Tall Fescue Care: Heat, Repair & State Plans

Protect existing turf before planning the next reseeding.

Turf-type tall fescue is a cool-season grass with a mainly bunch-forming growth habit. Its ability to tolerate a site is different from the ability of spreading grasses to replace large worn gaps.

Summer stress

Clemson’s South Carolina calendar holds back nitrogen during summer and avoids herbicides on heat- or drought-stressed fescue. A weak summer patch is not an automatic feeding instruction.

Mowing

Use the local home-lawn range and sharp blades. Frequency follows growth; avoid taking more than one-third of the leaf in a normal mowing.

Repair

Thin areas often need reseeding in a favorable establishment window. Check the cause, seed identity and capacity to care for new seedlings before preparing the whole lawn.
