| what is the best way to get rid of crabgrass other than hand weeding? when is the best time of year to do this? |
| Crabgrass starts germinating when soil temperatures are 50 to 55 degrees F for ten or more days and germination can take place over a 6 week period. Pre-emergence herbicides provide excellent weed control for crabgrass but they last only about 30 days. The compound prevents the weed seed from germinating, but it won't kill the newly sprouted seedlings. Late April to early May is an ideal time to apply pre-emergence control. A second application might have keep your lawn a little more crabgrass free. At this point, you might want to try raking it out or hand pulling. Next spring use the pre-emergent again, reapplying in 30 days. That should keep the crabgrass under control. Proper lawn maintenance practices can limit crabgrass invasions. A dense stand of turfgrass prevents the weed from germinating and establishing. Best wishes with your lawn. |
