Crabgrass is a common lawn weed, but it can cause significant damage if not addressed, particularly during springtime in Indiana. At SunBlest Lawn Care, we understand that taking early action is crucial. If you’re a homeowner in the Indianapolis area, now is the time to take control. With the right strategy and timely crabgrass control treatments, you can prevent this aggressive invader from turning your yard into a patchy mess.

When Crabgrass Starts to Grow in Central Indiana

As the soil warms up, crabgrass begins its seasonal comeback each year. In Indiana, this usually happens between late March and May, when soil temperatures stay above 55°F for several days. Once seeds start to sprout, crabgrass spreads fast; once it’s visible, it’s already difficult to manage.

Why Pre-Emergent Treatments Work Best

The most effective way to prevent crabgrass from taking hold is to apply a pre-emergent weed control treatment. These treatments form a protective barrier that stops the weed seeds from germinating. However, timing is crucial—apply it too early, and the protection fades before it’s needed; apply it too late, and the weeds are already growing.

At SunBlest Lawn Care, we monitor local soil and weather conditions to apply crabgrass control at just the right time, so your lawn gets protection when it matters most.

Missed the Window? There’s Still Hope

Not all is lost if crabgrass has already started appearing in your yard. Early post-emergent applications can help prevent young weeds from spreading. Acting quickly is key here—mature crabgrass is much harder to control and can stick around until fall if ignored.
