperatures between 60 and 75 degrees Fahrenheit. These grasses enter their most active growing phases during the spring and fall, and they tend to slow down or go dormant during the heat of summer and the deep chill of winter.

Where Do Cool Season Grasses Grow?

Cool season grasses are most commonly found in the northern United States and the transitional zone, where summers aren’t overly intensely hot. These regions include the Northeast, Midwest, Pacific Northwest, and higher elevations in the central and western states.

If you live in an area with cold winters, mild springs and fall temperatures that dip gradually, your lawn is likely a good candidate for cool season grass seed.

Types of Cool Season Grasses

There’s no one-size-fits-all when it comes to cool season grasses. Several grass types fall into this category, each with unique features. Let’s take a closer look at five of the most common varieties.

Kentucky Bluegrass

Kentucky bluegrass is one of the most popular choices thanks to its lush, dense growth and striking color. This grass spreads via underground rhizomes, making it excellent for self-repair. It performs best in full sun but can tolerate some shade.

Tall Fescue

Known for its heat and drought tolerance, tall fescue is a robust option with deep roots that make it more resilient during dry periods. Tall fescue has a coarser texture than some other cool season grasses, but it’s a favorite with homeowners looking for durability and easy maintenance.

Fine Fescue

Fine fescues, including creeping red, chewings and hard fescue, are excellent for shady areas. They grow well in poor soils and are often mixed with other grass types to balance sun and shade needs. 

Ryegrass

Perennial ryegrass is known for its rapid germination and bright green color. It’s often used for overseeding because it gets established quickly, making it ideal for patch repairs and temporary cover. While it doesn’t spread like Kentucky bluegrass, it forms a thick mat when properly maintained.

Orchard Grass

Though often used in pastures, orchard grass can also be part of cool season lawn mixes. Though it’s less common in traditional home lawns, it’s still considered part of the cool season family and can contribute to a lawn blend in specific scenarios.

When Do Cool Season Grasses Go Dormant?

Cool season grasses are most active in spring and fall. But when do these grasses go dormant? Typically, they slow their growth or enter dormancy when temperatures climb above 85 degrees Fahrenheit. During summer, you may notice browning or thinning, which is the grass’s natural way of conserving energy and moisture.

Dormancy may also occur in the coldest winter months, especially in regions with heavy frosts and snow. But don’t worry, your lawn will bounce back once temperatures creep back up again. 

How Do You Maintain Cool Season Grass?

Keeping cool season grass looking its best requires a seasonal maintenance strategy. Performing the following maintenance tasks at the recommended times can help you keep your lawn healthy year-round.

Fertilize

Cool season grasses should be fertilized primarily in the fall and spring when growth is most active. Fall fertilization is particularly important, as it helps build strong roots and prepares the lawn for winter dormancy.

• Apply a nitrogen-rich fertilizer in early fall
• Follow up with a winterizing fertilizer before the first frost
• Apply a lighter dose in spring once growth resumes

Avoid fertilizing in the peak of summer, as the grass is already under stress and may not absorb nutrients effectively.

Aerate

Aeration involves removing small plugs of soil to reduce compaction and improve airflow, water absorption and nutrient uptake. So, when to aerate cool season grass? The best time is early fall, although aerating in spring is also acceptable.

• Aerate once a year if your soil is compacted
• Focus on high-traffic areas that show signs of wear
• Combine aeration with overseeding for best results

Overseed

Overseeding helps fill in bare spots, boost density, and improve your lawn’s resilience. Early fall is the ideal time for overseeding, as the soil is still warm from summer and rainfall is more frequent. Spring is your second-best option, but it comes with the risk of summer stress.

When applying cool season grass seed:

• Choose a variety that matches your existing lawn
• Mow the lawn short before overseeding
• Use a spreader for even coverage
• Water consistently until new grass is established

Is Bermuda a Cool Season Grass?

While many grasses fall into the cool season category, there are some exceptions. Bermuda grass, for example, is a warm season grass. It thrives in hot southern climates and going dormant when temperatures fall below 60 degrees Fahrenheit. It’s important to understand this distinction when selecting or blending seed varieties.

What Is Cool Season Grass Seed?

Cool season grass seed includes varieties like Kentucky bluegrass, fescue, and ryegrass. These blends are formulated to perform well in cooler regions, with each type contributing specific benefits such as shade tolerance, fast germination or heat resistance.

