We’re doing the square foot gardening, too. However, we’re on a hillside so there is quite a slope. Nothing can be easy for my husband! He’s having to do a terrace of sorts and only has one 4x8 bed complete with the second one almost done. We eventually want to have at least 16 of them but are hoping to do 4 this year. I need to plant a money tree so we can have it all at once! :0) I’m not very patient.
