Knowing what weedy grass you have in your lawn or landscape is very important in being able to properly control it. Dallisgrass is a common perennial weed that is easily identified and grows in uneven clumps in lawns and turf. This growth pattern creates a tripping hazard as well as a poor playing surface for parks, front lawns, and athletic fields. Clumps must be dug out to prevent its growth. Solarization with clear plastic can help control dallisgrass.
For more details about the biology of dallisgrass, management methods, and extensive information about herbicides, see the newly updated Pest Notes: Dallisgrass, authored by UC Cooperative Extension...

In order to know how to manage weeds correctly, you'll need to identify the weeds and understand their life cycle. Certain weeds are associated with conditions such as compacted soil, overwatering, and poor drainage.
