The Younger Grandson is getting into gardening. I thought he might like square-foot gardening:
When Kris and I bought our first home, we both wanted a vegetable garden, but we didn’t want the drudgery that came with it. Besides, we didn’t have a big space in the country — we had an average city lot. Fortunately, we discovered Mel Bartholomew’s Square-Foot Gardening.
The square-foot gardening concept is simple: Build a raised bed, divide the space into sections of one square-foot each, and then plant vegetables (and/or flowers) in just the amount of space they need. The advantages of this system include reduced workload, less watering, easy weeding (and not much of it), and easy access to your crops. This is a great way to learn to grow some of your own food.
