Tall Fescue is a cool season grass. Unlike the warm season grasses such as bermuda, zoysia and centipede, fescue remains green during the winter. Although growing best in environments that receive regular rainfall, tall fescue has fairly good drought tolerance if not mowed too low during the warm season (no less than 4 inches in height).

In the South, tall fescue is best adapted to those states in the transition zone - Oklahoma, Arkansas, Missouri, Tennessee, Kentucky, Virginia and northern parts of North Carolina, Georgia and Texas.

Tall fescue performs best in the South with some afternoon shade, however will remain healthy in appearance in full sun under irrigated conditions and if the turf is managed properly. Although its wear tolerance is considered good for cool season grasses, it is not nearly as wear tolerant as bermudagrass.

Fescue Maintenance

The following suggested management practices are designed as a guidline to assist lawn care professionals and homeowners in the maintenance of a Fescue grass lawn. Location, terrain, soil type and condition, age of the lawn, previous lawn care, and other factors affect turf performance. For these reasons, the following management practices can be adjusted to suit your particular home lawn conditions.

Mowing

In the south, mow Fescue on an as-needed basis throught the year. A rotary-type mower set to cut at approximately 3 to 4 inches in height is recommended: three inches during the cool season and a minimum of 4 inches during the warm season. Never remove more than 1/3 of the leaf at any one cutting. Always use a sharp blade. Mow before grass gets taller than 5 inches. Catch and remove clippings unless using a mulching mower.

Fertilization

Spring - In February, apply a high-nitrogen fertilizer such as 20-4-10, preferrably containing a weed preventer such as Barricade to prevent the emergence of crabgrass and other weeds. NOTE: Do not use a weed preventer if you plan to overseed. Broadcast fertilizer using a rotary-type spreader following spreading rates recommended on bag.

Mid to Late Spring - Apply a high-nitrogen fertilizer such as 20-4-10, preferably containing a weed preventer such as Barricade. Broadcast fertilizer using a rotary-type spreader following spreading rates recommended on bag.

Fall - When temperatures begin to cool in early to mid fall, apply a high-nitrogen fertilizer such as 20-4-10, preferably containing a weed preventer such as Barricade. NOTE: Do not use a weed preventer if you plan to overseed. Broadcast fertilizer using a rotary-type spreader following spreading rates recommended on bag.

Irrigation

Though drought tolerant, Fescue requires infrequent deep watering during periods of drought. Do not over-water (avoid standing water for any period of time). A gray-green color, and wilted, folded, or curled leaves indicate that it is time to water. NOTE: Always water during the early to late morning hours and never at night. Watering at night will often lead to fungal development.

Weed Control

Preemergence herbicides may be applied any time of year so long as you are not planning to overseed.

To kill weeds that have emerged postemergence herbicides can be applied. Apply postemergence herbicides only when weeds are present. Spot treament is recommended during the warm season. Be sure the product is labeled for use on Fescue and always be careful to follow mixing and applications instructions on product label.

Thatch Removal

Thatching is generally not necessary.

Insect Control
