One of the most prolific and invasive turfgrass weeds found in East Texas is Virginia Buttonweed. It is a vining, low growing plant that can survive mowing at even the lowest blade settings. This broadleaf weed found most frequently in moist to wet areas produces a white, four star-shaped petal.
Overwatering or excessive rainfall during the growing period can lead to an onslaught of the weed in turfgrass. Therefore, withholding water until grasses exhibit drought stress symptoms can reduce potential weed growth. Post emergent broadleaf herbicides specifically targeting the Buttonweed and applied in early spring as perennial plants start emerging from dormancy, are helpful in managing the weed. Several applications are generally needed to keep it under control.
