Pole beans winding around each other.
I've never grown pole beans before, so got 3 plants & 2 metal trellis's. It didn't take long & they were shooting up & gripping onto the trellis. Looking at them closely, I see that they are all wound around each other, braided and what looks like knotted. How can they wind around each other & not choke the life out of each other. I know some of you are reading this and rolling your eyes or laughing. At first I didn't think I would get any flowers since I planted these a month ago & only vines. The person at the garden center says they take a good 60 days. Within the last few days, I am seeing flowers & the little nodules that turn into flowers in various places all over the vines, hidden and out in the open. It should be like a scavenger hunt finding beans, but about the winding around themselves--normal? Thanks.
