Arborvitae hedges are a popular choice for creating privacy screens and adding greenery to landscapes. Achieving a lush, bushy growth requires proper care and maintenance practices. This guide provides effective tips to encourage dense, healthy growth in your arborvitae hedges.
Choosing the Right Arborvitae Variety
Selecting the appropriate arborvitae variety is crucial for bushy growth. Some varieties naturally develop fuller, denser foliage. Popular dense-growing options include Green Giant, Emerald Green, and Hetz Midget. Consider your climate and space when choosing a variety to ensure optimal growth conditions.
Planting and Spacing
Proper planting techniques set the foundation for bushy growth. Space plants adequately—typically 2 to 3 feet apart—to allow for full development and air circulation. Planting at the correct depth and in well-draining soil promotes healthy root growth and overall density.
Soil Preparation
Ensure the soil is rich in organic matter and has a pH between 6.0 and 8.0. Amend poor soil with compost or peat moss to improve fertility and drainage. Healthy soil encourages vigorous, bushy growth.
Watering and Mulching
Consistent watering is essential, especially during dry periods. Keep the soil moist but not waterlogged. Apply a 2-3 inch layer of mulch around the base to conserve moisture, regulate soil temperature, and suppress weeds. Mulching also promotes dense foliage.
Pruning for Bushiness
Pruning stimulates new growth and helps maintain a dense, bushy appearance. Begin pruning in early spring before new growth starts. Remove any dead, damaged, or crossing branches. Lightly trim the tips of the branches to encourage lateral growth and fullness.
Pruning Tips
- Use clean, sharp pruning shears.
- Make cuts just above a leaf node or branch junction.
- Avoid heavy pruning, which can stress the plant.
- Repeat pruning annually for best results.
Fertilizing for Dense Growth
Feed your arborvitae with a balanced, slow-release fertilizer in early spring. A fertilizer with nitrogen promotes lush, green foliage and vigorous growth. Follow the manufacturer’s instructions for application rates and timing.
Additional Tips for Bushy Growth
Other practices that support bushy growth include:
- Ensuring adequate sunlight—at least 6 hours of direct sunlight daily.
- Controlling pests and diseases promptly.
- Providing consistent watering, especially during hot, dry weather.
- Monitoring growth and adjusting pruning as needed.
With proper care, your arborvitae hedge will develop into a dense, lush barrier that enhances your landscape and provides privacy. Regular maintenance and attentive watering, fertilizing, and pruning are key to achieving the bushy growth you desire.
