Why Is Crabgrass Such A Problem?

This is an annual grass which dies off in the winters but not before leaving around 150000 seeds for each plant. The rate of their growth is highly uncontrolled and this results in their rapid spread in no time.

How to Keep It Away Once It’s Gone

One of the major challenges even after you have managed to kill and remove the crabgrass is the prevention of them being back again. For this you must always be vigilant as the crabgrass can make its way back in no time. Whenever you find one you must uproot it from the roots with immediate effect.

Afterwards mulch the soil surrounding it so that the seeds if any, do not get the chance to make a comeback. You have to be particularly aware during springtime with the temperatures crossing 55 degrees as this is the time the seeds usually germinate. You can use fertilizers and pre emergent herbicides at the places where they are more likely to occur. Lastly have a healthy lawn with lush green grass and maintain it well as then it becomes increasingly difficult for crabgrass to find its way in.
