Planting emerald green arborvitae is a popular choice for homeowners looking to create a lush, vibrant hedge or privacy screen in their yard. This evergreen shrub is admired for its rich green color, dense foliage, and low-maintenance nature. Successfully planting and caring for emerald green arborvitae requires attention to soil preparation, proper spacing, watering, and ongoing maintenance. By understanding the steps involved in planting and nurturing these shrubs, you can ensure they grow healthy and provide long-lasting beauty for your landscape. With patience and care, emerald green arborvitae can transform outdoor spaces with their natural elegance and year-round greenery.
Understanding Emerald Green Arborvitae
Emerald green arborvitae, also known as Thuja occidentalis ‘Smaragd’, is a narrow, columnar evergreen that grows slowly but consistently. It is an ideal choice for hedges, borders, and privacy screens because of its dense growth and ability to maintain a uniform shape. These shrubs can reach heights of 10 to 15 feet and widths of 3 to 4 feet, making them suitable for both small and large gardens. Emerald green arborvitae thrives in full sun to partial shade and is valued for its low-maintenance care and resistance to common pests and diseases.
Benefits of Planting Emerald Green Arborvitae
- Creates a natural privacy screen or windbreak.
- Maintains vibrant green color year-round.
- Requires minimal pruning and maintenance.
- Resistant to deer and other common garden pests.
- Provides a structured and elegant appearance to landscaping.
Choosing the Right Location
Selecting the right location is crucial for the successful growth of emerald green arborvitae. These shrubs prefer full sun for optimal color and growth but can tolerate partial shade. Choose a site with well-draining soil to prevent root rot and ensure the roots establish properly. Avoid low-lying areas that may accumulate excess water or have poor air circulation, as these conditions can increase the risk of disease.
Spacing Considerations
Proper spacing is essential when planting multiple emerald green arborvitae for a hedge or row. Plant the shrubs approximately 3 to 4 feet apart to allow room for growth while maintaining a dense, uniform appearance. Closer spacing may lead to overcrowding, which can reduce airflow and increase susceptibility to disease, while too much distance can create gaps in the hedge.
Preparing the Soil
Soil preparation is a critical step to ensure your emerald green arborvitae thrive. These shrubs prefer slightly acidic to neutral soil with good fertility. Before planting, test the soil pH and adjust as needed to create an optimal growing environment.
Steps to Prepare the Soil
- Remove weeds, rocks, and debris from the planting area.
- Loosen the soil to a depth of about 12 to 15 inches to promote root growth.
- Incorporate organic matter, such as compost or well-rotted manure, to improve soil structure and fertility.
- Ensure the soil is well-draining; if necessary, amend with sand or perlite to enhance drainage.
Planting Emerald Green Arborvitae
Once the soil is prepared, planting can begin. Proper planting technique ensures the roots establish quickly and the shrub grows strong and healthy.
Step 1 Digging the Hole
Dig a hole that is approximately twice the width of the root ball and slightly shallower than the height of the root ball. This encourages roots to grow outward rather than downward and prevents settling that may bury the base of the shrub too deeply.
Step 2 Placing the Shrub
Carefully remove the arborvitae from its container and gently loosen any circling roots. Place the shrub in the center of the hole, making sure the top of the root ball is level with the surrounding soil. Backfill with prepared soil, lightly firming it around the roots to eliminate air pockets.
Step 3 Watering and Mulching
Immediately water the newly planted arborvitae to help settle the soil and provide moisture to the roots. Apply a 2 to 3-inch layer of mulch around the base, keeping it a few inches away from the trunk to prevent rot. Mulch helps retain moisture, regulate soil temperature, and reduce weed growth.
Watering and Maintenance
Proper watering and ongoing maintenance are key to the successful growth of emerald green arborvitae. These shrubs require consistent care, especially during the first few years after planting, to establish strong roots and maintain their vibrant appearance.
Watering Guidelines
- Water newly planted arborvitae deeply and regularly during the first growing season.
- Reduce watering frequency as the shrub establishes, but ensure deep watering during dry spells.
- Avoid overwatering, which can cause root rot and other problems.
Fertilization
Fertilize emerald green arborvitae in early spring with a balanced, slow-release fertilizer formulated for evergreens. Avoid over-fertilizing, as excessive nutrients can lead to weak growth and increased susceptibility to pests.
Pruning and Shaping
Minimal pruning is needed for emerald green arborvitae, but occasional trimming helps maintain shape and encourages dense growth. Prune in late spring or early summer, cutting back any dead or overgrown branches. Avoid heavy pruning into old wood, as arborvitae may not regenerate from mature, brown branches.
Protecting Your Arborvitae
Emerald green arborvitae are relatively hardy, but protecting them from harsh conditions ensures long-term health and vibrancy.
Winter Care
Protect shrubs from heavy snow or ice accumulation by gently brushing off snow to prevent branch breakage. In extremely cold regions, burlap wraps or windbreaks can shield young plants from desiccation and freezing winds.
Pest and Disease Control
Monitor for common pests such as spider mites or bagworms, which can damage foliage. Use horticultural oils or insecticidal treatments as needed. Proper spacing, airflow, and watering practices reduce the likelihood of fungal diseases and other issues.
Planting emerald green arborvitae involves careful site selection, soil preparation, proper planting techniques, and consistent maintenance. By choosing the right location, spacing shrubs correctly, providing adequate water and nutrients, and protecting them from environmental stresses, you can ensure healthy growth and vibrant color year-round. These evergreens are an excellent addition to any landscape, offering privacy, structure, and a touch of natural elegance. With patience, attention to detail, and regular care, your emerald green arborvitae can thrive for many years, creating a stunning visual impact and enhancing the beauty of your outdoor space.
