In pruning most other needled and broadleaf evergreens, cuts can be made at any point along the branch, but care should be taken not to cut too far back into the older wood. New growth is not as readily produced from old wood. Cut away any dead, damaged, or diseased branches in late winter
Long Term:
Winter:
Late winter/early spring:clear old dead foliage before new spring growth
Spring:
Late winter/early spring before new spring growth, prune out upright shoots to maintain globose form
Summer:
Dead, diseased, and broken wood can be removed at any time of year. However, for general pruning the best time is in late winter or early spring just before growth begins
Fall:
Dead, diseased, and broken wood can be removed at any time of year. However, for general pruning the best time is in late winter or early spring just before growth begins
General Care Comments:
Give full sun, water deeply during long dry spells, water at base of plant, avoid wet soils, do not overcrowd, can trim back soft new growth in early spring
