How To Plant An Arborvitae Emerald Green – For A Perfect Privacy Hedge

Dreaming of a lush, vibrant green privacy screen that stands tall and elegant year-round? The ‘Emerald Green’ Arborvitae (Thuja occidentalis ‘Emerald Green’) is often the first plant that comes to mind for good reason.

Its narrow, pyramidal growth habit and rich, evergreen foliage make it a landscaping staple, perfect for creating living fences, accentuating garden beds, or adding architectural interest.

While these beautiful evergreens are relatively low-maintenance once established, getting them off to a strong start is crucial for their long-term health and your landscaping success. This comprehensive guide will walk you through every step of how to plant an arborvitae emerald green, ensuring your investment thrives.

Laying the Groundwork: Site Selection and Soil Preparation

Before you even think about digging, careful planning makes all the difference. Choosing the right location and preparing the soil correctly are foundational steps for a healthy ‘Emerald Green’ Arborvitae.

Choosing the Perfect Spot

Site selection is paramount for ‘Emerald Green’ Arborvitae. These plants thrive in specific conditions that mimic their natural habitat.

• Sunlight: ‘Emerald Green’ Arborvitae prefers at least 6 hours of full sun daily. While they can tolerate partial shade, too little sun can lead to sparse growth and a less vibrant green color.
• Drainage: Good drainage is non-negotiable. Arborvitae hate “wet feet,” which can quickly lead to root rot. Observe your chosen spot after a heavy rain; if water pools for more than an hour, consider another location or amend the soil significantly.
• Space: Consider the mature size. ‘Emerald Green’ typically grows 10-15 feet tall and 3-4 feet wide. Plant them at least 3 feet apart for a dense hedge, or further apart if you want individual specimens.
• Proximity to Structures: Keep them a safe distance from foundations, fences, and utility lines to allow for root growth and air circulation.

Understanding Your Soil

Healthy soil is the bedrock of healthy plants. Taking a few minutes to understand your soil composition will pay dividends.

• Soil Test: A professional soil test is highly recommended. It will tell you your soil’s pH and nutrient levels, guiding any necessary amendments. ‘Emerald Green’ Arborvitae prefers slightly acidic to neutral soil (pH 6.0-7.0).
• Drainage Test (Perk Test): Dig a hole about 12 inches deep and fill it with water. If the water drains within 10-15 minutes, your drainage is good. If it takes longer, you’ll need to amend the soil to improve drainage.
• Amending Heavy Clay Soil: If you have dense clay, incorporate plenty of organic matter like compost, aged manure, or peat moss. This improves aeration and drainage.
• Improving Sandy Soil: Sandy soil drains too quickly and struggles to retain nutrients. Adding organic matter will help it hold moisture and essential nutrients.

Selecting Your ‘Emerald Green’ Arborvitae

When you’re ready to purchase your plants, a discerning eye will help you choose healthy specimens that are ready to thrive.

• Foliage: Look for plants with vibrant, uniform green foliage. Avoid any with yellowing, browning, or sparse patches, which can indicate stress or disease.
• Branch Structure: Choose plants with a strong central leader and well-spaced branches. Gently check for any broken or damaged limbs.
• Root Ball: If possible, gently slide the plant out of its container to inspect the roots. They should be firm, light-colored, and not overly circling or matted. Avoid plants with roots growing out of the bottom drainage holes excessively.
• Size: Select plants appropriate for your budget and immediate needs. Younger plants are often more affordable and adapt quicker, while larger specimens provide instant impact.

Mastering how to plant an arborvitae emerald green: A Step-by-Step Guide

Now that you’ve prepared your site and selected your plants, it’s time for the main event. Follow these steps precisely to ensure your ‘Emerald Green’ Arborvitae gets the best possible start.

Step 1: Digging the Perfect Hole

The size and shape of your planting hole are critical. It’s often said that you should “dig a $100 hole for a $10 plant,” and for good reason.

• Width is Key: Dig a hole that is two to three times wider than the root ball. This allows the roots ample space to spread into the loosened soil, promoting faster establishment.
• Depth is Crucial: The hole should be no deeper than the height of the root ball. The top of the root ball should be level with, or slightly above, the surrounding soil grade. Planting too deep is a common mistake that leads to suffocation and root rot.
• Sloping Sides: Create a saucer-like shape with gently sloping sides rather than straight-down walls.
• Soil Mound: If your soil drainage is poor, consider planting on a slight mound to elevate the root crown.

Step 2: Preparing the Plant

Before placing the arborvitae in its new home, a little preparation goes a long way.

• Remove from Container: Carefully remove the plant from its nursery container. You may need to gently tap the sides or bottom, or even lay it on its side and slide it out. Avoid pulling the plant out by its stem.
• Loosen Roots: If the roots are tightly circling the root ball (pot-bound), gently tease them apart with your fingers or a small hand trowel. You can also make a few vertical cuts with a clean knife on the sides of the root ball to encourage outward growth.
• Burlap & Wire Baskets: If your plant comes with burlap or a wire basket, remove as much of it as possible. Burlap should be cut away from the top and sides, especially around the root flare. Wire baskets should be cut and removed entirely if feasible, or at least the top portion to prevent girdling roots later.

Step 3: Positioning and Backfilling

Careful placement and proper backfilling ensure good root-to-soil contact.