When choosing a grass seed, consider:

• Your region and climate
• Sun and shade levels
• Traffic levels and lawn use
• Maintenance preferences

In this guide, we’ll walk you through everything you need to know, from identifying common types of warm season grasses to understanding how and when to fertilize, aerate and overseed your lawn.

What Is Warm Season Grass?

Warm season grass refers to grass varieties that grow best in temperatures between 80 and 95 degrees Fahrenheit. These grasses begin growing in late spring, hit their peak during the heat of summer, then slow down and go dormant as temperatures cool in the fall.

Where Do Warm Season Grasses Grow?

Warm season grasses are most common in the southern United States, particularly in areas such as the Southeast, Gulf Coast, Southwest and lower portions of the transition zone. They love full sun, tolerate drought and perform well in sandy or clay-heavy soils.

Types of Warm Season Grasses

Warm season grasses come in a variety of textures and colors and with different maintenance needs. Here are five of the most popular options you’ll come across.

Bermuda Grass

Bermuda grass is one of the most commonly used grasses in the South. This grass grows quickly, spreads aggressively and stands up to heavy use, which makes it a favorite for sports fields and high-traffic lawns. It loves full sun and doesn’t perform well in shade.

Zoysia Grass

Zoysia is known for its dense growth and soft texture, making it a popular choice for homeowners seeking a manicured look. It’s more shade-tolerant than Bermuda grass and handles foot traffic well. Once established, it’s relatively low maintenance.

Centipede Grass

Centipede is sometimes called the “lazy man’s grass” because it grows slowly and needs minimal care. It has a light green color and prefers acidic soil. While it’s not great for high-traffic areas, it’s a solid choice for a low-maintenance lawn in warm climates.

St. Augustine Grass

St. Augustine is a warm-season favorite in coastal areas. It has broad, coarse blades and a rich green color. St. Augustine handles heat and humidity well and grows in a thick mat that helps crowd out weeds. However, it’s more susceptible to pests and diseases than other warm season grasses.

Bahiagrass

If you’re dealing with poor soil and dry conditions, planting bahiagrass might be the answer. It’s often used in pastures and along roadsides, but it also works as a lawn grass in some southern areas. Bahiagrass doesn’t require a lot of fertilizer or water, but it can look rough due to its coarse texture and tall seed heads.

When Do Warm Season Grasses Go Dormant?

Warm season grasses begin to go dormant as soil temperatures fall below 55 degrees Fahrenheit. This usually happens in mid-to-late fall depending on your region. During dormancy, the grass turns brown and stops growing. However, it’s not dead but simply conserving energy until warmer weather returns.

How Do You Maintain Warm Season Grass?

Caring for warm season grass involves timely mowing and watering, and completing seasonal tasks such as fertilizing, aerating and overseeding. Here’s a breakdown of how and when to care for your lawn.

Fertilizing

Warm season grasses benefit from fertilization during their active growth period. Here’s when to fertilize warm season grasses for the best results:

• Apply the first feeding in late spring, once the lawn has fully greened up
• Continue fertilizing every 6 to 8 weeks throughout the summer
• Stop feeding in late summer to avoid pushing growth as the lawn heads into dormancy

Aerating

Soil compaction can be a problem, especially in lawns that get a lot of use. Aerating helps relieve compaction, improves water and nutrient flow and encourages deeper roots. So when to aerate warm season grass?

• Late spring or early summer is best, once the lawn is actively growing
• Aerate every 1–3 years depending on soil conditions and traffic levels

Overseeding

Overseeding helps thicken your lawn and fill in bare spots, but it can be tricky with warm season varieties since they spread more through runners than seed. Still, overseeding with warm season grass seed can be useful when establishing new areas or reinforcing older turf.

• Overseed in late spring to early summer when temperatures are consistently warm
• Use seed that matches your existing lawn for a uniform look

What Warm Season Grass Grows in the Shade?

Most warm season grasses prefer full sun, but some varieties perform better in partial shade. Zoysia and St. Augustine are the best options if your lawn has shady areas. They tolerate filtered sunlight better than Bermuda or centipede, however, no warm season grass thrives in dense shade.

Is Fescue or Kentucky Bluegrass a Warm Season Grass?

You might be wondering about some commonly used grasses. Is fescue a warm season grass? No. Fescue, including tall fescue, is considered a cool season grass. The same goes for Kentucky bluegrass. These grasses do best in cooler climates and typically don’t hold up well in prolonged summer heat, which is why they’re not suited for the southern United States.

