I'm about to construct a 4ft wide x 16ft long raised bed, 6" height, for planting blueberries. The space where this bed is going has a chain link fence on the back and one end, although I can walk around to the other side to pick fruits.
How close together can I place the bushes so that density is maximized, but they aren't overcrowded?
I could make the bed 5ft wide if necessary. I was thinking of using some type of zigzag pattern but I also don't know how close to the edge of the raised bed the blueberry can go?
