Yellow nutsedge is a persistent perennial weed of poorly drained soils. Yellow nutsedge is grass-like in its appearance with parallel leaf veination. The stem of nutsedge is triangular with leaves coming off each corner (three-ranked). Nutsedge is very difficult-to-control and can produced hundreds of thousands of seeds per plant per season.

Nutsedge is particularly a problem in years of above average rainfall and the following year. It will grow faster than the surrounding turf. Nutsedge is a common invader of landscape beds.
