Yeah, this is my back yard:
Terraced, and overgrown with trees and bushes. I think there are 10-12 trees of various sizes that the landscape architect said would need to come out to make grass viable. I'm choosing to disregard all their advice, spent $100 on various things at home depot, and am going to see what happens if I dump lime/fertilizer/grass seed back there this year. Worth a shot to possibly save a portion of $10k!
