Tilling the soil ever year was a pretty tiresome process. So I was looking for an easier way to grow vegetables and came across this book describing another way called Square Foot Gardening. The ideas in this book seem to be pretty good. Use no soil, just use a mix of compost, peat moss and vermiculite. At first I found out that vermiculite is almost impossible to find here in northern Virginia. After searching for a day or so I eventually found it locally.
