This question is aimed at SWD because he lives in my area and has excellent knowledge of Bermuda. But anyone that feels so inclined, please respond. Scenerio: Bermuda lawn is residential and the lot is on the side of a hill that runs downhill west to east. Front of house faces south so lawn is sloped to run south east away from the house. Lawn is approximately 8000 sq feet. In the middle of the lawn on either side (West, East) is an arizona ash and a Silver leaf maple. Both are muture 15 years old. Problem: Bermuda grass ( standard bermuda) at the top of the hill is thin, and full of bare spots. It is full of crabgrass, clover, and dandelions. Went over it with MSMA and cleared out most of the clover and the dandelions. Still have a problem with crabgrass. The bottom of the hill is thick and lush. This leads me to 2 issues. Too much shade from the tree canapy, and top soild washing down to the bottom of the lawn. Here is my question. If I thin the canapy and topdress the top area, will that help restore the lawn. Also, the soil is mainly clay as a result of them cutting the lot out of a side of a hill. If you were to start now restroring the lawn, what would your steps be? No I haven't done a soil test. Need to. What fertilizer if any would you use, topsoil mix, etc. I have even thought of ripping it out and replacing it with St. augustine, but that is really a last resort. Words of advice?