What Is Warm Season Grass Seed?

Warm season grass seed includes varieties such as Bermuda, zoysia, bahiagrass and centipede. Each has its strengths and is suited to different soil and sunlight conditions. Choosing the best warm season grass for your lawn depends on your location, lawn use and the level of care you’re willing to commit to.

Let’s take a closer look at how to identify this hardy turfgrass, understand its pros and cons and learn what to do if it pops up where you don’t want it.

What Is Bahia Grass?

Bahia grass (Paspalum notatum) is a warm-season turfgrass commonly used in the southeastern U.S. Known for its durability and tolerance to drought, bahia grass is often used in lawns, pastures and along roadsides where other grasses may struggle to grow.

So, is bahia grass good for lawns? The answer depends on what you’re looking for. If you need a grass that can handle poor soil, full sun and minimal watering, then yes, a bahia grass lawn could be a great fit. However, if you prefer a lush, fine-textured lawn with deep green color, you might find bahia’s appearance a bit coarse.

Varieties of Bahia Grass

Not all bahia grass is the same. Several cultivated varieties exist, each with unique characteristics. Here are the most common ones you may come across.

Argentine Bahia Grass

Argentine bahia grass is a popular choice for home lawns because of its attractive, darker green color and relatively uniform texture. It produces fewer seed heads compared to other varieties, which helps maintain a cleaner lawn appearance. It grows well in sandy soil and performs best with regular mowing and maintenance.

Pensacola Bahia Grass

Pensacola bahia grass is more cold-tolerant than Argentine and is often used in the northern parts of the warm-season zone. It has narrower blades and produces more seed heads, which can be a drawback for some homeowners. However, it grows aggressively and is excellent for erosion control and rougher turf areas.

Other Varieties

Other cultivars, such as Tifton 9 and UF Riata, are developed primarily for pasture use but may occasionally show up in turf mixes. These are less common for home lawns but worth knowing in case you’re dealing with mixed seed or sod.

Pensacola Bahia Grass

Other Varieties

Other cultivars, such as Tifton 9 and UF Riata, are developed primarily for pasture use but may occasionally show up in turf mixes. These are less common for home lawns but worth knowing if you’re dealing with mixed seed or sod.

Bahia Grass as Lawn

A bahia grass lawn is low-maintenance, drought-tolerant and tough enough to handle heavy foot traffic and full sun. Its deep roots make it well-suited to sandy soils, and it doesn’t require frequent watering or fertilizing to survive.

However, appearance-wise, bahia grass can be more rugged. It tends to grow tall seed heads quickly, which can give a lawn a weedy look if not mowed regularly. Some homeowners appreciate its resilience, while others prefer a more manicured turf.

Is Bahia Grass a Cool or Warm-Season Grass?

Bahia grass is a warm-season grass. That means it grows best in the heat of late spring through summer and slows down or goes dormant when temperatures cool in fall and winter.

If you’re wondering, “Is bahia grass a cool or warm season grass?” the answer is clear. It thrives in warmer climates and is commonly found in states like Florida, Georgia, Alabama and parts of Texas and the Carolinas.

When Does Bahia Grass Grow?

Bahia grass begins growing when soil temperatures reach around 65°F, which usually happens in mid to late spring depending on your region. Growth peaks during the summer months, then tapers off as cooler fall temperatures arrive.

Because it’s a warm season grass, bahia grass won’t green up early in the year. It typically remains dormant through winter and may appear brown or patchy until warm weather returns.

How to Care for a Bahia Grass Lawn

Bahia grass maintenance is simple, but a few key practices will help you keep your lawn healthy and looking its best.

Mowing

• Keep your bahia grass lawn mowed to 2.5 to 4 inches
• Mow regularly to prevent seed heads from forming and creating a weedy appearance

Watering

• Water deeply but infrequently
• Bahia grass is drought-tolerant, but during extended dry spells, supplemental watering will help maintain color and vigor

Fertilizing

• Apply a balanced fertilizer in late spring once the grass is actively growing
• A second light feeding in midsummer may be beneficial
• Avoid over-fertilizing, as bahia is sensitive to high nitrogen levels

Weed Control

• Keep an eye out for common weeds in bahia grass, such as crabgrass, spurge and dollarweed
• Maintaining a thick lawn and proper mowing height helps prevent weed invasion

Aeration

• Aerate annually if your soil is compacted or if your lawn sees heavy foot traffic

Bahia Grass as a Weed

While bahia grass has many benefits, it’s not always welcome in every yard. Its coarse texture, fast-growing seed heads and aggressive spread can make it undesirable in finely manicured lawns or in areas where it wasn’t intentionally planted.

