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.
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.
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 the bag.
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.
Pre-emergent - Preemergence herbicides may be applied any time of year as long as you are not planning to overseed.
Post-emergent - 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.
