Plant fescues when fall temperature reach about 75 F. The next best time to plant fescue seeds is when rising temperatures in spring reach 60 F. Summer isn't a good time to plant fescue lawns, because fescue grass tends to go dormant during periods of high temperature.
DO NOT fertilize tall fescue after March 15. Tall fescue needs 1 to 11â4 inches of water every week, ideally NOT all at once. A dark bluish-gray color and wilted, folded, or curled leaves indicate that it is time to water. Water until the soil is wet to a depth of 4 to 6 inches. Use a screwdriver or similar implement to check.
