Cultivation
- Plant 'Emerald Green' arborvitae in moderately moist, well-drained soil in a full sun to partial shade location. In warmer climates, some shade is preferable. It should not be planted in full shade since this greatly reduces the density of the foliage. Avoid exposed, windy locations, especially in colder climates. Fall is generally the best time to...
Culture
- Soil needs to be kept moist but not soggy; apply a thick layer of compost or mulch over the root zone each year to preserve soil moisture. Feeding is usually not necessary with these plants.
Prevention
- Heavy snow can break branches, so brushing off heavy snows is a good idea. Broken limbs should be pruned off, and the plants may need to be staked upright until they recover.
Habitat
- Plant arborvitae in moist but well-drained soil that is neutral to alkaline in pH. These shrubs do not like to have their roots in soggy soil.
Climate
- 'Emerald Green' arborvitae does better in cooler, dryer climates. In very humid conditions, fungal diseases can be a problem. Improving air circulation can prevent the fungal problems.

Symptoms
- The foliage may turn yellow-brown with winter burn in exposed sites, especially in the northern extreme of the hardiness range. The branches are susceptible to breakage from ice and snow.