• Place the Plant: Center the ‘Emerald Green’ Arborvitae in the hole. Double-check that the top of the root ball is level with or slightly above the surrounding soil. The root flare (where the trunk widens at the base) should be visible.
• Backfill Gently: Begin backfilling the hole with the soil you removed, mixing in any organic amendments like compost if desired. Do not add potting mix or drastically different soil types unless you are amending the entire planting area.
• Firm the Soil: As you backfill, gently firm the soil around the root ball with your hands or feet to remove large air pockets. Avoid compacting the soil too tightly, as roots need oxygen.
• Watering Basin: Create a small, temporary watering basin around the perimeter of the hole to help direct water to the root zone.

Step 4: Initial Watering

This is arguably the most critical step immediately after planting.

• Water Deeply: Immediately after backfilling, water the plant thoroughly and slowly. Allow the water to soak in completely, then water again until the soil is consistently moist but not waterlogged. This settles the soil around the roots.
• Check for Settling: After watering, the soil level may settle. Add more soil if necessary to maintain the correct grade.

Post-Planting Care for Thriving Arborvitae

Your work isn’t over once the plant is in the ground. Consistent aftercare is essential for successful establishment and long-term health.

Watering Schedule

The first year is critical for establishing a strong root system. Consistent moisture is key.

• Frequency: Water regularly, typically 2-3 times per week during dry periods, for the first growing season. Adjust frequency based on weather, soil type, and plant size.
• Depth: Ensure water penetrates deeply into the root zone. A good rule of thumb is to provide 1 inch of water per week, either from rain or irrigation.
• Check Moisture: Always check the soil moisture before watering. Stick your finger 2-3 inches into the soil; if it feels dry, it’s time to water. Avoid surface watering, which encourages shallow roots.
• Seasonal Adjustment: Reduce watering frequency in cooler weather and increase it during hot, dry spells.

Mulching for Success

Mulch is a gardener’s best friend, especially for newly planted trees and shrubs.

• Apply Mulch: Spread a 2-3 inch layer of organic mulch (e.g., shredded bark, pine needles, wood chips) over the entire root zone, extending out to the drip line.
• Benefits: Mulch conserves soil moisture, suppresses weeds, moderates soil temperature, and slowly adds organic matter as it breaks down.
• Avoid “Mulch Volcanoes”: Keep mulch several inches away from the trunk of the arborvitae. Piling mulch against the trunk can trap moisture, leading to rot and pest problems.

Fertilization and Pruning

‘Emerald Green’ Arborvitae are generally not heavy feeders, and excessive fertilization can do more harm than good.

• Initial Fertilization: Avoid fertilizing immediately after planting. Allow the plant to focus its energy on root establishment. Wait until the second growing season.
• When to Fertilize: If a soil test indicates a nutrient deficiency, use a balanced, slow-release fertilizer (e.g., 10-10-10 or 5-10-5 NPK) in early spring. Follow package directions carefully.
• Pruning: ‘Emerald Green’ Arborvitae naturally maintains its dense, pyramidal shape, so heavy pruning is rarely needed.
• Maintenance Pruning: Prune only to remove dead, damaged, or diseased branches. You can also lightly shear the tips in late spring or early summer to maintain a desired size or density, but avoid cutting into old wood, which may not regrow.

Common Challenges and Troubleshooting

Even with the best care, sometimes issues arise. Knowing what to look for can help you address problems quickly.

Pests and Diseases

‘Emerald Green’ Arborvitae are generally robust, but they can occasionally fall victim to certain issues.

• Bagworms: These caterpillars create cone-shaped bags from silk and foliage. Hand-pick them off or use a targeted insecticide if infestations are severe.
• Spider Mites: Tiny pests that cause stippling (tiny yellow dots) on foliage, leading to a dull, bronze appearance. Look for fine webbing. Treat with insecticidal soap or horticultural oil.
• Root Rot: Often a result of poor drainage or overwatering. Symptoms include yellowing, browning, and wilting foliage. Prevention through proper site selection and watering is key.
• Canker: Fungal disease causing sunken, discolored areas on branches. Prune out affected branches promptly with sterilized tools.

Environmental Stress

Environmental factors can also impact your arborvitae’s health.

• Winter Burn: Browning of foliage, especially on the side exposed to winter sun and wind, is common. Ensure adequate watering into late fall. Consider anti-desiccant sprays or burlap screens in exposed locations.
• Drought Stress: Yellowing or browning tips, overall dull appearance. Indicates insufficient watering.
• Nutrient Deficiencies: Overall yellowing (chlorosis) can indicate an iron or magnesium deficiency, especially in alkaline soils. A soil test will confirm.

Safety First: Protecting Yourself and Your Plants

Gardening is enjoyable, but always prioritize safety, especially when handling tools or chemicals.

• Wear Gloves: Protect your hands from blisters, thorns, and soil contaminants.
• Eye Protection: Always wear safety glasses when pruning or using power tools to prevent debris from entering your eyes.
• Proper Footwear: Wear sturdy, closed-toe shoes to protect your feet from shovels, roots, and falling objects.
• Tool Handling: Use sharp, clean tools. Store them properly after use. Be mindful of your surroundings when working with shovels, pruners, or other sharp objects.
• Lifting Techniques: Bend with your knees, not your back, when lifting heavy plants or bags of soil to prevent injury.
• Chemical Safety: If using any fertilizers or pest control products, always read and follow the manufacturer’s instructions carefully. Wear appropriate personal protective equipment (PPE) as specified.
