I am getting ready to build a 3 tiered pyramid for my strawberry plants. Should I plant all of my strawberries and the 3 sides of the direct sun? I'm afraid if I plant on the back side of the pyramid those plants won't get enough sun. If anyone has had success or otherwise, please advise. I'm only experienced in growing mostly small trees and this is the first time for strawberries. I want to succeed because they are my wife's favorite.
