Watering, lawn mowers, people and pets can readily spread North Texas Dallisgrass seed from one spot to another, so it’s important to immediately contact your Weed Man North DFW 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.

Dallisgrass can take a few years to appear after a home is built in North Texas.  These grasses are typically buried by the developer when they plotted the lot for your home with added dirt.  It is not uncommon to find these grasses several inches to several feet below the top soil when you dig a hole on the property. Over time, these grasses will make their way up and eventually appear in your lawn.  When this occurs will depend upon many variables, but if there is Dallisgrass buried under the soil, it is only a matter of time before it appears in your lawn.  No pre-emergent application can stop this from occurring because the grass has already germinated; pre-emergent products stop weeds and grasses at their initial germination stage.

A primary management key is to prevent the establishment of new Dallisgrass seeds through eradication and possibly lawn renovation under dramatic situations. North Texas Dallisgrass in St Augustine grass may need to be controlled through manual or mechanical methods as the best products that treat germinated Dallisgrass cannot be applied to a St Augustine lawn.
