Cultivation Details
Within its latitudinal and elevational range, Calocedrus rupestris experiences a monsoon tropical climate, with a July-October wet season and annual rainfall of 1,200 - 3,000mm. Temperature is seasonally variable with winter lows cold enough to experience occasional frosts, and summer highs around 35°c[1]. The tree can tolerate frosts, but needs hot summers in order to do so. It is likely to succeed in warm temperate areas with continental climates and mild winters such as southeastern USA[2]. Only found on well-drained limestone soils in the wild[1]. Some living trees are estimated to be 600 - 800 years old[1].
Propagation
Seed - sow early spring in a greenhouse[3]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in a greenhouse or cold frame for their first winter. Plant them out in late spring or early summer, after the last expected frosts and consider giving them some protection from the cold for their first winter outdoors. Cuttings of the current season's growth, taken in mid autumn, in a light sandy soil in a cold frame[3].
