Hi! We bought a new house 3 years ago and I want to improve the yard. It's very thin bermuda in sunny spots and very dark green, healthy fescue in shady spots. There are quite a few bare spots where the soil is mostly clay. Last fall, I added top soil and fertilizer to those spots and tilled and seeded with fescue, but apparently a different type than the fescue that was already there. It sprung up quickly and grew well all winter and spring, but as soon as the summer sun hit, it quickly dried up and died. It re-grows everytime I water it or it rains for an extended period of time, but after even a week or two of none or inconsistent watering, it's dead again. The seed I used is Pennington Seed Fescue Plus, which is 44% fawn tall fescue, 34% greystone tall fescue, and 19% signia tall fescue. What should I do? Should I reseed with a different type of seed? What would you guys recommend for a shady, zone 7 grass that will have to go through a dry and wet spell every year? Also, what can I do to thicken up my bermuda?
