I can't really find what the problem with my lawn. Here in Houston, we had a drought since the start of April and lasted through the end of August of this year. Last year I fertilized it with Expert Gardener 15-5-10 slow release it ended up hurting my St Augustine. This year I fertilized it with Scotts 32-0-10 every 2 months and it killed my lawn. I watered it 2x a week because of the drought. I am beginning to think that my lawn does not need fertilizer as some my neighbors don't fertilized theirs. I know I am doing something wrong but just wanted to ask the experts.
