It's not ideal of course. Can you tie the branches higher up to pull it back together, or at least make sure it doesn't pull apart any further? I'd probably consider taping off the wound too, just to keep it dry and clean until she finishes. You don't want her wasting time on repair when she could be building bud.
Seems to be pretty damp in there as well, why's that?
I've had this happen before too Snid... more than once. I just made a band-aid out of masking tape and all was good again.
