Okay so here's my situation. My house is about 15 years organic/pesticide free with natural, local plants. It's pretty hippy dippy. In keeping of the spirit of the previous homeowners decision to go this route, what would you suggest to do with my backyard lawn. The lawn is basically a weed/grass that comes and goes with the seasons which can be unappealing. It takes a ton of water in the summer months to keep the dream alive, if you know what i mean. One thing that I absolutely need to do is Aerate the soil. Can I run a big aerator over my existing grass with out completely annihilating it?
