I know this is an old thread, but I just found it
Ron, I have a question about the wiring-do you just cut it off when it starts to bite into the trunks? Be hard to tell if they were rooted if theyre all hooked together without untying them...
Looks like a great idea! I didn't do any securing on a small forest of cuttings I did, and nowthe trees are leaning everywhere... (oops).. So guess what I'll try next time?
