In the electric co-op magazine a few months ago, there was an article about keyhole gardens. They are an African design that are supposed to conserve water. Since we had all the material we needed to build one, we thought it would be fun to give it a whirl.
Dimensions are supposed to be a five foot circle that is three feet tall. Use any material you happen to have. Ours was a pallet of brick left over from building our home. You do need to take a wedge out of the circle. At the center, place a 1 foot wide and 4 foot tall cylinder of chicken wire.
Now you're ready to plant. This is my
husband's project and he chose tomatoes. After all, you can't have too many home grown tomatoes. You are supposed to just water this garden through the wire cylinder.
