Lawn weeds are some of the toughest weeds to combat, and crabgrass is no exception. With the help of Blain’s Farm & Fleet, you can learn how and when to use crabgrass preventer.

When to Use Crabgrass Preventer

Crabgrass seed starts to germinate when the soil warms up. Initial emergence can happen when the soil gets to be about 54°F. The majority of seeds start to germinate when the soil reaches between 60 and 70°F. Depending on what type of climate you live in, this could be in early spring through mid-summer. Soil temp can also be affected by wind, moisture and the level of shade your lawn gets.

You’ll want to use the preventer before the seeds germinate. It should be applied when the soil reaches between 50 and 55°F. If it’s used too early, it can break down before the seeds start to germinate.

The best time to apply crabgrass preventer is before it rains. The rain will wash the preventer off the grass blades into the soil and the crabgrass seed.

How to Apply Crabgrass Preventer

Crabgrass preventer is a pre-emergent herbicide. It’s to be used before the crabgrass seeds have sprouted. To apply the preventer, use a lawn spreader or garden seeder. Apply it uniformly across your lawn, making sure to not miss any spots. After you’ve applied the herbicide, you’ll need to water it–unless it rains. If you have a newly-seeded lawn, wait until you’ve mowed your lawn a few times before applying an herbicide. Otherwise it can kill the grass seedlings.  Always follow the manufacturer’s instructions when applying a herbicide to your lawn.

Maintaining a healthy lawn and using mulch can also combat lawn weeds. Read through our article for more tips on fighting off lawn weeds.
