chee_52answered grow question 3 years ago I've used duct tape in the past to help cover and secure wounds like this, but it may also be helpful to loosen the wire on that side a bit before applying anything (if there's still a little give or movement in the stem).
Just a side question: do you have any wire with a softer rubber or foam coating? It looks like the wire you're using might start cutting into the stem's surface if the tension is too high.
Good luck! I think she'll make a strong recovery!
