chasv77answered grow question 5y 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.
