Worth saving / where to cut?
Hi, I'm hoping for advice if it is still worth investing time and energy in my sad Calamansi.
The story behind this: although in a winter tent it caught frost last November but held up pretty well afterwards. Bought a proper heater and had no issues with frost anymore.
Anyway, some damage was already done, pruned it back and waited for spring. Over time the bark split open at some points (first and second picture) but at the same time it has now started new growth beyond those points as well (third picture). It even started forming buds.
Should I prune it back until the point where the bark is still intact, should I only prune the obvious dead parts or is it just a slow death of the whole plant that I'm witnissing and should just end it?
Any advice is appreciated!
