Question
Hi Mike,After lots of reading I like the idea of square foot gardening. I have several hundred cement couplings that are 12 to 18 inches round and 8 to 12 inches deep.My question is,could I take several of these couplings place them side by side fill them with the proper mix and use the principles of square foot?

Answer
Absolutely. Any hard material that stands at least 8" high and holds in the composition of the soil will work. I personally use 10X12 cedar due to its longevity, but cement blocks or couplings will work just fine.

Let me know if you need any other information on square foot gardening. A great book to keep as a reference is "Square Foot Gardening" by Mel Bartholomew. You can find it in paperback at all reputable bookstores.

Good luck, and have a great weekend.

Mike
