American Arborvitae

Where to Plant

• Sunlight: Plant your American Arborvitae where it will receive at least 6 hours of direct sunlight daily for dense, lush growth. It can tolerate partial shade, but too much shade will cause the foliage to become thin and leggy.
• Soil: These trees thrive in rich, well-draining soil that stays consistently moist. If you have heavy clay or sandy soil, amend it generously with compost or organic matter to improve drainage and moisture retention.

Watering Requirements

During the first year, water deeply twice a week to help the root system establish, checking that the soil is moist a few inches down. Once established, American Arborvitae is moderately drought-tolerant, but consistent watering during dry spells prevents browning and keeps the foliage vibrant. Inconsistent watering often leads to sparse growth and premature needle drop.

Pruning Tips

Pruning is best done in early spring before new growth begins to maintain shape and density. Lightly shear the foliage to control size, but avoid cutting back into old wood that has no green needles, as it won't regrow. Regular light pruning keeps the plant tidy and encourages thicker growth, acting like a shape-up rather than a drastic cut.

Fertilizer Needs

Apply a slow-release, balanced evergreen fertilizer in early spring as new growth starts to emerge. Avoid high-nitrogen fertilizers late in the season, as this can push soft new growth that won't have time to harden off before winter frost hits.
