It may seem like Jack Frost is trying to hang on to your landscape with his long, icy tentacles but don’t let the chill fool you. Spring is right around the corner and with it, a menace that homeowners fight every year, crabgrass.
Crabgrass is one of the most invasive weeds that we encounter in Kansas. It makes sense when you realize that a single plant can produce between 100,000 and 200,000 seeds. With this proliferation, it is virtually impossible to completely prevent crabgrass throughout the growing season. That being said, there are several things you can do to limit the amount of crabgrass in your lawn come July and August.
Maintaining a healthy stand of grass is critical in limiting crabgrass. Crabgrass finds its way into a lawn many times because the grass is thin or patchy. Regular watering and a fertilization program are important in keeping weeds to a minimum. Grass that is thick and lush acts much like a car cover on that classic Mustang in your garage, keeping your lawn running like a clean, green machine.
A crabgrass preventer is a great way to keep grassy weeds at bay. Getting that first application on before April 15 (or before the Redbuds bloom), is necessary as crabgrass begins to emerge at that time.
We typically apply a split rate application in March/April and then again in May. The reason for this is to get the benefit of extended control throughout what is usually a hot, stressful summer on many lawns in Kansas.
Most preventers on the market are designed to last for two to four months, and for good reason. Crabgrass preventers usually keep all grass varieties from germinating, because they can’t distinguish between the good fescue or bluegrass and the weedy grasses. They typically break down as we get to the latter part of the summer. This allows us to come in and overseed lawns that have taken a beating in the fall.
