Been working on this for several weeks now. That is where i have been. We also hit Starbucks, where you can pick up their used organic coffee to enrich your soil with. You go in and ask for their grounds for grounds and they will hand it over. It is an excellent almost neutral (ph 6.9) additive. My favorite it is free. We also put manure and compost in this. it is about 12 feet by 15 feet. It is almost ready for plant life.
