Centipedegrass

Description

Centipedegrass is a slow-growing, coarse-textured, warm-season turf that is adapted for use in low maintenance situations. It is often referred to as "lazy man's grass" due to its infrequent mowing and fertilization requirements. It also has a light-green color and spreads by stolons. It does not tolerate traffic, compaction, high pH, excessive thatch, drought, or heavy shade. Centipedegrass can often be confused with St. Augustinegrass. However, centipedegrass has alternating leaves at the nodes whereas St. Augustinegrass has opposite leaves at the nodes. Centipedegrass also has a more pointed, slenderer leaf blade than St. Augustinegrass. Both leaf blades are V-shaped in cross section, but that of St. Augustinegrass has a more obviously boat-shaped tip.

lawn Maintenance for September - November

Fertilization

Fertilize with 1 pound of potash (K2O) per 1,000 sq. ft. 4 to 6 weeks before expected frost using 1.6 pounds of muriate of potash (0-0-60) or 2 pounds of potassium sulfate (0-0-50). DO NOT lime centipedegrass unless recommended by soil test. To determine amount of product required to apply 1 pound of potash per 1,000 sq. ft., divide 100 by the THIRD number on the fertilizer bag. Example: A 6-6-12 fertilizer. Dividing 100 by 12 = 8.3 pounds of product to be applied per 1,000 sq. ft. for 1 pound of potassium.

Insect Control

Check for white grubs and control if necessary.

Irrigation

Water to prevent drought stress. About 1 inch of water per application each week is sufficient for growing centipedegrass. Sandy soils often require more frequent watering; i.e., ½ inch of water every third day. Water following onset of dormancy (browning of foliage) if needed to prevent excessive dehydration.

Mowing

Mow lawn at 1 inch. Mow before grass gets above 1 ½ inches tall. Raise mowing height to 1 ½ inches several weeks before expected frost.
