When I cut them I stick them in a window box type container with soil and they seem to do well and start the sprouting process at the same time. We just started doing strings the other day and trained some to start their climb to greatness.
I need to get something set up for mine to climb. The 2 that made it are looking good. One of them is a couple feet long already. I just have it on a stick for now. I would like to get a few more from you.
