Spacing of boxes with trellises
I'm adding boxes this year and I'm trying to figure out how close I can space my boxes without the trellis of the southern box shading the first row(s) of the box north of it. Overview: I have a 2x8 box running East-West with trellis on the north side. South of this box in another 2x8 that will also have a trellis on the north side of it. Trellises are 6ft tall. In the sake of saving space, I'd like to space the boxes as close as possible without causing shade problems. Anybody with a similar setup?
