Ok, so we have 30 feet one direction. How about the other direction? How many feet for that?
Went out and measured - about 21 feet wide. So, it's 30 x 21. I have the largest garden in this group of townhomes. That was accidental but I'm surely glad I have enough to do something.
Within that 30 feet deep outside, there is a deck going out the back sliding glass doors, then step up onto another deck that is large. There is not much actual dirt from the end of that deck to the back wall. There is a brick drainage the width of the garden 19 inches across at the end of that deck. I call that my Riverwalk (like San Antonio has) and from there is 5 feet, 7 inches of actual dirt. It curves forward on each end so it is maybe one foot deeper on each of those two ends. I hope that makes sense so you can mentally see what I'm working with.
