I'm intrigued by the idea of Square Foot Gardening, since I have so little space. But most of the "All New Square Foot Gardening" by Mel Bartholomew isn't applicable to Florida, for example the seasons and watering with sun-warmed (aka extremely hot) water. I'm wondering whether his suggestions for above ground boxes, soil mix, and plant spacing work here? The plant spacings seem too close to me. I think that when the rains and humidity come, such close spacings would encourage disease.

Has anyone tried SFG in Florida? How did it work out?