If you’re wondering why bahia grass is growing in your cool season lawn, the likely culprit is contaminated seed or encroachment from nearby roadside or pasture grass. Once established, it can be tricky to remove without damaging your desired turf.

How to Kill Bahia Grass Without Damaging Your Lawn

Controlling unwanted bahia grass requires a targeted approach, especially if you’re trying to protect surrounding turf.

Here’s how to remove bahia grass while minimizing harm to the rest of your lawn.

Spot Treatment

• Use a selective herbicide designed to kill bahia grass without harming your primary turf
• Apply directly to unwanted patches following the label instructions

Manual Removal

• For small infestations, dig out the clumps, roots and all
• Dispose of the removed material to prevent reseeding

Lawn Renovation

• In severe cases, it may be necessary to kill and reseed affected sections
• Use proper seed and maintenance practices to prevent bahia from returning

Ongoing Maintenance

• Mow regularly to prevent seed formation
• Keep your lawn healthy and thick to discourage bahia grass weeds from taking hold

It’s important to know that some herbicides may require multiple applications or may not work well in extreme heat. If you’re unsure, your local Lawn Doctor professional can recommend the best plan for controlling bahia grass weeds in your region.

What Is Dethatching?

Dethatching involves removing the layers of dead leaves, grass clippings and other organic matter that builds up between fresh grass blades and underlying soil. Dethatching is necessary, as heavy thatch build-up can hinder the flow of water, air and other essential nutrients.

If thatch isn’t removed on a regular basis, it can increase the risk of damage to both the visible grass and its underlying soil and roots. The tools and equipment used for dethatching include electric rakes, specialized thatch rakes, power rakes, hoes and durable leaf rakes. 

The Benefits of Dethatching

Periodic dethatching helps improve lawn health while making it more visually appealing. Some additional benefits of dethatching include:

• Improved water and nutrient flow: Excessive thatch can create a barrier between the soil and necessary water and nutrients. Removing the thatch can help improve overall water and nutrient flow, allowing for strong, healthy roots and soil. 
• Reduced risk of mold growth and other diseases: Certain types of organic matter in thatch layers may carry harmful pathogens such as mold spores and other types of fungi. Dethatching can significantly reduce the risk of diseases. 

What Is Aeration?

Aeration is the process of creating holes in tight, impacted soil to allow water, nutrients and air to flow easier toward the roots. When soil is impacted, it makes it difficult for essential nutrients and moisture to properly fertilize the underlying grass roots. Over time, impacted soil can lead to a host of issues, ranging from discolored grass to damaged roots. 

The two types of aeration are liquid aeration and core aeration. Liquid aeration is a minimally invasive procedure when a liquid solution is applied directly to the affected soil. The solution is designed to gently separate the impacted soil to allow for improved water, nutrient and air flow. 

Core aeration is an aeration technique in which specialized equipment is used to pull small plugs from the soil. This process creates indentations in the soil that allow for improved water and nutrient saturation, stronger root growth and lush grass. 

The Benefits of Aeration

Both liquid and core aeration procedures offer a wide range of benefits. If your yard contains hardened soil that’s difficult to break down or penetrate, it can lead to issues such as dead grass, yellow and brown patches, hindered plant root growth and drainage issues. Some benefits of lawn aeration include:

• Reduced soil compaction: Both core aeration and liquid aeration help eliminate impacted soil. Core aeration works well with severely impacted soil, while liquid aeration is best suited for minor soil impaction. 
• Improved water drainage: Aeration procedures help improve water drainage by breaking up the impacted soil. 
• Root stimulation: Aeration breaks up hard, impacted soil and creates a pathway for hydration and nutrients to penetrate the root system. This helps encourage root stimulation and healthy plant growth. 
• Stronger root systems: Aeration makes it easier for moisture and nutrients to reach the grass roots. When the roots are stronger, they’re better at withstanding extended hot and dry periods. 
• Improved maintenance: When your lawn and its underlying soil are healthy and hydrated, it makes it much easier to maintain. Strong, lush grass tends to be more resistant to weed growth, and it should also recover faster from pest invasions and lawn diseases. 
• More resistance to pest infestations: A thriving root and soil system and healthy lawn are naturally equipped to fend off pests and other invaders when compared to weakened roots and soil damage.

