I have a Kalamansi (aka Calamondin) in a 20" planter that’s approximately 10 years old. Considering I’ve had this plant for over a decade, I know embarrassingly little about how to care for it. Every year, I put it outside for the summer, and then bring it back inside in the Fall. I fertilize every 6 months with osmocote, and I root-prune or add potting mix every two-ish years. That’s about it.
This year, when I brought it back inside for the Fall (just before Halloween), I noticed that a large portion of the bark was diseased. There was what appeared to be almost an abscess in the bark, and a large portion of bark around the abscess was black and dead. So, I cut away as much of the black/dead bark as I could, and then used hydrogen peroxide on the wound. But, I have no idea if I did the right thing or not, because the wound is really big, and I’m nervous that I just doomed my Kalamansi.
Here are some pictures of my Kalamansi, post-surgery (FYI, a bunch of leaves dropped after I brought it inside, but that happens every year, so I’m not too worried about that):
What should I do next?
- Nothing, cause I’ve already done enough, and the plant needs time to rejuvenate?
- Cut the whole thing off below the wound, and let new shoots and branches grow up from the stub?
- Try to bridge-graft the wound? (In which case, when is the best timing for that, and can I just use some of the green branches stripped of leaves for the scion?)
- Just buy a new Kalamansi, cause this one’s doomed?
Any advise or expertise would be much appreciated!
