I'm in the process of putting together a frame to hold a series of hanging gardens (assorted vegetables and fruits and need to come up with something that will handle the weight load without too much difficulty. We currently have these hanging from an eave of a utility shed, but are not getting good sunlight in that area and I don't think the wood used for the shed is enough to hold the total number of plants anyway.
I've come up with a simple plan that I think will be sufficient for our needs and will be located in an open area of our backyard on cement slab. I'll be building it out of pressure treated 2x4s and decking screws and the unit measures 96 inches high (4 vertical 2x4s) and roughly 48inches square.
Each of the planters weighs between 20-30 lbs depending on dirt load and plant, and hangs from a heavy-duty eye-hook screwed into the frame.
I'm concerned it may be top-heavy, but am assuming that the 2x4s are sufficient to hold the load.
My biggest question is should I be looking at something more like an A-Frame approach or is this 'box' frame sufficient?
Do I need to worry about mounting this in some fashion to the ground?
Here's a mockup:
