As with all true innovations, this gardening method is so simple, practical, and obvious that one just wonders, "Why haven't I thought of it before?" It works, and it's fun. Instead of doing a chore after a while, you are eager to work in the garden as you know each single plant, and watch their growth closely; almost like a pet. As an amateur, I have already begun to develop sub-systems and procedures for myself. Thank you Mel, and please include a wider range of tips concerning different climate conditions, natural fertilizers, etc. for us sq-foot gardeners on the other side of the world!
