Position Outdoor tree only. Partial shade, particularly in Summer.
Repotting Every two years in Spring as new growth starts, use a basic soil mix.
Pruning Hemlocks grow very slowly and as new growth is similar in colour to mature foliage (except Tsuga heterophylla) growth extension can grow unnoticed and trees can easily get out of shape. Cut back fresh growth as it extends to produce a more compact second flush of growth and back budding from the base of old needles.
Propagation Sow seed outside in Spring. Root semi-ripe cuttings in late Summer or early Autumn.
Pests and Diseases Largely trouble free.
