Calluses can be bulky so reduce wounds properly. For ramification, pinch new growth back to 2 leaves after 4 or 5 have formed during the spring. Guy-wires are quite useful with this species. Know that wired branches tend to lose vigor so don't pinch back growth too much on a wired branch. You can be ruthless in cutting back the roots.
Early spring is best, but they do well with a fall repot, too.
In their native range, they have few pest problems. The worst are caterpillars that can destroy the foliage in very short order. Look the trees over each day, especially the underside of the leaves, for these pests. The Bonsai Site . All Rights Reserved.
