Thuja occidentalis ‘Woodwardii’ is a well-known cultivar of the Eastern Arborvitae, notable for its distinct growth pattern and landscape value.

Thuja occidentalis ‘Woodwardii’: An In-depth Look

‘Woodwardii’ is characterized by its globular, almost spherical shape, and dense, soft, green foliage. Unlike the typical pyramidal Arborvitae, it forms a naturally rounded shape without the need for pruning.

Native: Thuja occidentalis is native to North America. It is predominantly found in the northeastern United States and southeastern Canada. This species naturally occurs in wet forests, swamps, and along lake shores, thriving in cool, moist, well-drained environments.

Plant Type and Habit: It is an evergreen conifer with a compact globular-spreading growth habit. This distinct form sets it apart from other Arborvitae cultivars.

Size: Grows to a notable size of 4-10 feet tall (1.2 to 3 meters) and 8-15 feet wide (2.4 to 4.5 meters), it’s perfect for creating visual impact in larger landscape spaces.

Foliage: The foliage is a rich, lush green, maintaining its vibrant color throughout the year. The leaves are scale-like and densely packed, giving the plant a full, textured appearance.

Bark: The bark is reddish-brown, relatively smooth, and becomes more textured with age.

Uses: Excellent choice for use in spacious garden designs, hedges, foundation plantings, and as an eye-catching specimen plant.

Hardiness: Hardy in USDA zones 3-7, it can withstand cold winters and a range of environmental conditions.

Wildlife: American arborvitae provides nesting sites for songbirds, as well as cover, especially in the winter, for deer, which both feed on the branches and use them for shelter from the cold.

Toxicity: Generally considered non-toxic to humans and animals.

Deer and Rabbit: May suffer some damage from deer and rabbits, especially in areas where these animals are prevalent.

Invasiveness: This cultivar is not considered invasive and typically stays within its planted boundaries.

Benefits: Offers robust year-round greenery with its dense, lush foliage and unique globular shape. Hardy and low-maintenance, Woodwardii is adaptable to various soils, provides wildlife shelter, and is effective in urban pollution absorption.

American Arborvitae Growing Tips

Light: Thrives in full sun but can also grow well in partial shade. Full sun exposure leads to denser foliage growth. Usually appreciates some light afternoon shade in hot summer climates. Protect from drying winds, especially when young.

Soil: Adaptable to a wide range of soils but prefers moist, well-drained, slightly acidic to neutral soil. Tolerates clay soils.

Water: Regular watering is important, especially for young plants and in dry conditions. Avoid extreme dry soil in the fall, which can cause the evergreen foliage to dry out in winter.

Fertilizer: Apply a balanced, slow-release fertilizer in early spring. Over-fertilization can harm the plant, so follow the recommended rates.

Pruning: Little to no pruning is required. Prune for shaping or size control in late winter or early spring before new growth starts. Avoid heavy pruning.

Mulch: Provide a generous root zone mulch.

Propagation: Propagated through semi-hardwood cuttings in late summer.

Pests and Diseases: Watch for bagworms, spider mites, mealybugs, and scale insects. Leaf tips may suffer damage from leaf miners. Canker can sometimes pose a problem. Fungal diseases like root rot can occur in poorly drained soils. Good air circulation and proper planting depth help prevent these issues.
