SG--I used the wood you should not. PT. It was an after thought after I completed. So I did add weed barrier that seems to help. Veggies still seem to do fine, if I were to do it again I would use Cedar.

yes Brant the Taters are fun. I cannot recall the type I planted last season, but everytime I dug in I would get enough for a dinner for the 3 of us.

This is the theory of the square foot gardening-This was passed onto me from another fish head. If you are limited on space this works well.

Also, plan before you plant some veggies grow better when planted together and some do not do well. JCoho advised me on that.
