Whether your lawn is a small patch of grass or several acres, it’s important to take care of it properly to keep it healthy all year long. The pros at Loyalty Lawn Care know the tips and tricks to keep your lawn green. But what about grassy weeds like crabgrass and foxtail? These pesky plant pests can overtake an otherwise healthy lawn and cause problems aside from the obvious visual concerns. The best way to ensure that these grassy weeds don’t ruin the look or health of your lawn is to use pre-emergent.

What is pre-emergent?

Often used alongside fertilizer, pre-emergent is not fertilizer itself. Instead, it is an herbicide that works to prevent grassy weed seeds from germinating. The reason that it is used in conjunction with fertilizer is because the latter is an effective carrier agent for the pre-emergent to bind to. This product is often referred to as weed and feed.

Should I add pre-emergent to my newly seeded lawn?

In a word, no. Because newly seeded lawns are still germinating, the pre-emergent can affect germination in the process. More mature lawns are sturdier against the herbicide, so it’s best to wait at least 4 months after planting the lawn to apply the pre-emergent. If you are unsure about the best timeline to follow for your lawn, don’t hesitate to reach out to Loyalty Lawn Care with your questions.

When should I apply pre-emergent?

Like many things when it comes to your yard, pre-emergent has seasonality to it. It’s most ideal to apply a pre-emergent herbicide before the temperature of the top 4 inches of soil reaches 55 degrees Fahrenheit for at least 5 days in a row. This translates to daytime highs of the upper 60’s to mid-70s for the same amount of time. We recommend considering a pre-emergent application in the late winter to early spring to maximize its effectiveness.

Every pre-emergent product is a bit different, but you can expect a single treatment to last approximately 3-5 months.

Can I overseed after applying pre-emergent?

While it is best to over seed in fall, after applying your preemergent, it’s important to give your lawn some time to for the product to lose its effectiveness before moving on to the next step. Therefore you shouldn’t be overseeding immediately after applying this herbicide – it’s best to wait at least 4 months between. If you must seed sooner some detailed prep work must be completed to assure you have a quality seed bed that won’t be harmed by the pre-emergent herbicide.
