They will grow especially well in swampy areas and in alkaline soil. Hardy in zones three through seven, the emerald green arborvitae prefers full sun to thrive.
They will perform best in an area with high atmospheric moisture.
Emerald green arborvitae, or ‘Thuja occidentalis,’ makes an excellent hedge plant.
They are also much easier to propagate than most other plants. Propagation can be done best from cuttings.
It is possible to tear an emerald green arborvitae apart and make literally hundreds of cuttings that will grow into full sized plants.
Emerald arborvitae can be pruned early in the season, prior to new growth. This is often not needed, however, because the plants often grow naturally into a perfect pyramidal shape.
If the winter is especially cold, the foliage of an emerald green arborvitae will turn yellow-brown.
