Whoa!
I think it will survive, but it likely will need a severe cut back below the gnawing on the trunk.
If you feel lucky just trim and cut paste, yet if it were me, the pruning shears and cut paste would out in a jiff!
That’s a pretty thorough gnawing for either a rat or a rabbit. Almost looks like a dog like varmint chewing the trunk and branches.
Wondering what other kind of varmints there are in Romania near you?
Its pretty obvious some critter is taking a liking to this species, so devise a safe storage plan from here on.
Over here I discovered I can’t keep a young azalea growing out without it being screened in or the rabbits will have a free for all on the foliage, sometimes trimming them to a couple inches off the ground.
Sorry,
