How to Get Rid of Weeds in Your Lawn in Connecticut
You step outside, take a look at your lawn, and there they are—weeds. Sprouting between the grass blades, crowding out the good stuff, and messing up that clean, green look you’ve been going for. It’s frustrating, and if you’re in Connecticut, it’s something most homeowners face every year.
The good news? Weed control doesn’t have to be complicated, and with a few smart steps, you can take your yard back.
Why Weeds Show Up
Weeds thrive where grass struggles. Thin spots, compacted soil, and poor drainage give them a chance to move in. In Connecticut, the most common lawn invaders include crabgrass, dandelions, clover, and plantain.
Once they get a foothold, they can spread fast—especially if your lawn isn’t strong enough to fight back.
Start with Prevention
The best way to control weeds is to stop them before they start. A thick, healthy lawn will naturally crowd out weed growth. Here’s how to give your grass the upper hand:
Mow at a higher setting (around 3 to 4 inches)
Water deeply once or twice a week, rather than shallow daily watering
Fertilize your lawn at the right times (check out our fertilization guide)
A healthy lawn is your first and best line of defense.
Use Pre-Emergent in Spring
If you’ve dealt with crabgrass or other annual weeds, pre-emergent treatment in early spring is key. It works by stopping weed seeds from sprouting—before they become a problem.
In Connecticut, this is usually done in April, when soil temps hit around 55°F. If you wait too long, the window closes.
Spot-Treat With Post-Emergent
For weeds that are already up and growing, use a selective post-emergent herbicide that targets broadleaf weeds while leaving your grass alone. Spray on dry, warm days (ideally between 60–85°F), and don’t mow right before or after—give the treatment time to do its thing.
Don’t Forget Manual Removal
If the weed situation isn’t out of control, pulling them by hand can still be a solid move. It works best after a rainfall, when the soil is soft, and always aim to pull the entire root. Otherwise, they’ll just bounce back.
Fill the Gaps
Weeds love bare patches, so don’t give them any. Aeration and overseeding in the fall can help thicken your lawn and prevent weeds from taking over next season. You can learn more about that on our lawn care service page.

Weeds are annoying, but they’re not unbeatable. With the right strategy and a little consistency, you can take control of your lawn and keep it looking clean, thick, and healthy through the season.
