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.
No Fescue Germination after 10 days. Last Saturday on March 8, I used a seeder to seed my front lawn with Vigoro RTF tall Fescue. 5400 sqft. I covered any bare areas with peat moss and began watering 3 times a day for 15-20 minutes at a time. I have not seen any germination now going on 10 days.
