I am experimenting with growing a garden in leaves! Nothing but leaves!
Let me tell you how much I am loving this... I built two fences about 2 to 3 feet apart and filled it with last years oak leaves about 2’ high (I had to do something with them anyway). I can leave the garden for more than a week and the plants don’t need watered, everything I have planted is doing great in spite of frosts, chipmunks, neglect, and a fairly dry spring. I did cover the leaves in a layer of mulch, but I think it would have done okay if it didn’t have it. I have a sprinkler hose mounted above the mulch, it doesn’t get every inch but it hasn’t needed to.
It has reduced to about a quarter of the height since I put it together (not what I wanted but I can deal with it. The tomato’s have been productive since late May (in Ohio) when I transplanted them. I have blueberries ripening, Three varieties of tomatoes, peppers, celery, cabbage, ground cherries, beans, cucumbers, squash, Comfrey, and sweet potatoes all growing in this bed. Many from seed, several are transplants
