My biggest variegated Jade in a 18in terra cotta pot last year
Pruned in January, unpotted at the beginning of April
Took a saw and cut off 3/4 of the root mass
With most succulents you would let the cuts dry but with Jades you can pot up right away in moist soil, then let sit for a week or two before watering again.
Staged into a 18in bonsai pot, it had to be anchored to the pot with wire since it so top heavy
I will shorten the branches to the red line in the fall
