Standing 12- to 14-feet high and 3- to 4-feet wide when mature, Emerald Green arborvitae has vivid green foliage even in the depth of winter. Once a young Emerald Green plant's root system is established, it will grow from 6 to 9 inches annually.

Care For An Emerald Green Arborvitae

Emerald Green Arborvitae (Thuja occidentalis 'Smaragd') is a fuss-free tree. In warmer zones, the tree may not grow well. Also called Emerald Green Cedar and ‘Smaragd’ American Arborvitae, Emerald Green Arborvitae grows best in well-drained, neutral or alkaline, moist loam soils and in spots that are sheltered from strong winds. Emerald Green Arborvitae thrives in areas that experience regular rainfall. Space trees for a hedge 18 to 24 inches apart or a single tree 3 to 4 feet from other trees, shrubs, walls or fences. Leave a 6-inch space around the trunk and spread the mulch up to the tree's drip line. Prune an Emerald Green Arborvitae before new growth appears in early spring, wiping the blades of your pruning shears with rubbing alcohol before and after trimming the tree to help prevent the spread of diseases and pests.
