Buxus sempervirens 'Suffruticosa'

Buxus sempervirens grows in evenly moist, well-drained loams (e.g., sand-clay mixture) in full sun to part shade. This plant can grow in close to full shade, but are less vigorous and will have decreased foilage.  Growing in full sun is likely to cause the foliage to scorch in winter or bring on mite attacks.

Plants grown in full shade will be less than desired, having decreased foliage. On the other hand, when growing in full sun, the foliage may scorch, turn brown in winter and suffer from mite attacks. Morning sun is best.

'Suffruticosa' is tolerant of pruning, however, pruning should be done after the last frost. Pruning will lead to tender new shoots, which can be damaged by a late frost. Its shallow roots should be protected with a layer of mulch. Limit cultivation around these shallow roots, it can damage the plant. Location and maintenance of this plant can have an effect on its health. Protect from winds and full winter sun by placing in a location where these conditions are limited. Winter winds can cause dehydration and bronzing. Remove any accumulated snow to protect the branches. Thinning plants annually will assist with air circulation.
