Identify Crabgrass in Your Lawn

Before taking any steps to get rid of crabgrass in your lawn, it’s essential to identify it.

Crabgrass is a weed that can easily be recognized by its wide leaves and stems that grow close to the ground. It’s also known for its shallow roots that form a bunch.

If left untreated, crabgrass can quickly take over your entire lawn, making it unsightly and difficult to manage.

By identifying crabgrass early on, you can take the necessary measures to prevent it from spreading and damaging your lawn’s health.

Remember that different types of grasses and weeds may look similar to crabgrass, so it’s best to consult with a lawn care professional if you’re unsure about what you’re dealing with.

1) Use Pre-Emergent Crabgrass Control

After identifying crabgrass in your lawn, the next step in controlling it is by using pre-emergent herbicides.

This technique works best before crabgrass seeds germinate and begin to grow, making it crucial to apply in the spring or fall.

Following the manufacturer’s instructions is essential to prevent harming your lawn. Once the crabgrass has emerged, it’s best to use a selective post-emergent crabgrass killer for effective control.

However, if you missed the pre-emergent application window, you can still inhibit the seedlings at the 2-leaf stage. Hand-weeding for small areas can also be an option.

Maintaining proper lawn care techniques and monitoring for future outbreaks can help prevent crabgrass from taking over your lawn again.

Remember to research and consider professional lawn care services for additional assistance.

2) Spot-Treat with Post-Emergent Herbicides

Once you have identified crabgrass in your lawn and used pre-emergent crabgrass control, it’s time to move on to spot-treating with post-emergent herbicides.

These herbicides are designed to target and kill existing crabgrass plants specifically.

However, applying them at the right time is important – typically when the crabgrass is actively growing and has not yet gone to seed.

If misused or at the wrong time, post-emergent herbicides can harm desirable plants in your lawn.

It’s also important to follow the instructions on the label carefully and to wear protective clothing, as these herbicides can be harmful if not handled properly.

While spot-treating with herbicides can be effective for small areas, it may not be the best solution for larger infestations.

In those cases, it may be necessary to consider professional lawn care services. Remember to monitor and repeat treatments as required and to practice proper lawn maintenance to prevent future crabgrass outbreaks.

Combining several strategies, you can successfully rid your lawn of crabgrass and enjoy a healthy, lush lawn.

3) Apply Herbicides at the Right Time

Once you have identified crabgrass in your lawn, the next step is to apply herbicides at the right time to eliminate it effectively.

This means using a pre-emergent herbicide like Barricade several weeks prior to expected crabgrass germination.

If crabgrass has already become established in your lawn , a post-emergent selective herbicide should remove the weed while leaving your lawn grass unharmed.

It’s crucial to apply herbicides at the right time for them to be most effective. Pre-emergent herbicides should be applied before Forsythia flowers drop, usually in most areas in late April or early May.

Meanwhile, post-emergent herbicides should be applied when the crabgrass is actively growing.

By following these timing guidelines and other crabgrass control techniques, you can successfully combat and prevent crabgrass outbreaks in your lawn.

4) Consider Professional Lawn Care Services

If crabgrass has taken over your lawn and you’re feeling overwhelmed, it may be time to consider hiring professional lawn care services.

A trained professional can evaluate the extent of the crabgrass infestation and provide an effective treatment plan.

They can also advise on the best long-term strategies to prevent future outbreaks.

While tackling a crabgrass problem alone can be time-consuming and stressful, working with a lawn care expert takes the pressure off and ensures a healthier, weed-free lawn. Don’t hesitate to contact a trusted professional to get your lawn back on track.

5) Hand Weeding for Small Areas

If you have a small area of crabgrass in your lawn, taking care of it by hand weeding is an option.

It may be time-consuming, but it is an effective way to remove the weed from your lawn without harsh chemicals.

Use gloves to protect your hands, get right down to the root of the crabgrass plant and pull it out. Ensure that you remove the entire weed, including the underground root system.

Discard the weed in a heavy-duty garbage bag so it won’t spread to other areas. Hand weeding works best for small infestations, but more significant outbreaks may require professional help or herbicides.

Remember to keep your lawn healthy by regularly watering and mowing it at the recommended height to help prevent future outbreaks.

6) Monitor and Repeat Treatments

Once you have applied the pre-emergent and post-emergent herbicides to your lawn to fight crabgrass, it is crucial to keep monitoring the area and repeating treatments as necessary.

Some crabgrass seeds may remain dormant in the soil and can sprout again after the initial treatments. Therefore, it is vital to remain vigilant and check your lawn regularly.

If you see any signs of crabgrass, spot-treat the area with post-emergent herbicides as soon as possible.

Moreover, keeping up with regular lawn maintenance tasks, such as mowing, watering, and fertilizing, will help prevent future crabgrass outbreaks.

If you follow these tips and techniques, you will enjoy a healthy, beautiful lawn free of pesky crabgrass.

7) Prevent Future Crabgrass Outbreaks

After removing existing crabgrass from your lawn, it’s important to implement preventative measures to ensure future outbreaks don’t occur.

This means practicing lawn maintenance, including mowing at the proper height and installing an irrigation system.

Applying pre-emergent weed killers in the spring, such as corn gluten meal, can also prevent crabgrass from sprouting.

It’s also essential to choose the right herbicides for spot-treating future outbreaks and apply them at the right time to ensure maximum effectiveness.

By monitoring your lawn regularly and repeating treatments as needed, you can ensure that your lawn remains healthy and free of crabgrass.

Following these preventative measures allows you to enjoy a lush, green lawn all season long.

Regular watering, about one inch per week, is also important for a healthy lawn.

Fertilizing with a high-nitrogen fertilizer in the fall will help thicken the grass and prevent another crabgrass outbreak the following year.
