I have a customer that I've had for several years. They're backyard (1500sq') they want very nice. I've tested the soil and followed the recommendations, sprayed tea, aerate and over seed every fall. They have a lot of trees but cut several down to allow more light in. I've put down just fescue, and a mix of rye, fescue, and kbg. It grows nicely and then dies. They have 2 dogs that they swear they keep off the seed. Before they hired me they've tried other companies and no one can get anything to grow. One of the women is obsessed with watering and I believe she over waters the seed. I got an e mail from them yesterday saying they want to dig up the lawn and start from scratch with either seed or sod. Any thoughts on this.
