As our mild Dallas winter quickly transitions to spring you may be seeing some patches of prolific green grass on your lawn. If so, it's likely Poa annua or simply Poa grass. This is not a grass at all, but rather a weed that can grown in any little crack or crevice and as Neil Sperry tells us "it thinks it’s gone to weed heaven when it gets free reign over a home lawn like the one in the photo."

Neil goes on to say that "This is a cool-season weed. That means that it germinates in the fall, grows a bit before winter, and then really takes off when the warm days of late February and March roll in. By April it’s in full bloom like a million little pampasgrass plants, and ripe seeds are only days behind.

The only means of addressing this weed is by preventing it. There is no control once it gets started. Since it germinates in early fall, you must apply a pre-emergent herbicide between August 25 and September 7. If you miss that timing, you’ve blown it for another entire year." Winter maintenance and regular mowing can also help keep the problem manageable.

At this point in the growing season, just keep it mowed as best you can. Your permanent lawngrass will soon be growing vigorously, and this annual bluegrass will quickly fade into history.