Can You Aerate and Dethatch at the Same Time?

It is possible to aerate and dethatch your lawn at the same time. However, it’s recommended to dethatch your lawn first and follow up with aeration. Since dethatching consists of removing dead organic matter such as grass clippings, roots and dried leaves, it should always take place first. This helps ensure a clean starting point for liquid or core aeration and reduce the risk of lawn damage. 

Dethatching and aeration are essential procedures that help ensure your lawn remains healthy and thriving. Lawn Doctor has provided quality lawn care solutions for over 5 decades, and we have locations in 40 U.S. states and Puerto Rico.

Drought-Tolerant Grasses for Cool Climates

Tall Fescue

This resilient and adaptable grass has a coarse texture and requires heavy seeding, but once seeded, it copes well with only a limited amount of water and happens to be capable of tolerating a lot of foot traffic, making it a good option for busy gardens.

Sheep Fescue

If you prefer a more natural appearance to your yard, sheep fescue is a good option. This bunching grass requires fertilizing once every 2 years and doesn’t require mowing frequently. However, it has an uneven texture and isn’t a good option for a lawn that will be used for play or relaxation.

Kentucky Bluegrass

Compared to the other grasses listed above, Kentucky bluegrass requires more water. However, if the soil is fertile and the grass isn’t mowed too short, it can survive on half of its usual water intake. It’s also quite resilient to foot traffic. If you live in an area where it’s only dry for a few months of the year, this grass could be a suitable (and visually appealing) option.

Even drought-tolerant grasses will require some water, but the deep root systems of many of these varieties mean they can collect water from the soil quite effectively, taking advantage of even the most brief rainy spell. In general, however, most of the grass varieties listed above will benefit from watering once a week.

Drought-Tolerant Grasses for Warm Climates

Bermudagrass

A fast-healing grass that has a deep root system, bermudagrass is quite resilient and recovers quickly after dry spells. This grass goes dormant during the winter months, so many lawn owners overseed it with another variety, such as ryegrass, to keep a nice green-looking lawn year-round.

Buffalograss

Buffalograss has a thick, lush turf and is quite a hardy type of grass. Ideally, it requires only 1/4 inch of water a week during the summer months, but it can survive on even less water than that for a while. Buffalograss thrives best when left unmowed and grows to around 5 inches, making it ideal as a decorative grass but less suited to backyard gardens.

St. Augustine Grass

This coarse-leaf grass does best in shaded areas and is reasonably resilient, so it can handle some foot traffic. It goes dormant during the winter but retains a medium-green appearance when it does so. It’s a drought-resistant variety and can actually become susceptible to diseases if it’s overwatered.

Warm-season grasses grow best during the summer months and usually cope better with dry spells than their cool-season counterparts. However, it’s still important to check that the specific variety you choose has been cultivated with drought resistance in mind.

How to Care for Your Lawn During a Drought 

Lawns that are generally in good health are more likely to survive a drought than ones that are already struggling. If you want to make sure your lawn is prepared for dry weather, get into the habit of watering it deeply but infrequently. In addition, make sure the soil is properly aerated and fertilized with the right fertilizer and to an appropriate schedule.

Mowing practices can make a big difference to lawn health. Taking care to mow to the right length for the type of grass is essential. Cutting too short can make the grass more susceptible to damage.

If you’re in the middle of a drought and are rationing water, wait until later in the day when it’s cooler to water your lawn so that the water doesn’t just evaporate, and try not to cut the grass too often.

Keep in mind that your grass may turn yellow during a drought. This is a sign that it’s gone dormant to try to survive the drought. Dormant grass isn’t dead and should recover once it starts receiving water again. However, dormant grass is more susceptible to damage, so try not to disturb it too much by letting pets or children play on the lawn.

Types of Ants

Different environments have different ant species. Understanding the specific ant species in your yard and what’s attracting them is the first step toward effective control measures. Different types of ants exhibit unique behaviors, nesting habits and food preferences, which influence the most suitable treatment strategies. Common yard ants include:

• Fire ants. Known for their painful stings and aggressive behavior, these ants are typically reddish-brown and create mounds in sunny areas. Fire ants are particularly problematic because their bite is painful, and they spread quickly.
• Carpenter ants. Often black or dark brown and larger than most ants, these ants can damage wooden structures. Carpenter ants are a concern for homeowners as they can weaken wood over time, leading to structural issues.
• Pavement ants. Typically found nesting in cracks or under stones, these ants are dark brown to black and create small mounds. Pavement ants are common in urban areas and can be difficult to eradicate due to their nesting habits.
• Garden ants. As their name suggests, these often harmless ants are common in gardens. Usually black or brown, they can disrupt soil around plants. While garden ants generally aren’t destructive, they can still be a nuisance by creating small mounds and trails.

