I haven't messed with it yet, it's 300+ sq ft, i didn't measure just guestimated.
I'll put in my 2015 glog when i figure it out.
but just doing the math, a 1.5 ft square gives you 2.2 sq ft per plant and leaves you a little walking room.
I will be watching. I had 10 plants in a row with about 24 feet of garden space(length) and it looked like a hedge by years end. Definitely got tough harvesting towards the end of the summer.
