Type of Weed: Sedge, Grassy Weed
Nutsedge (or nut grass) is a perennial grass-like weed with two main varieties known as purple nutsedge and yellow nutsedge. This hardy, fast spreading plant is known to grow across most of the United States and thrives in wet conditions.
These weeds arise from underground tubers each of which is capable of producing hundreds of new plants and tubers making it very difficult to control.
How to Identify
For control efforts to be effective, the underground tuber must be destroyed. Therefore, mechanical efforts and herbicides need to be targeted at killing all active and dormant tubers. It can be difficult for an amateur to properly time treatments and destroy all tubers. Utilizing the expertise of a professional lawn care company is the best chance of stopping nutsedge. This weed thrives in moist conditions, so eliminating excess moisture and improving soil drainage should also be part of your control plan.
