How to Plant Emerald Green Arborvitae: Step-by-Step Guide

Choosing the Right Time of Year for Planting

For the best results, plant your Emerald Green Arborvitae in early spring or early fall. These seasons offer cooler temperatures and moist soil conditions, which help the roots establish without the stress of extreme heat or cold.

Avoid planting in the middle of summer when the scorching sun can dry out the plant, or in late fall when the ground might freeze before roots settle. If you must plant during summer, keep the soil consistently moist and provide some afternoon shade to protect your new shrub.

Timing is everything for a healthy, thriving hedge.

Preparing the Planting Site and Soil

Start by selecting a location with full sun to partial shade, as Arborvitae thrives in bright light. The soil should be well-draining to prevent root rot, so avoid low-lying areas where water collects.

Loosen the soil in a wide area—about twice the width of the root ball—and mix in organic compost to improve drainage and nutrients. This step ensures the roots can spread easily and access the resources they need.

A little prep now goes a long way in promoting vigorous growth for years to come.

Digging the Hole and Positioning the Shrub

Dig a hole that is twice as wide as the root ball but no deeper than the container it came in. This prevents the shrub from settling too deep, which can suffocate the roots. Gently remove the plant from its pot, teasing out any circling roots to encourage outward growth.

Place the Arborvitae in the center of the hole, ensuring the top of the root ball is slightly above ground level. Stand back and check that it’s straight before moving on—this small adjustment ensures a polished, uniform look for your hedge.

Backfilling, Watering, and Mulching

Fill the hole with the soil you removed, tamping it down gently to eliminate air pockets. Water thoroughly to settle the soil and hydrate the roots. Apply a 2-3 inch layer of organic mulch around the base, but keep it a few inches away from the trunk to prevent rot.

Mulch retains moisture and suppresses weeds, giving your Arborvitae a strong start. Water deeply once a week for the first year, adjusting for rainfall, to keep the soil consistently moist but not waterlogged.

Where Is the Best Place to Plant Emerald Green Arborvitae?

Sunlight Requirements: Full Sun vs. Partial Shade

For the best results, plant your Emerald Green Arborvitae in a location that receives full sun to partial shade. These hardy evergreens thrive when they get at least six hours of direct sunlight daily, which helps them maintain their dense, vibrant green foliage.

While they can tolerate some shade, especially in the hotter afternoon hours, too much shade can cause the branches to thin out and look sparse. If you are planting them near a larger structure or tree, ensure they aren’t completely overshadowed.

A spot with morning sun and some afternoon protection is ideal, particularly in hotter climates. This balance keeps the tree healthy and prevents winter burn, ensuring your hedge stays lush year-round. Remember, good light exposure is the secret to that classic emerald color.

Spacing for Hedges vs. Specimen Planting

Determining the right spacing depends on whether you want a tight privacy screen or standalone accents. For a dense hedge, space your Arborvitae about 2 to 3 feet apart from the center of each trunk. This close planting encourages the branches to interlock, creating a solid green wall quickly.

If you prefer them as individual specimens, allow at least 4 to 6 feet of space between plants so they can maintain their natural, pyramidal shape without overcrowding. Proper spacing is crucial because it allows for necessary air circulation, which reduces the risk of fungal diseases.

Don’t be tempted to squeeze them too close together too soon; give them room to grow into their mature width of about 3 to 4 feet for a landscape that looks great for decades.

Soil Drainage and pH Preferences

Emerald Green Arborvitae is adaptable but performs best in well-draining soil that isn’t prone to standing water. They dislike having “wet feet,” so avoid heavy clay areas that stay soggy after rain, as this can lead to root rot.

Instead, aim for a loamy soil that retains moisture without becoming waterlogged. Regarding pH, these trees prefer a slightly acidic to neutral range, roughly between 6.0 and 8.0. If your soil is too alkaline, you might notice the foliage yellowing over time.

Before planting, it is helpful to amend your dirt with organic compost to improve drainage and texture. This simple step gives the young roots a strong start and helps the tree establish itself faster in its new home.

How Deep Should You Plant an Emerald Green Arborvitae?

Identifying the Root Flare

To plant your Emerald Green Arborvitae correctly, you first need to find the root flare—that vital spot where the trunk widens at the base and roots begin to spread out. Gently brush away the top layer of soil from the root ball until you see this natural widening.

It’s common for nursery-grown trees to be buried too deep in their containers, so don’t assume the current soil level is correct. This flare needs to sit slightly above the final soil line in your yard.

Planting too deep suffocates the tree and invites rot, while planting too high exposes roots to drying air. Take your time to locate this marker before digging, ensuring your tree gets the healthy start it deserves.

Avoiding Common Depth-Related Mistakes

A major pitfall new gardeners face is digging a hole like a deep crater for their Emerald Green Arborvitae. Instead, you should aim for a hole that is two to three times wider than the root ball but no deeper than the height of the root ball itself.

