Dallisgrass: The Clumpy Grass Taking Over Your Bermuda

Coarse Clumps That Survive Everything You Put on Them

Dallisgrass forms coarse, flat-growing clumps that spread outward in a ring, and it is one of the hardest weeds to get out of bermuda in north Mississippi. It is a perennial, it grows from underground rhizomes, and it shrugs off the products that handle crabgrass.

The clumps grow faster than the lawn around them, so they look untidy within a day or two of mowing, and the seed heads carry dark specks that look as though the plant has been dusted with pepper.

Because it is a perennial with rhizomes, digging it out rarely works. Any piece of rhizome left behind starts a new clump. It generally takes repeat treatment across a season, timed to the plant rather than the calendar.

We Treat Dallisgrass. Repeat post-emergent treatment across the season, timed to the plant. It is not a one-application weed.

How to Tell It From Crabgrass

People treat dallisgrass with crabgrass products all summer and wonder why nothing happens. They are different plants with different answers.

It Comes Back Every Year

Crabgrass is an annual and dies at the first frost. Dallisgrass is a perennial. If the same clump is in the same spot next season, it is dallisgrass.

Growth in a Ring

Clumps expand outward from the center, often leaving a thinner middle. Crabgrass sprawls flat from a single crown.

Peppered Seed Heads

Seed stalks carry dark specks that look like ground pepper scattered along them. That is the giveaway once it heads out.

Coarse, Wide Blades

Noticeably thicker and coarser than bermuda, with a pale vein running down the center of the blade.

Pre-Emergent Will Not Touch It

Pre-emergent stops crabgrass seed from germinating. Dallisgrass returns from rhizomes already in the ground, so it comes up regardless.

Wet, Compacted Ground

It favors low areas and packed soil, so heavy infestations often follow a drainage problem.
