Description

Green Mountain Boxwood is noted for its dense, upright pyramidal shape that tends to fill out right to the ground, and its winter hardiness. It  can easily be shaped into a formal hedge and sometimes seen pruned to a decorative spiral-shaped topiary.

This cone shaped shrub or small tree grows best in a mixture of sand/clay soil and receiving both sun and shade. 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.

This plant 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. 

Insects, Diseases and Other Plant Problems: 

Moderately susceptible to boxwood blight. Root rot can also be a issue in wet locations.  Insects effecting boxwood include boxwood leaf miner, boxwood mite and boxwood psyllid.   Nematodes are an issue in the deep south.