This shallow, wide approach encourages roots to grow outward into the nutrient-rich topsoil rather than circling downward. Once placed, ensure the top of the root ball remains visible, rising about an inch above the surrounding grade. Settling is inevitable, so this slight elevation prevents the tree from sinking later.

Remember, it is always safer to plant a bit too high than too deep to protect your investment.

Adjusting for Heavy or Sandy Soils

Your local soil type dictates how you handle the planting depth and backfill. If you have heavy clay soil, which drains poorly, you must plant the tree even higher to prevent water from pooling around the trunk.

In this case, leave the top third of the root ball exposed and mound soil over the sides. Conversely, for sandy soil that drains quickly, you can plant the tree level with the ground, but ensure you water frequently to combat rapid drainage.

Always amend the excavated soil with organic compost to improve texture and moisture retention. By tailoring the depth to your specific soil conditions, you create a stable foundation that keeps your Emerald Green Arborvitae thriving for years to come.

How Often Should You Water Newly Planted Arborvitae?

Watering Schedule for the First Two Weeks

Right after planting your Emerald Green Arborvitae, you want to give the root ball a good, deep soaking. This eliminates air pockets and helps the soil settle around the roots. For the first two weeks, water daily or every other day, depending on the weather.

If it’s hot and sunny, check the soil daily; if it’s cool or rainy, you might skip a day. The goal is to keep the soil moist but not waterlogged. A slow trickle from a hose for 10-15 minutes works best, allowing water to penetrate deeply.

Avoid quick splashes, which only wet the surface. Mulching around the base with 2-3 inches of wood chips helps retain moisture. Just keep the mulch a few inches away from the trunk to prevent rot. Consistent water now sets the stage for strong growth later.

Establishing Roots: Months 1 Through 6

Once your tree passes the two-week mark, you can taper off watering. For the first six months, aim to water every 3-4 days, adjusting for rainfall. Stick your finger about 2 inches into the soil—if it feels dry, it’s time to water. If it’s still damp, wait another day.

Deep, infrequent watering encourages roots to grow downward, making the tree more drought-resistant. During hot summer spells, you may need to increase frequency, while cooler spring or fall days might require less. Always prioritize morning watering to reduce evaporation and give foliage time to dry, preventing disease.

By month six, your Arborvitae should be well-established, but keep an eye on it during extreme heat. A slow-release fertilizer applied in early spring can also support healthy root development during this critical phase.

Signs of Overwatering vs. Underwatering

Knowing the difference between over and underwatering can save your tree. Underwatered Arborvitae often show browning, brittle foliage, especially on the inner branches or tips. The soil will pull away from the pot or feel dusty dry. On the flip side, overwatered trees develop yellowing, drooping leaves that feel mushy.

The soil may smell sour or stay soggy for days. Root rot is a common risk of too much water, leading to wilted or discolored branches despite wet soil.

If you spot these signs, adjust your routine—let the soil dry out slightly if overwatered, or increase water if it’s too dry. Remember, it’s easier to fix underwatering than root rot, so when in doubt, err on the side of slightly drier soil.

Do Emerald Green Arborvitae Need Fertilizer When Planting?

Using Root Stimulators vs. Heavy Fertilizers

When planting your Emerald Green Arborvitae, it’s best to skip heavy chemical fertilizers and instead opt for a gentle root stimulator. Heavy fertilizers can actually burn the tender new roots and cause more harm than good during the critical establishment phase.

Root stimulators are specifically designed to encourage strong root development without the risk of overwhelming the plant. These products typically contain lower concentrations of nutrients like phosphorus, which is essential for root growth, along with helpful vitamins and hormones.

Using a root stimulator gives your tree the gentle kickstart it needs to settle into its new home. Remember, the goal right now is root development rather than rapid top growth.

By focusing on the roots first, you ensure the tree is stable and ready to absorb nutrients effectively later on. Mix the stimulator with water as directed on the label and apply it directly to the root zone immediately after planting to reduce transplant shock and encourage success.

Timing Your First Fertilizer Application

Patience is key when it comes to fertilizing your newly planted Arborvitae. You should wait until the tree has had time to establish itself before applying any standard fertilizer.

A good rule of thumb is to wait until the following spring after planting, giving the roots several months to settle into the surrounding soil. Fertilizing too early can force tender new growth that may not survive winter or harsh weather conditions.

Instead, focus on consistent watering during the first growing season, as this is the most critical factor for survival. Once the tree has been in the ground for a year, you can begin a regular fertilization schedule to promote lush, green foliage.

Look for signs of new growth in the spring; this indicates the roots are functioning well. Applying a slow-release fertilizer at this time will support the tree’s energy needs without causing a sudden surge of vulnerable growth that could damage the plant’s long-term health.

