Thuja occidentalis, commonly known as the eastern arborvitae, is a slender evergreen tree indigenous to eastern North America. This low-maintenance species thrives in clay soils, wet environments, and areas affected by black walnut and air pollution. It flourishes best in moist, well-drained loamy soils that are neutral to alkaline. However, it struggles in dry conditions and should be planted away from exposed, windy locations. Full shade should also be avoided, as it can lead to significant thinning of the foliage. The various cultivars typically exhibit growth forms that are globular, pyramidal, columnar, or conical. These trees serve multiple purposes, including as specimen plants, accents, hedges, or foundation plantings.
Regarding pests and diseases, Thuja occidentalis generally faces minimal issues. While leaf miners may occasionally damage the tips of leaves, other pests such as bagworms, mealybugs, scales, and spider mites are infrequent visitors. Canker can sometimes pose a challenge as well. The tree does not thrive in overly shady, dry, or windy conditions and is vulnerable to winter damage, including stem breakage due to ice and snow accumulation. Additionally, in dry and exposed areas, the foliage may suffer from winter burn, resulting in a yellow-brown appearance.
