Nutsedge

Nutsedge is a common, and often annoying, lawn weed. Two varieties problematic in Florida are purple and yellow nutsedge.
You can recognize these plants by their long green blades and spiky seedheads that resemble sandburs.

Nutsedges are perennial, and can survive and reproduce from underground nut-like tubers in almost any kind of condition except for shade.

Like any weed, nutsedge is best kept in check with an appropriate lawn maintenance program. Mowing, fertilizing, and watering the lawn properly all contribute to its health, and can go a long way to preventing weed infiltration.

If nutsedge is a problem in your lawn, you can hand-pull the plants or apply an herbicide labeled for use on this weed. Spot-treat only and always follow label instructions.