Best Fertilizer Types for Acid-Loving Conifers

Emerald Green Arborvitae thrive in slightly acidic soil, so choosing the right fertilizer makes a big difference in their health and color. For established trees, a granular fertilizer formulated specifically for evergreens or acid-loving plants is an excellent choice.

Products labeled for shrubs like holly or rhododendrons often work wonderfully because they provide the right balance of nutrients. Look for a fertilizer with a higher nitrogen content to support that vibrant green foliage, such as an NPK ratio like 10-8-6.

Alternatively, you can use acidifying fertilizers to help maintain the lower soil pH these conifers prefer. Always follow the application instructions carefully to avoid over-fertilizing, which can lead to burnt roots or yellowing leaves. Applying mulch around the base of the tree also helps maintain soil acidity and moisture levels.

By selecting the correct product, you ensure your arborvitae has the specific nutrients required to remain dense, hardy, and beautiful throughout the changing seasons.

How to Care for Emerald Green Arborvitae After Planting

Pruning Tips for Shaping and Density

To keep your Emerald Green Arborvitae looking its best, light pruning once a year is usually enough. Focus on trimming the outer growth to encourage denser foliage and maintain a neat shape. Avoid cutting into old, woody branches, as this can leave bare spots that won’t regrow.

The best time to prune is in late winter or early spring, just before new growth starts. Use sharp, clean shears to make precise cuts, and aim for a slightly narrower top to allow sunlight to reach lower branches.

If you notice any dead or damaged limbs, remove them promptly to prevent disease spread. Regular, gentle trimming will help your trees stay full and vibrant without over-stressing them.

Protecting Young Plants from Winter Burn

Young Arborvitae are susceptible to winter burn, especially in harsh climates. To prevent this, water your trees deeply in the fall to ensure they’re hydrated before the ground freezes. Apply a 2-3 inch layer of organic mulch around the base to retain moisture and insulate roots.

Consider wrapping the trees in burlap or using anti-desiccant sprays to shield them from drying winds and intense sun. Position them away from salty roads or driveways, as salt spray can damage foliage.

If winter burn occurs, don’t panic—lightly prune affected areas in spring, and the tree should recover with proper care.

Managing Pests and Common Diseases

Emerald Green Arborvitae are generally hardy, but they can face issues like bagworms, spider mites, or fungal diseases. Inspect your trees regularly for signs of trouble, such as discolored needles or webbing. For pests like bagworms, handpick them off or use an insecticidal soap if the infestation is severe.

To prevent fungal problems, ensure good air circulation by spacing trees properly and avoiding overhead watering. If you spot spider mites, a strong blast of water from a hose can often dislodge them. Early detection and prompt action are key to keeping your trees healthy and pest-free.

Troubleshooting Common Planting Problems

Why Is My Arborvitae Turning Brown After Planting?

If your newly planted arborvitae starts turning brown, don’t panic—it’s often a sign of transplant shock or water stress. These trees have shallow root systems that dry out quickly, especially right after planting.

Check the soil moisture by sticking your finger about two inches deep; if it feels dry, give the tree a slow, deep watering immediately. On the flip side, browning can also happen if the roots are sitting in waterlogged soil, causing them to rot.

Ensure you planted it at the right depth—too deep suffocates the roots, while too shallow exposes them. Mulching around the base helps retain moisture, but keep it a few inches away from the trunk to prevent fungal issues. With proper care, the browning should fade as new growth emerges.

Fixing Poor Drainage or Root Rot Issues

Emerald Green Arborvitaes hate wet feet, so poor drainage can quickly lead to root rot, a serious fungal issue. If your tree’s foliage is yellowing or wilting despite watering, dig a small test hole near the roots. If it’s soggy or smells foul, your soil isn’t draining well.

To fix this, you may need to relocate the tree to a raised bed or amend the soil with organic matter like compost to improve drainage. Avoid planting in heavy clay soils unless you mound the soil above ground level.

If root rot has already set in, trim away any black, mushy roots and treat the remaining healthy roots with a fungicide. Moving forward, water less frequently but deeply, allowing the soil to dry slightly between sessions to keep the roots healthy and happy.

Reviving a Transplant Shocked Shrub

Transplant shock is common when moving arborvitaes, but you can help them bounce back with a little TLC. First, prune back about one-third of the foliage to reduce the plant’s energy demand while its roots re-establish.

Apply a root stimulator or diluted liquid fertilizer to encourage strong root growth without overwhelming the tree. Keep the soil consistently moist but not waterlogged—this balance is crucial during recovery.

Shield the shrub from harsh afternoon sun or strong winds for a few weeks using burlap or a temporary shade cloth, as these stressors can worsen shock. Be patient; recovery can take a few months. Once you see fresh green growth, you’ll know your arborvitae is settling in nicely.
