Mowing
Piedmont Gold tall fescue should be 2 1/2 to 3 1/2 inches tall after mowing. As a general guideline, try to mow often enough that no more than one-third of the grass height is cut. Then practice grasscycling. Grasscycling is simply leaving grass clippings on your lawn. Grass clippings decompose quickly and can provide up to 25 percent of the lawn's fertilizer needs. If prolonged rain or other factors prevent mowing and clippings are too plentiful to leave on the lawn, they can be collected and used as mulch. Whatever you do, don't bag them! Grass clippings do not belong in landfills.
Fertilization
The best way to determine your lawn's nutrient needs is by a soil test. In the absence of a soil test, use a complete nitrogen-phosphorus-potassium (N-P-K) turf-grade fertilizer with a 3-1-2 or 4-1-2 ratio (that is, 12-4-8 or 16-4-8). Fertilize with 1 pound of actual nitrogen (N) per thousand square feet in mid-September and again in November (about the time the grass is green but not actively growing).*
Irrigation
Water to a soil depth of 4 to 6 inches. Probe with a screwdriver to determine moisture depth. Piedmont Gold tall fescue needs a weekly application of about 1 to 1 1/4 inches of water. On sandy soils it often requires more frequent watering—for example, 1/2 inch of water every third day. It is often necessary to irrigate an area for 3 to 5 hours to apply 1 inch of water. (It requires 640 gallons of water to deliver 1 inch of water per thousand square feet.) Because clay soils accept water slowly, irrigate just until runoff occurs, wait 1/2 hour until the water has been absorbed, and then continue irrigating until the desired depth or amount is obtained. A dark bluish gray color, footprinting, and wilted, folded, or curled leaves indicate that it is time to water. Proper irrigation may prevent or reduce pest problems and environmental stress later in the summer.
Weed Control
Apply broadleaf herbicides to control dandelions and other weeds if necessary. Caution: Some herbicides may affect newly seeded turf. Follow label directions
Insect Control
Check for white grubs in September and October and control them if necessary.
Aerification
Core lawns subject to heavy traffic or on clay soils to minimize compaction and improve rooting. Break up plugs.
Renovation
Piedmont and Coastal Plain Regions Only! Overseed thin, bare areas as grass begins to respond to cooler temperatures in September and early October. Use a blend of tall fescue cultivars at 6 pounds per thousand square feet. Apply a starter-type (high phosphorus) fertilizer at time of seeding. Keep the seedbed moist with light, frequent sprinklings several times a day to ensure good germination.
Thatch Removal
It is not necessary to remove thatch.
* To determine amount of product required to apply 1/2 pound of nitrogen per 1,000 sq. ft., divide 50 by the FIRST number on the fertilizer bag. Example: A 5-5-15 fertilizer. Dividing 50 by 5 = 10 pounds of product to be applied per 1,000 sq. ft. for 1/2 pound of nitrogen.
