Watering, lawn mowers, people and pets can readily spread Dallisgrass seed from one spot to another so it’s important to immediately contact your local Weed Man professional to identify and control dallisgrass in your lawn.
Dallisgrass seeds generally germinate in the spring and summer when soil temperatures are in the 60- to 65-degree range resulting in clumpy patches of grass. The patches are coarser in texture and can present a tripping hazard where children regularly play.
A primary management key is to prevent the establishment of new Dallisgrass seeds through eradication and possibly lawn renovation. Dallisgrass in tall fescues may need to be controlled through manual or mechanical methods.
