Tall Fescue Grass Fundamentals
Fescue grows in clumps via tillers — NO rhizomes, NO stolons. It does NOT spread laterally to fill gaps. Damaged areas stay bare until you seed them. Always use Turf Type Tall Fescue (TTTF) varieties — NEVER K-31 pasture fescue, which is coarse, clumpy, and ugly in a lawn setting. Modern TTTF cultivars (Rebel IV, 4th Millennium, Titanium 2LS) offer finer blades, better density, improved shade tolerance, and enhanced disease resistance. Fescue produces very little thatch — a significant advantage over Kentucky Bluegrass.
Frequently Asked Questions
What is a tiller?
A tiller is a new shoot that grows from the base of an existing plant. Fescue produces new tillers to thicken, but they stay in the same clump. Tillers cannot spread to fill bare spots.
Why can't fescue repair bare spots?
Unlike Kentucky bluegrass (rhizomes) or bermuda (stolons + rhizomes), fescue has no lateral spreading mechanism. A bare spot stays bare until you add seed. This is why annual overseeding matters.
How deep do fescue roots grow?
Tall fescue roots reach up to 24 inches — the deepest of any cool-season grass. This deep root system gives fescue excellent drought tolerance and heat survival compared to KBG.
