Effective Strategies for Getting Rid of Crabgrass in Summer – Lawn Care Tips

how to get rid of crabgrass

Summer is often seen as the season of joy and happiness. It’s the time when we start planning trips, family reunions, and much-needed vacations. But for some of us, the ideal summer day is not spent traveling but right at home, tending to our gardens. Yes, you read that correctly. Gardening.

Why not spend your precious summertime soaking up the sun, boosting your vitamin D levels, and taking care of your lawn and garden? Those who have a passion for gardening will surely understand the satisfaction of seeing a well-maintained and thriving garden under the summer sun. This is also the perfect time to tackle those pesky weeds that seem to spring back to life during this season. The top offender on most gardeners’ lists? Crabgrass.

What is Crabgrass?

Crabgrass, often mistaken for regular grass, is a common weed that tends to invade lawns during the summer months. Its stems grow low to the ground and spread out in a pattern reminiscent of crab legs – hence the name. This opportunistic weed thrives in hot, dry conditions and takes root in thin and bare spots in the lawn. It produces thousands of seeds, making it a persistent problem if it is not addressed promptly.

Crabgrass is considered a nuisance because it competes with desirable grass types for nutrients, water, and sunlight, hindering the growth of a healthy, lush lawn. Moreover, its unsightly appearance can detract from the overall aesthetic of your garden.

While crabgrass dies off naturally as temperatures drop in late fall or early winter, it leaves behind thousands of seeds ready to germinate the following spring. So, if you want to win the battle against this resilient weed, you will need a strategic plan of action.

Top 10 Strategies for Effective Crabgrass Control in Your Lawn

Each of these tips can effectively help in controlling crabgrass on your lawn:

Identify the Crabgrass

This is important because different weeds require different control methods. Crabgrass has a distinctive look; it grows low and spreads outward in a star shape with wide, light green blades. By accurately identifying it, you can apply the most effective treatment.

Water Your Lawn Properly

Overwatering or underwatering your lawn can make it vulnerable to crabgrass invasion. Deep, infrequent watering encourages the growth of desirable grasses with deep roots that can outcompete crabgrass.

Fertilize Your Lawn

A well-fertilized lawn will have strong, healthy grass that can crowd out crabgrass. Regular applications of a balanced fertilizer can keep your lawn robust and less hospitable to crabgrass.

Spray Pre-emergent Herbicide

Pre-emergent herbicides form a chemical barrier in the soil that prevents crabgrass seeds from sprouting. Timing is key; it should be applied in the spring before the crabgrass begins to grow.

Reseed Bare Lawn Areas

Crabgrass loves bare patches of soil. By promptly reseeding bare areas with desirable grass seed, you’ll leave less room for crabgrass to establish itself.

Hand Pulling

For small crabgrass infestations, pulling up the plants by hand can be effective. It’s easier when the soil is moist, and it’s important to remove the whole plant, roots and all, to prevent it from growing back.

Solarize Your Soil

Solarizing your soil is a great way to kill crabgrass seeds and roots. This method involves covering the infested area with a clear plastic sheet during the hottest part of the summer. The heat trapped under the plastic will effectively sterilize the top layer of your soil, killing the crabgrass.

Use Boiling Water

Pouring boiling water on crabgrass is another effective method for small infestations. The hot water will kill the plant and its seeds. Be careful not to pour the boiling water on desirable plants or grasses, as it can kill them too.

Maintain Proper Mowing Height

Mowing your lawn at the right height can help control crabgrass. Keeping your grass slightly taller (around 3 inches) can shade the soil and prevent crabgrass seeds from germinating.

Apply Mulch

Applying a thick layer of organic mulch can also help suppress crabgrass. Mulch blocks light from reaching the seeds, preventing them from germinating. Plus, it adds nutrients to your soil, promoting the growth of healthy grass.

Preventing Future Crabgrass Infestations for the Next Season

To prevent crabgrass from growing in the next season, it’s important to take proactive steps that not only eliminate the existing crabgrass but also discourage its regrowth. Here’s how you can do it:

Apply Pre-emergent Herbicides Early

These herbicides work by preventing crabgrass seeds from sprouting. They should be applied in early spring, before the soil temperature reaches 55–60 degrees Fahrenheit, the optimum temperature for crabgrass germination.

Maintain Healthy Lawn Practices

A healthy lawn is your best defense against crabgrass. Regularly watering, mowing at the right height (around 3 inches), and fertilizing your lawn encourages the growth of healthy grass, which can outcompete crabgrass.

Aerate Your Lawn Annually

This practice reduces soil compaction by allowing water, oxygen, and nutrients to reach the grass roots more effectively, promoting the growth of healthy grass and discouraging crabgrass.

Use Post-emergent Herbicides If Needed

If crabgrass appears during the growing season, apply a post-emergent herbicide to kill it before it can set seed and spread further.

Regular Lawn Inspection

Regularly inspect your lawn for signs of crabgrass, especially during the peak growing season. The earlier you spot and remove crabgrass, the less chance it has to set seed and spread.

The Importance of a Crabgrass-Free Lawn

Maintaining a lawn free from crabgrass infestations is essential for several reasons. Firstly, crabgrass is an aggressive weed that competes with desirable grass species for sunlight, nutrients, and space, often outcompeting them and leading to a less healthy and aesthetically pleasing lawn.

Furthermore, crabgrass has a rapid lifecycle, producing thousands of seeds per plant in a single season. If left unchecked, these seeds can germinate the following year, leading to a recurring problem and making your lawn maintenance efforts more challenging.

Lastly, crabgrass is not just unsightly; it can also decrease your property’s curb appeal and potentially its value. A well-maintained, crabgrass-free lawn, on the other hand, adds beauty to your home and contributes to a healthier environment.

In conclusion, preventing and controlling crabgrass is an investment in the beauty, health, and value of your lawn. With the right strategies and consistent effort, you can keep your lawn lush, green, and free from crabgrass infestation. Remember, a little prevention goes a long way toward maintaining a vibrant and healthy lawn for years to come.
