I'm going to try pole beans for the first time this year. Always used bush beans in the past. I'm with a community garden that use 10 x 4 foot raised beds. So thinking of setting up a double row of Kentucky Wonder at the north end of one bed, with metal electrical conduit as the support.
I'll use 1/2 inch conduit. Since it available in 10 foot sections, I'm thinking of using two, bend a 2 foot leg on each, and then use a coupler to join the two for a U-shape that just under 8 feet tall and 4 feet wide. If I drove the vertical legs about a foot into the ground and then use some wire for additional support, do you think it will work? Is it reasonable to expect poles to grow 7+ feet in the North Florida heat?
Any suggestions for trellis material for the vines to climb? Would they climb string draped from horizontal bar of the conduit?
