Best approach: Herbicide spray
Dallisgrass has extremely deep roots — digging rarely gets it all and it regrows. Spot-spray with glyphosate and reseed the area, or use a selective grassy weed herbicide.
When to treat Dallisgrass

Apply a grassy weed herbicide (fluazifop or sethoxydim) when actively growing in spring or early summer, or use glyphosate for spot treatment. Repeat applications often needed.
