- 1). Mow your Poa-infected lawn weekly during the late spring and early summer when the seed heads are developing in profusion. Always use a catcher on your lawn mower to prevent the redistribution of seeds onto the thatch where they will germinate and start the plant process anew.
- 2). Spray a pre-emergent herbicide product on your Poa in early September before the seeds have a chance to germinate. Make a second application in the spring to catch the seeds as they are germinating. Repeat this treatment process every year until the problem is under control or eliminated. Apply the spray product according to the label directions being sure to wear a face mask to prevent accidental inhalation of the mist or vapors.
- 3). Apply a post-emergent herbicide product containing the active ingredient ethofumesate two to three times from September to December each year at four-week intervals. This product must be administered by a lawn care professional and is not sold retail. The limiting effect on the Poa can be seen in the fall after a treatment cycle but will improve even more the spring after treatment begins.
