If you have limited space for your Square Foot Garden here is an idea that I am experimenting with. It is working. However getting the rain barrel water to the garden is something that I have yet to figure out.
The roof is hot and cucumbers like warmth, perfect.
Mel’s Mix is light so weight has not been a problem supporting the box. The garden is a three by two feet space. We are getting beautiful cucumbers for our salads on a consistent basis.
