Two specially timed service visits, spaced approximately 7-14 days apart, are scheduled in the early summer. This application cannot be performed in a St. Augustine lawn and is for Bermuda lawns only. Dallisgrass is the most difficult to control of all weeds.
Dallisgrass is a perennial grass with light-green color. Dallisgrass is easily identified by its long seed-heads that protrude from the top. Dallisgrass tends to thrive in wet areas with lots of heat, and grows in circles out from the center of the weed.
