Homeowners in Ortonville, Michigan, know that crabgrass can quickly take over a lawn if not controlled properly. To prevent crabgrass from invading your yard, the key is early prevention. In Ortonville, it’s best to apply a crabgrass pre-emergent herbicide in mid to late spring, before the soil temperature rises to 55°F at a one-inch depth. The crabgrass pre-emergent will kill crabgrass plants right after they germinate, preventing crabgrass plants from taking root in your lawn.

 

Maintaining a healthy, dense lawn is another key to crabgrass prevention. Proper lawn fertilization, along with consistent mowing at the correct height, will keep your grass growing thick and strong. Taller grass naturally shades the soil, reducing the likelihood of crabgrass seed germination.

 

In addition to applying a crabgrass preventer, make sure your lawn receives adequate water. Deep, infrequent watering promotes strong root systems, making your grass less vulnerable to weeds like crabgrass. During typical weather conditions, you should apply 1” of water per week to keep your lawn properly hydrated.

 

Lawn aeration can also improve soil health, ensuring your grass has the best environment to grow. Aeration improves soil and lawn health by increasing the movement of air, water and nutrients to the root zone of your grass plants. Aerating also reduces soil compaction, allowing for improved root growth.

 

By staying proactive and following these steps, homeowners in Ortonville can prevent crabgrass from taking hold and will help you to maintain a lush, weed-free lawn throughout the growing season.
