So I have a few issues. I have thin grass, weeds and uneven spot everwhere. I just dont know where to start. Should I start with one before the other? I have read a lot about scalping and then leveling with sand, should I do that? I know people say bermuda is strong but I feel if I scalp my lawn I dont have enough for it to grow back. I did not apply any pre-m for weeds so I am behind already and I havent put down any fert. I do have irrigation in the front. Any advice will be great! Not to mention my neighbor is on top of things and uses a reel mower. I gotta step my game up!
