If Your Lawn Does This – You’ve Got a Problem on Your Hands

If you’ve been sitting back and admiring your lawn this year, that’s great! But I want to share something crucial with you—something that can sneak up on you if you’re not careful. If you start seeing certain signs in your lawn, it could mean you’ve got a serious grub problem on your hands. So if your lawn starts showing these signs, act quick or you could be set back a few seconds on all the progress you’ve made.

What Grub Damage Looks Like

First things first—let’s talk about what to look for. Grubs are sneaky little pests that can do a lot of damage without you even realizing it until it’s almost too late. Here’s what you should keep an eye out for:

• Dead or Brown Patches: Have you noticed large sections of your lawn turning brown or just dying off, especially toward the end of summer? That’s a big red flag. Grubs feed on the roots of your grass, and when they’ve had their fill, your lawn can’t stay green and healthy.
• Loose Grass: Give your lawn a gentle tug. If it lifts easily, almost like a loose carpet, that’s another clear sign of grub activity. Those little pests have been chomping away at the roots, and without them, the grass just can’t stay anchored in the soil.
• Animal Activity: If you start seeing birds, raccoons, or skunks digging up your lawn, they’re not just out for a snack—they’re hunting grubs. While they might help reduce the grub population, they’ll also tear up your lawn in the process.
• Thin or Wilting Grass: Even if you’re watering your lawn, some areas might still look thin or wilted. This happens because grubs have weakened the roots so much that the grass can’t get enough water or nutrients.

Why Nematodes Are Your Best Friend

So, what do you do if you suspect grubs are taking over? One of the best, most eco-friendly solutions is to use beneficial nematodes. These microscopic organisms are like nature’s pest control. They seek out grubs and other soil pests, infect them, and then move on to the next victim. The best part? Nematodes won’t harm your pets, kids, or the beneficial insects in your garden.

When and How to Use Nematodes

Timing is everything. The best time to apply nematodes is late August to early September. This is when grubs are young and close to the soil surface, making them easy targets. Here’s how to do it:

1. Prep Your Lawn: Water your lawn thoroughly the day before applying nematodes. They need moist soil to move around and find the grubs.
2. Apply in the Evening: UV light can kill nematodes, so apply them in the evening or on a cloudy day. Use a hose-end sprayer or watering can to spread them evenly across the lawn.
3. Keep the Soil Moist: After applying, keep the soil moist for at least two weeks. This helps the nematodes stay active and effective.

Watching for Results

After you’ve treated your lawn, you should start seeing some positive changes. Animals will stop digging up your lawn, and those dead patches should gradually fill in with healthier grass. But remember, nematodes aren’t a one-and-done solution. You might need to reapply them annually or as needed to keep grubs in check.

Preventing Future Grub Problems

The best way to deal with grubs is to stop them before they become a problem. Regularly inspect your lawn, especially during the mid to late summer. If you see any suspicious patches, do a quick tug test to check for grubs. And remember, a healthy lawn is your best defense. Keep up with proper mowing, watering, and fertilization to make your lawn less inviting to grub-producing beetles.

So, if you notice your lawn doing any of the things I mentioned, don’t ignore it. Grubs can do some serious damage, but with a little effort and the right approach, you can keep your lawn looking lush and green. Let’s nip this problem in the bud, and your lawn will thank you for it!
