If a weed is just a ‘plant out of place’,  then nutsedge takes its job seriously. Yellow nutsedge is native to North America, but can be found worldwide anywhere it’s warm. Purple nutsedge is not as well traveled, and prefers slightly warmer weather. Both species are perennial and dig the summer when the living is easy – but can tolerate and grow year round in Florida. Nutsedge is not too particular about where it grows – it’s just as at home in your lawn as it is in a pasture. As with most weeds, keeping your lawn healthy can help keep nutsedge at bay. Unlike many weeds, nutsedge is not deterred by landscape fabrics, plastic mulch, or other types of mulch. Once it has a foothold in your turf, it can be hard to get rid of. Nutsedge spreads via rhizomes and tubers. For small outbreaks, hand pulling can be effective. You will need to remove all rhizomes and tubers, and will need to check the area repeatedly. This will take time, but is effective and environmentally friendly. If your turf is overrun with nutsedge, an herbicide might be the only option. Consider calling a professional  for a safe and effective application. Check out the link and video below for more information.
