How to Eradicate Cyperus Rotundus
Cyperus rotundus, or nutsedge, is found in California coastal valleys. Thriving in regions with soil, when the plant is established it may endure through even drought and regular watering. The crops are perennial, with the stalks and leaves when temperatures drop dying back, growing again in the spring from the rhizomes and tubers that live in the dirt. Controlling these tubers will be the key to controlling and removing Cyperus rotundus.
Eliminate when they are small, until 5 to 6 leaves appear — the time when tubers start to grow. Continue removing every 2 to 3 weeks throughout the summer, the crops, forcing the old tuber to use its resources that are stored up. Pull up by hand or dig with a hand hoe. When using a hand hoe, remove by digging to 14 inches .
Eliminate the conditions. Site drainage or work developments, such as peat moss, into the soil.
By using landscape fabric made from polypropylene 17, prevent the reappearance of nutsedge cleared. Spread the fabric in which you want to protect against the nutsedge and cover the fabric with several inches of mulch or gravel out.
Eliminate from patches of lawn the dirt by digging a minimum of 8 inches deep, refilling with clean soil, then sod or seed the region.
Assuming a heavily infested area throughout the summer, letting the tubers to dry in the sun. Withhold all water into the area. Continue to dry and till the tubers. If nutsedge still appears in isolated areas, pull the plant or hand hoe the tuber out.
Plant shade to control nutsedge. For instance, tall or replacing an infested bed of annuals with shrubs, dense soil cover can control nutsedge growth.