Identifying the species helps determine the best removal strategy, as some ants may require targeted approaches, such as baiting or physical barriers.

What Attracts Ants to Your Yard?

Ants are drawn to yards for several reasons, including food sources, moisture availability and the type of shelter they like.

• Food sources. Leftover food, pet bowls or sugary substances, such as those found in hummingbird feeders, attract ants. Regularly cleaning up food waste and sealing pet food containers can help reduce ant activity. 
• Moisture. Standing water or damp soil provides hydration for ants. Fixing leaks and improving drainage can reduce moisture levels. 
• Shelter. Areas such as mulch beds, woodpiles or cracks in pavement offer nesting spots. Consider using ant-repellent mulch or sealing cracks in the pavement.

What Harm or Damage Can Ants Cause?

While some ants are beneficial for aerating soil, others can cause problems. Certain ants attract aphids that harm plants by sucking sap and spreading disease. This can lead to weakened plants that are more susceptible to other pests and diseases.

The stings of fire ants and other biting species can cause painful welts and even allergic reactions.

Carpenter ants can weaken wooden structures over time by excavating tunnels for nesting. They may nest in wood piles or inside stored non-wooden objects, such as covered deck chairs.

How to Get Rid of Ants

To get rid of ants outdoors, you can try several strategies.

Try Natural Remedies

First, use some natural remedies.

• Pour boiling water into ant mounds. This method kills many ants instantly but may harm surrounding vegetation. It’s best for isolated mounds and should be used cautiously to avoid damaging plants.
• Sprinkle food-grade diatomaceous earth around anthills and trails. Doing this dehydrates ants, effectively killing them without harming plants. DE is a generally safe, nontoxic option for pet owners and gardeners.
• Mix equal parts vinegar and water, and spray it on ant trails or mounds. This disrupts ants’ pheromone paths, making it difficult for them to navigate. Vinegar is a natural, environmentally friendly option.

Place DIY Ant Baits

Create baits using borax mixed with sugar or honey. The sweet substance attracts ants, while borax kills them when ingested. Place these baits near ant trails but out of reach of pets and children. 

Create Physical Barriers

Create a barrier using cinnamon or orange oil around areas you want to protect. Sprinkle cinnamon powder or apply orange oil to entry points to prevent ants from crossing.

Flood Nests

Use a garden hose to flood ant nests with water. This method is less harmful to plants than boiling water but may require repetition to fully eliminate the colony. 

Apply Professional Products

Ant bait granules or insecticides designed for outdoor use can eliminate entire colonies when applied correctly. Always follow product instructions to ensure safety and effectiveness. These products are often potent and should be used with caution around pets and children.

How to Prevent Ants From Coming Back

Prevention is key to maintaining an ant-free yard. 

• Remove attractants. Keep food waste sealed and away from the yard. Relocate compost bins and trash cans away from high-traffic areas.
• Maintain your lawn. Mow grass regularly, and avoid bare patches. Remove plant debris, such as fallen branches and leaves. 
• Seal entry points. Fill cracks in pavement or foundations where ants might nest.
• Conduct regular inspections. Regularly inspect your yard for signs of ants, such as mounds or trails, and address them promptly.
• Introduce beneficial insects. Beneficial insects, such as ladybugs or lacewings, prey on ants. These insects can help control ant populations naturally.
• Add ant-repellent plants. Planting ant-repellent herbs, such as mint or basil, around the perimeter of your yard can help deter ants. These plants release oils that ants don’t like.
• Apply natural mulch: Use natural mulch that repels ants, such as cedar chips, around plants. Cedar mulch is a safe and effective way to deter ants from nesting near plants.

By identifying the type of ants, understanding what attracts them and using natural or professional remedies, you can figure out how to get rid of ants outdoors and reclaim your yard as a safe and pleasant haven!

What Are Armyworms?

Armyworms are moths in their larval stage. They earn their name based on the way they move across your lawn like an army and eat all the grass blades in their way. Southeastern states tend to sustain the most damage from armyworms, but these pests are found in all states east of the Rocky Mountains. There are different varieties of armyworms, including fall, yellow-striped, beet and true armyworms. In many areas, it’s the fall armyworms that most commonly destroy grass blades. 

