Western Arborvitae Growing Tips

Light: Prefers full sun but can tolerate partial shade. Full sun promotes denser foliage and healthier growth.

Soil: Adaptable to a range of soil types but thrives best in moist, well-drained, acidic to neutral soil.

Fertilizer: Fertilize in early spring with a balanced, slow-release fertilizer formulated for evergreens. Avoid over-fertilization, which can lead to excessive growth and potential damage.

Pruning: Minimal pruning required. Prune for shaping or size control in late winter or early spring. Avoid heavy pruning into old wood.

Propagation: Typically propagated by semi-hardwood cuttings in late summer.
