Dallisgrass in Roanoke: The Complete Guide


Dallisgrass is a common weed that plagues lawns and pastures in Roanoke, Virginia. It's an aggressive plant that can quickly take over and ruin the appearance of your landscape. But with the right approach, keeping dallisgrass under control and maintaining a beautiful lawn is possible.

What is Dallisgrass?

Dallisgrass is a warm-season perennial grass commonly found in the southeastern United States, including Virginia. It is often considered a weed due to its ability to outcompete other grasses in pastures and lawns.

What Does Dallisgrass Look Like?

Dallisgrass has long, flat leaves with a distinctive V-shape and a shiny, waxy appearance. Its stems grow upright and can reach up to three feet in height, and it produces seed heads with small, spiked flowers that can be easily spotted in a lawn or garden.

Dallisgrass vs Crabgrass

Here in Roanoke, two of the most common types of weeds found in yards are dallisgrass and crabgrass. Here’s how you can tell what you have on your lawn:

  • Dallisgrass has wider blades than crabgrass.
  • Dallisgrass grows in clumps, while crabgrass spreads out more horizontally.
  • Dallisgrass is a perennial weed, while crabgrass is an annual weed.