How to Identify Armyworms

Armyworms are active later in the evening and into the night, so you probably won’t catch a glimpse of them during the day. They can range in color from black to greenish-brown with a smaller yellowish-brown head and stripes along the abdomen that are orange, white or brown. However, the coloring may vary based on the type you have. For instance, true armyworms are typically tan while fall armyworms appear gray. The pests are about 1-1/2 inches long when fully grown.

You might be more likely to identify the problem by the damage they leave behind. It often starts as a small brown patch that grows quickly. 

What Attracts Armyworms to Your Lawn?

The grass that covers your yard is the main feature that attracts armyworms. The adult moths lay their eggs near food sources, which include turfgrass. Armyworms aren’t picky — they eat most types of grasses as well as crops and fruit trees.  

However, they may be more likely to choose yards with long grass, lots of weeds or lawn debris. Those features serve as protection from natural predators for the eggs and larvae. Wet conditions may appeal to armyworms, so be cautious if drainage issues keep your yard damp. 

What Damage Can Armyworms Cause?

Damage from armyworms often becomes noticeable later in the summer. In the beginning, it might look like drought damage. When armyworms are in the lawn, the grass tends to change colors and may lie flat. If you look closely, you might notice that the tips of the grass blades are chewed or that the edges look ragged. 

It doesn’t take long for armyworms to complete their destruction, especially if you have a major infestation. They can destroy an entire lawn in just a few days. The grass turns brown, and you could end up with dirt patches in your lawn. 

How to Get Rid of Armyworms in Your Lawn

Insecticides are often the fastest and easiest way to get an armyworm infestation under control. Products that typically work include those containing ingredients such as bifenthrin, permethrin and cypermethrin. You may be able to use Bacillus thuringiensis for a more natural treatment for armyworms if you catch the infestation early. It only works on younger caterpillars, so it won’t kill full-grown armyworms in your yard. 

Leaving the pesticide application to the professionals often gives you better results. Pest control companies can use commercial-grade chemicals that aren’t available to homeowners. At Lawn Doctor, we know when and how to treat armyworms properly. 

How to Prevent Armyworms

Eliminating the areas in your lawn that are attractive spots for moths to lay their eggs could help prevent an armyworm infestation. Keep your lawn mowed regularly, and clean up any lawn debris. If you haven’t dethatched your lawn in a while, doing so could help with armyworm prevention by removing the debris that shelters the caterpillars. Getting weeds under control may help. If you have wet areas in your yard, consider ways to improve drainage. 

Natural predators of armyworms can also help keep populations under control. Ladybugs and lacewings are helpful insects that you can purchase and add to your garden. They eat the eggs, keeping armyworms from emerging. Parasitic wasps are also ideal for natural pest control since they eat many types of garden pests, including armyworms, but they’re not harmful to humans. Attracting birds to your yard is helpful since they eat armyworms at all stages as well as other pests that could damage your lawn. 

Keep an eye on your lawn regularly to look for early signs of an infestation before large numbers of armyworms take over. The adults typically lay larger clusters of eggs together, so you can check plant bases and the undersides of leaves for clumps of eggs. A quickly growing brown area in your yard could also indicate a problem. 

At the first sign of an infestation of armyworms in your yard, call Lawn Doctor for treatment options. Our pest control solutions protect your yard from armyworms and many other pests to keep your grass looking pristine. Contact us today to learn more about how we can help.  

What Are Billbugs?

Billbugs are turf-feeding insects that belong to the weevil or snout-beetle family. Adult billbugs range from 0.25 to 0.5 inches long and may be gray, black or brown. They have wings but rarely fly, instead crawling significant distances. Species have slight physical variations, but they’re generally recognizable by their distinctively curved bills or beaks.

Billbug species have an annual life cycle during which they produce one generation. Understanding the life cycle phases provides insight into the ideal billbug treatment and prevention measures:

• Egg stage. Adults lay eggs inside grass stems in the spring.
• Larva stage. The larvae (white and legless grubs) hatch and feed on grass crowns and roots as they tunnel downward.
• Pupa stage. The larvae pupate in the soil after several weeks of feeding.
• Adult stage. Adults become active in the spring, laying eggs and restarting the cycle.

