chasv77answered grow question 5 years ago Be careful with how tight you tie your strings.
If you forget about them, the stems will grow around it, literally swallowing them, and you may choke off a little of that transport to the rest of the stem.
I would use the twisty tie stuff that comes on a reel, double it up near the end of the tie, shaped as a hook.
That will allow the stem to grow and expand, while spreading out the hook part.
