Plant Cryptomeria in moist, well-drained, slightly acidic soil in full sun or light shade, avoiding exposed windy spots as these can scorch the foliage in winter. Water regularly during the first year to help it establish, especially in dry weather.

Feed in spring with a balanced, slow-release fertiliser if growth is poor or foliage looks pale. Apply a generous layer of mulch around the base of the plant in late winter, keeping it clear of the crown. Pruning isn’t usually needed, but any shoots that spoil the shape can be removed in autumn.