Different Types of Billbugs

While billbug species share many traits, certain types dominate, depending on the area and its climate. Each species follows a similar life cycle, but regional differences in climate and turfgrass influence their behavior, timing and preferred habitat.

Bluegrass Billbug

This species is most common in northern climates and favors Kentucky bluegrass. Adults are often light brown and emerge in spring when temperatures increase.

Hunting Billbug

More prevalent in the southeastern United States and other warm regions, hunting billbugs prefer warm-season grasses, such as zoysia and Bermuda. Adults are darker and more active at night.

Phoenix Billbug

Native to desert regions, Phoenix billbugs feed on turf types adapted to arid environments. Activity peaks during the cooler seasons in the Southwest.

Rocky Mountain Billbug

This species is more common in high-elevation and cool-climate areas and prefers fescues and other cool-season grasses.

What Causes Billbug Infestations?

Certain factors increase the risk of billbug infestations by creating ideal conditions for adults and larvae to thrive. Some conditions are unavoidable, such as warmer spring temperatures that signal the life cycle’s restart.

Dense thatch layers protect larvae and encourage them to thrive. Stressed lawns may result in weaker root systems that are more vulnerable to billbug larvae damage, likewise providing easier access to food and creating ideal survival conditions. Poor lawn care practices that contribute to lawn stress include:

• Overwatering
• Drought
• Poor drainage
• Soil compaction
• Insufficient soil nutrients

Signs of a Billbug Infestation

Symptoms of billbug infestations often mimic other turf issues and make them easy to miss. Identifying the signs promptly and accurately allows you to take action sooner and minimize billbug lawn damage.

Yellow or Thinning Turf

In the early stages of billbug infestations, affected turf may appear yellow, brown or thin, resembling damage from heat or drought stress. Unlike drought-damaged turf, however, billbug-affected turf often comes out easily when tugged on since the damage results from larval feeding in the roots.

Chewed Grass

Adult billbugs feed on grass blades during the spring and early summer, leaving behind small notches or chewed edges in the soil. A cutting of grass may reveal a hollow or chewed stem or sometimes larvae inside the crown and stem tissue.

Frass

Turf inspection may also show larvae excrement, also called frass, which looks like sawdust. Larvae leave frass inside grass stems and in thatch layers.

Adult Billbug Sightings

In spring and fall, adult billbugs may appear crawling across sidewalks or driveways.

What Damage Can Billbugs Cause?

Billbugs affect turf above and below toil, with the severity of damage depending on the population size and the lawn’s overall health.

Aesthetic Impact

Billbug feeding creates patchy areas of brown or yellow turf that may disrupt the lawn’s appearance and expand if larvae continue feeding. Turfgrass may fail to recover if larvae have damaged roots beyond repair.

Long-Term Health Issues

Root damage interferes with the turf’s ability to absorb water and nutrients, gradually weakening it and increasing susceptibility to weeds, disease and other pests. Weakened turf also has more difficulty recovering from foot traffic, drought and other environmental challenges.

Lawn Restoration Costs

Severe infestations may require lawn restoration with overseeding and partial to full sod replacement. Additional treatments, such as aeration and fertilization, may also be necessary to restore lawn health and resilience. Depending on the size of the affected area, this can be a time-consuming and costly process.

How to Get Rid of Billbugs

Billbug control involves a combination of targeting methods and timing to maximize the effects.

Biological Controls

Beneficial nematodes are microscopic roundworms that prey on billbug larvae and other soil-dwelling insects, often yielding noticeable results within a few days. These are best applied after the adults lay eggs and during peak larvae activity. Products containing certain kinds of fungus or milky spore also eliminate adult and larval billbugs.

Chemical Controls

Chemical controls are effective as targeted treatments and preventative measures. Preventative insecticides contain imidacloprid, bifenthrin and other active ingredients that function as systemic treatments. They absorb into the plant and affect larvae that feed on stems and roots without impacting the plant itself. Other kinds of insecticides target adult billbugs to prevent them from laying another generation of eggs.

How to Prevent Billbugs

Healthy lawns are naturally pest-resistant, and preventative measures often function as a way to combat current infestations and prevent recurrences. Try these preventative strategies:

• Plant billbug-resistant and endophyte-enhanced turfgrass, such as perennial ryegrass and tall fescue.
• Inspect your lawn regularly for signs of pest damage in the spring and summer.
• Follow lawn health best practices, such as proper mowing, watering, fertilization and aeration.
• Ask your lawn care expert about applying preventative treatments, such as beneficial bugs and insecticides.
