Crabgrass is one of the most prevalent and invasive weed species in turf in the Midwest. Once crabgrass gets a hold in a lawn or landscape, it can be difficult (but not impossible) to eliminate entirely.
Crabgrass is an ‘indicator weed’, in that its presence is an indication of other turf problems. For example, crabgrass plants tend to fill in bare or sparse areas in lawns where the native grass plants have been reduced due to disease, pests, or drought pressure. Once they fill in spots, they tend to spread through a variety of propagation means. A once-healthy lawn can soon become filled with crabgrass (and other weeds).
One of the best ways to defend against crabgrass invasion is to keep your turf healthy and full. ExperiGreen Lawn Care’s lawn specialists can help your lawn regain or maintain its health through a variety of programs. Ask ExperiGreen Lawn Care about some of our effective programs.
If your lawn has been prone to crabgrass in the past, or if it currently has the presence of crabgrass in it, there are some things you can do.
Pre-emergent treatment for crabgrass involves some planning and timing. In the Detroit area, crabgrass germination usually begins in early May, when the soil temperature reaches 62°F at a depth of 1 to 2 inches. To be effective, pre-emergent crabgrass herbicides have to be down before germination begins. It is safe to apply these if the average soil temperature is between 50°F and 55°F. The herbicide creates a barrier that stops or hinders crabgrass germination.
Post-emergent treatments are generally less effective and more damaging than pre-emergent treatments. Additionally, post-emergent treatments are most effective on young plants, but can also have an effect on more mature plants. The recommended treatment plan is 2 to 3 applications of herbicide, spaced 7 to 10 days apart to achieve a reasonable amount of control.
