If you have mowed and a day or two later you see yellow grass growing higher than your lawn, Yellow Nutsedge is the culprit. They are grass like, green with yellow spiky flower which is the seeds, and a V shaped stem. It is very tough to control because the roots which are also known as taproot or tubers that grow 8 to 14 inches deep in the soil. Regular weed killer will not get rid of these pesky weeds. Just like dandelions, do not pull them. Nutsedge have a very delicate root structure that can break at the slightest pull that the root will regenerate a new plant very quickly. Leave the plant alone to grow tall enough to be sprayed with herbicide. To inquire further about how All American can help you control Yellow Nutsedge, call the office at 402-408-0000.
