Full Sun to Partial Shade. Protect from hard frost especially if pots are likely to freeze.


Needs lots of water. Water everyday during the growing season, and maybe even twice a day during hotter driers summers months. Do not let pot dry out but also do not let pot water log.


To retain and produce small leaves, do not feed high nitrogen fast-acting fertilizers. Feeding three times a year is sufficient to maintain good color and healthy growth without enlarging the size of the leaves.

Leaf and Branch Pruning:

Prune new shoots to 2 leafs, during spring. Between June and mid summer a more robust pruning can be carried out.

Re-potting & Growing Medium:

Every year in younger plants. 3-4 years for older plants or when pots get root bound. Use a well drained growing medium, use larger pots as they have heavy roots.


While most shaping can be done through pruning. If necessary Wiring can be carried out during Mid Summer. Beware as bark is thin and scars easily.
