How to treat Dallisgrass

Make sure that when handling a herbicide, you are wearing protective gears to protect your skin and eyes(Goggles, gloves, and long-sleeved clothing)

To get rid of Dallisgrass, chemical options are the best way, especially if you have an outbreak that will be time-consuming. We recommend using a pre-emergent herbicide to prevent Dallisgrass.

If your lawn suffering from heavy Dallisgrass, we suggest you use both pre-emergence and post-emergent herbicides. We recommend using a pre-emergent herbicide in early spring to kill seedling weeds and post-emergence herbicide treatment.


How to prevent Dallisgrass

Dallisgrass is a perennial plant. You have no chance to prevent the grass from coming back. You need to make sure your yard is healthy and densely planted with turf. Routinely mow your lawn at 3 to 4 inches to help the turf better resist a reinvasion of Dallisgrass. For problems in ornamental beds, you may need to add mulch.

A late winter to early spring pre-emergent is a great way to stop the invasive grassy weed from returning and spreading. Use an appropriately calibrated sprayer and then apply the herbicide until your lawn is covered evenly.
