Growth Rate
Moderate: Arborvitae generally has a moderate growth rate, typically growing about 6 to 12 inches per year once established. The growth rate can vary depending on factors such as climate, soil conditions, and care.
Size
Mature Height: Arborvitae hedges can reach varying heights depending on the specific cultivar and pruning habits. They typically range from 10 to 20 feet tall.
Mature Spread: They have a spread of about 3 to 6 feet, forming a dense, columnar shape ideal for hedges.
Growing Conditions
Sunlight: Thrives in full sun to partial shade. Full sun exposure usually results in denser growth.
Soil: Prefers well-drained soil but can tolerate a range of soil types, including clay and sandy soils.
Watering: Regular watering is necessary, especially during the establishment phase. Once established, they are moderately drought-tolerant but benefit from occasional watering during dry spells.
Hardiness Zones: Suitable for USDA hardiness zones 2-7, depending on the cultivar.
Maintenance
Pruning: Regular pruning helps maintain shape and density, especially for hedging purposes. Early spring is generally the best time for pruning.
