Full Sun to Partial Shade, protect from Frost in Cooler months.


Water regulary but do not water-log soil. Reduce watering in winter, but never allow the soil to dry out completely. Misting is appreciated spring-fall.


Every two weeks, spring-midautumn, using liquid bonsai food or half-strength general purpose fertilizer. In hot areas, discontinue feeding during the heat of summer. Apply a chelated iron supplement several times yearly.

Leaf and Branch Pruning:

New growth should be pinched, not clipped, several times in spring, when shoots are about 1 inch long, leaving 3-4 clusters of needles. Do major pruning in early fall. Never remove all needles.

Re-potting & Growing Medium:

In general, every 3-4 year in early to mid-spring, before new growth expands, or in early fall. Older specimens (+10 years) may be repotted every 5 years. Prune roots by a 1/3. Use fast-draining soil mix, 1 part Loam, 1 part peat, 1 part sand or alternatively use 1 part Akadama and 1 part Pumice. Protect from full sun for a few weeks after repotting.


Wire between late autumn and winter.
