Planting Arborvitae: A Comprehensive Guide
If you’re considering adding the graceful presence of arborvitae trees to your landscape, understanding the proper planting techniques is paramount. Their evergreen foliage and year-round appeal make them a popular choice for homeowners seeking privacy, definition, and aesthetic charm.
Optimal Spacing
- For Green Giant Arborvitae: Allow 4-6 feet of spacing between plants to provide ample room for their rapid growth habit.
- For Other Arborvitae Cultivars: 3-5 feet of spacing is generally sufficient, ensuring adequate airflow and light penetration.
Planting Depth
- Dig a hole twice as wide as the root ball and just as deep.
- The top of the root ball should be level with the surrounding soil.
- Avoid planting too deeply, which can suffocate the roots and inhibit growth.
Hole Size
- The diameter of the planting hole should accommodate the full width of the root ball.
- Creating a hole that is too large can lead to settling and soil compaction, impacting the tree’s stability.
- In rocky or compacted soils, dig a larger hole to loosen the surrounding soil and facilitate root expansion.
Planting Procedure
- Prepare the Hole: Dig the hole according to the guidelines above, amending the soil with organic matter for improved drainage and nutrient availability.
- Remove the Tree from the Container: Carefully remove the arborvitae from its container, gently loosening any circling roots.
- Place the Tree in the Hole: Set the root ball in the center of the hole, ensuring it is level with the surrounding soil. Backfill with soil, gently tamping down to remove air pockets.
- Water Thoroughly: Water deeply and slowly after planting to settle the soil and hydrate the roots.
- Mulch: Spread a 2-3 inch layer of mulch around the base of the tree to retain moisture, suppress weeds, and insulate the roots.

Growing Conditions for Arborvitae
Understanding the optimal growing conditions for your Arborvitae plants is crucial for their success and longevity in your landscape. These evergreen beauties require specific care to thrive. Let’s dive into each factor that contributes to their well-being.
Hardiness Zone
Arborvitae are hardy trees that can withstand cold temperatures. They fall within USDA hardiness zones 3 to 8. This means they can tolerate winter lows ranging from -40°F to 20°F, making them suitable for a wide range of climates.
Soil Type
Arborvitae prefer well-drained soils that are moist but not waterlogged. Ideal soil types include loam, sandy loam, or clay loam. It’s also essential to ensure a soil pH between 5.0 and 6.5, which is slightly acidic to neutral.
Sunlight Requirements
Most arborvitae varieties thrive in full sun to partial shade. They need at least 6 hours of direct sunlight per day to maintain their compact shape and vibrant color. However, avoid planting them in areas with intense afternoon sun, as this can scorch their foliage.
Watering and Fertilization
Regular watering is crucial for arborvitae, especially during the first year after planting. Once established, water deeply and infrequently, allowing the soil to dry out slightly between waterings. Mulching around the base of the trees helps retain moisture and suppress weeds.
Fertilize arborvitae twice a year using a balanced fertilizer. Apply once in early spring and again in late fall. Avoid over-fertilizing, as this can lead to excessive growth and reduce cold hardiness.
Maintenance of Arborvitae: Keeping Your Evergreens Thriving
Maintaining your arborvitae is crucial to ensure their health, beauty, and lifespan. One key aspect of maintenance is proper pruning, which helps shape your plants, control their growth, and promote their overall well-being.
When to Prune Arborvitae
The ideal time to prune arborvitae is during the late winter or early spring. This is when the plants are dormant and less susceptible to damage. Avoid pruning in the late fall or winter, as the wounds may not heal properly before the onset of cold weather.
How to Prune Arborvitae
-
Remove Dead or Diseased Branches: First, eliminate any dead or diseased branches to prevent the spread of infection. Cut these branches back to the main trunk or the next healthy branch.
-
Shape the Tree: Use sharp, clean pruning shears to shape your arborvitae. Cut in a diagonal line facing the direction you want the branch to grow or to remove excess growth.
-
Control Height: If you wish to control the height of your arborvitae, prune the upper branches back to a desired length. Be careful not to remove more than one-third of the tree’s height at any one time.
-
Encourage Density: To create a denser appearance, prune the side branches by about one-third or less of their length. This encourages the growth of new shoots and fills in the gaps.
-
Avoid Over-Pruning: Arborvitae do not tolerate severe pruning well. Never remove more than one-third of the tree’s branches or foliage at a time. Over-pruning can weaken the plant and make it more susceptible to pests and diseases.
Additional Considerations for Arborvitae Care and Landscaping
Landscaping with Arborvitae:
Arborvitae’s dense foliage and pyramidal shape make them ideal for creating privacy screens, windbreaks, and focal points in your landscape. Plant them in rows or clusters to form dramatic hedges or use them as specimens to add structure and interest. Their evergreen nature ensures year-round beauty, making them a versatile addition to any landscape design.
Finding a Reliable Nursery:
When selecting arborvitae plants, it’s crucial to find a reputable nursery. Look for nurseries that specialize in ornamental trees and shrubs and have a good track record of providing healthy plants. Inspect the plants thoroughly before purchasing, ensuring they are free of pests or diseases and have a well-developed root system.
Tips for Purchase and Care:
- Choose plants that are the appropriate size for your planting site.
- Dig a generous planting hole and amend the soil with compost or peat moss to improve drainage and fertility.
- Water deeply after planting and mulch around the base to conserve moisture and suppress weeds.
- Regular watering is essential, especially during the first year after planting.
- Fertilize arborvitae annually in spring with a balanced fertilizer.
