Weeds in your Lawn

Some of the summer weeds we are seeing in Lancaster County lawns are nutsedge, dallisgrass, and crabgrass. These weeds incubate in moisture and humidity. Unfortunately, there is limited pre-emergent treatments for nutsedge and dallisgrass in particular. Here are a few characteristics of these weeds:

  • Nutsedge grows above the turf and has the triangular stem with yellow-green leaves arranged in threes. Nutsedge is very easy to pull out; however, it leaves a small tuber that sprouts a new plant.

  • Dallisgrass is a perennial grassy weed with 1/2 inch wide leaves that grow to 4 to 10 inches long. The leaf is a lighter green than the crabgrass blade.

  • Crabgrass is an annual grassy weed that forms into broad, flat clumps in the lawn. The blade is 2 to 5 inches and is 1/3 of an inch wide. The blade is a darker green when compared to dallisgrass.

We recommend treating crabgrass with our yearly pre-emergent application programs. For nutsedge and dallisgrass the pre-emergent treatments do not keep these weeds from growing. We treat nutsedge and dallisgrass with spot treatments of herbicides. Contact us for options for treating the weeds in your lawn.
