Weed-opedia: Yellow Nutsedge
Yellow Nutsedge (Cyperus Esculentus)
What does it look like?: Tall patches (can get to 9-12 in. tall) of green leaves that produce clusters of spike-like yellow flowers. Each spike has dozens if not hundreds of seeds that can be transported to the rest of your yard by wind, animal, and/or mower.
What causes it?: Areas with loosely compacted soil that are consistently moist. May only last as long a stretch of wet weather or take root in an area with poor drainage.
When does it show up?: Spring – Fall
Best treatment plan: Post-emergent herbicide treatments work best for this pest because of how easily its seeds can be dispersed. Call a professional for a free quote.
How long will it take to get rid of it?: May take up to 3 weeks of diligent herbicide applications before it is fully taken care of. Watch any problem areas to see if it resurfaces.
