Intensive Gardening Introduction
Bruce of Red Gardens has a good video on his experiences with both double-dug and no-dig intensive gardening:
Though I love what he’s doing here and enjoy double-digging, if you have more land go with wide spacing. Intensive beds are very resource intensive compared to spacing widely. If you don’t water a tightly planted bed you lose your plants quickly, whereas widely spaced crops can often subsist on rainfall alone.
