The Q&A Archives: crabgrass and weeds

Question: can you prevent weeds from growing in your grass and what are the steps for treating your lawn all year around?

Answer: Maintaining a dense, healthy lawn through proper turf selection, establishment, and maintenance is the recommended non-chemical control for the crabgrasses. Avoid light, frequent irrigation, spring cultivation, short mowing, and summer fertilization. They can also be hand-pulled or mechanically removed.

Chemical Control - Apply preemergence herbicides before germination when soil temperatures stabilize at 50 - 55?F for several consecutive days; postemergence herbicides should be applied when plants are small.

Dandilions and other broadleaf weeds can be controlled with a chemical such as 2,4-D or by hand digging.

Feed your lawn 3 times a year, mow and water regularly and you should have a thick enough lawn to crowd out weeds.

Best wishes with your lawn!
