Creating a formal hedge with arborvitae is an excellent way to add privacy, structure, and beauty to your landscape. Arborvitae, known for its dense foliage and upright growth, is a popular choice for creating elegant, low-maintenance hedges. This guide will walk you through the steps to establish a stunning formal hedge using arborvitae.
Choosing the Right Arborvitae Varieties
Not all arborvitae are suitable for formal hedges. Select varieties that have a narrow, upright growth habit and dense foliage. Some popular choices include:
- Thuja occidentalis ‘Smaragd’
- Thuja occidentalis ‘Emerald Green’
- Thuja plicata ‘Excelsa’
Consider your climate and soil conditions when choosing a variety. Consult with local nurseries to find the best fit for your region.
Preparing the Site
Proper site preparation ensures healthy growth and a beautiful hedge. Follow these steps:
- Choose a location with full sun or partial shade.
- Ensure well-draining soil to prevent root rot.
- Clear the area of weeds, grass, and debris.
- Amend the soil with compost if necessary to improve fertility.
Planting the Arborvitae
Follow these steps for successful planting:
- Dig a trench or individual holes that are twice as wide as the root ball.
- Place the arborvitae in the hole, ensuring the top of the root ball is level with the soil surface.
- Backfill with soil, pressing gently to eliminate air pockets.
- Water thoroughly after planting.
Spacing and Arrangement
To create a dense, formal hedge, space the arborvitae plants appropriately:
- Typically, plant trees 2 to 3 feet apart.
- Adjust spacing based on the mature width of the variety.
- Maintain straight rows for a formal appearance by using stakes and string guides.
Pruning and Maintenance
Regular pruning keeps your hedge neat and encourages dense growth. Follow these tips:
- Begin pruning after the first year to shape the hedge.
- Use sharp hedge shears or pruning tools for clean cuts.
- Trim the sides to maintain a straight, vertical line.
- Top the hedge to the desired height, tapering slightly inward at the top for a formal look.
- Remove any dead or diseased branches promptly.
Watering and Fertilizing
Proper watering and fertilization promote healthy growth:
- Water deeply once a week during dry periods, especially in the first year.
- Apply a balanced, slow-release fertilizer in early spring.
- Mulch around the base to retain moisture and suppress weeds.
Additional Tips for a Perfect Formal Hedge
Achieve a professional look with these extra tips:
- Use a string line and stakes to guide straight cuts.
- Regularly inspect for pests and diseases.
- Adjust pruning as the hedge matures to maintain shape.
- Be patient; a formal hedge takes several years to reach full density and height.
With proper planning and maintenance, your arborvitae hedge will provide years of beauty and privacy, enhancing your landscape with a classic, formal look.
