Nice to see other people trying this species!
In one of the pics on previous page some leafes show deficiency, mine does that every year when it starts producing flower buds it will dissapear in a couple of days after feeding magnesium or epson salt.
The big wounds do close slowely given there is growth above the wounds
@leatherback i am sure i already showed you pictures of that somewere
Also another 2 cents is keep on removing growth in the crotches if you dont it will result in a ugly knob at the branch base.
Eddit:
Heres a picture of the callus rolling in after a season of growth
It only started healing after i grinded the stump i left into this propper wound.
