Introduction
Emerald Green Arborvitae is one of the most popular evergreen trees for privacy, borders, and year-round landscape structure. Its narrow, upright shape makes it useful for property lines, foundation plantings, driveway borders, and smaller yards where you want greenery without taking up too much space.
This care guide focuses on how to grow Emerald Green Arborvitae successfully, including sunlight, watering, soil, spacing, pruning, winter care, common problems, and privacy screen tips.
What Is Emerald Green Arborvitae?
Emerald Green Arborvitae is a compact, columnar evergreen tree known for its dense green foliage and naturally tidy shape. It is often used as a privacy screen, hedge, windbreak, or vertical accent in residential landscapes.
Unlike larger privacy trees, Emerald Green Arborvitae stays relatively narrow. This makes it a strong choice for homeowners who want evergreen coverage without planting something that becomes too wide or overwhelming over time.

Why Choose Emerald Green Arborvitae?
Emerald Green Arborvitae is popular because it gives homeowners a clean evergreen look without demanding constant care. Its naturally narrow shape makes it easier to place than wider-growing evergreens, especially in suburban yards, along fences, or near outdoor living spaces.
Emerald Green Arborvitae is a good choice if you want:
- A narrow evergreen privacy tree
- Year-round green foliage
- A formal hedge or border
- A low-maintenance foundation planting
- Screening along a fence or property line
- Evergreen structure for smaller yards
It is especially useful where you want a classic privacy screen but do not have room for a very wide tree.
How Much Sun Does Emerald Green Arborvitae Need?
Emerald Green Arborvitae grows best in full sun to partial sun. For the densest foliage and strongest growth, choose a location that receives at least several hours of direct sunlight per day.
It can tolerate some partial shade, but too much shade may cause the tree to grow thinner or less evenly. If you are planting Emerald Green Arborvitae for privacy, a sunnier location will usually help the trees fill in more consistently.
Best light conditions:
- Full sun for the densest growth
- Partial sun in warmer or protected locations
- Avoid deep shade when planting for privacy
- Choose open locations with good airflow when possible
Best Soil for Emerald Green Arborvitae
Emerald Green Arborvitae grows best in well-draining soil. It can adapt to a range of soil types, but it does not like sitting in constantly wet ground.
The most important soil factor is drainage. If water collects around the roots after rain, the tree may become stressed. Poor drainage can lead to browning, thinning, root problems, or slow establishment.
Good soil conditions include:
- Well-draining native soil
- Loamy soil with moderate moisture
- Planting areas that do not stay soggy
- Mulched beds that help regulate soil moisture
If your soil is heavy or compacted, loosen the surrounding area before planting and avoid placing the tree too deep. The root flare should sit near the soil surface, not buried below grade.
How to Plant Emerald Green Arborvitae
Proper planting is one of the most important steps for long-term success. Emerald Green Arborvitae often struggles when it is planted too deeply, watered inconsistently after planting, or placed in soil that stays too wet.
Planting steps:
- Choose a location with full sun to partial sun.
- Dig a hole about twice as wide as the root ball.
- Keep the hole about the same depth as the root ball.
- Place the tree so the root flare is at or slightly above soil level.
- Backfill with native soil and gently firm around the roots.
- Water deeply after planting.
- Add mulch around the base, keeping it away from the trunk.

How to Water Emerald Green Arborvitae
Watering is especially important during the first year after planting. Newly planted Emerald Green Arborvitae trees need consistent moisture while they establish new roots, but they should not sit in soggy soil.
After planting
Water deeply right after planting to help settle the soil around the root ball. During the first few weeks, check the soil regularly and water when the top few inches begin to dry.
During the first growing season
During the first growing season, water deeply and consistently. The exact schedule depends on rainfall, heat, soil type, and how quickly the planting area dries. Hot, dry weather usually requires more frequent watering.
Once established
Once established, Emerald Green Arborvitae becomes lower maintenance, but it may still need supplemental water during drought, extreme heat, or long dry spells.
Watering tips:
- Water deeply instead of lightly sprinkling.
- Check the soil before watering.
- Keep soil evenly moist during establishment.
- Avoid constantly soggy soil.
- Water during dry winter periods if the ground is not frozen.
- Pay extra attention to trees planted near fences, walls, or foundations.

How Far Apart Should You Plant Emerald Green Arborvitae?
Spacing depends on your landscape goal. For a privacy screen, plant Emerald Green Arborvitae closer together so the trees eventually form a continuous wall of green. For individual accents, leave more space between trees so each one can keep its natural shape.
| Landscape Goal | Suggested Approach |
|---|---|
| Privacy screen | Use closer spacing so trees fill in over time. |
| Formal hedge | Plant in a straight line with even spacing. |
| Foundation planting | Leave room between the tree and the home for airflow and mature growth. |
| Specimen tree | Use wider spacing so the tree’s natural shape stands out. |
| Mixed evergreen border | Space based on nearby plants and the desired layered effect. |
Avoid planting too close to walls, fences, driveways, or other trees. Even narrow evergreens need room for healthy root growth, airflow, and long-term maintenance.
Using Emerald Green Arborvitae for Privacy
Emerald Green Arborvitae is one of the most common choices for evergreen privacy screens because it stays green year-round and grows in a naturally narrow form. It works well along property lines, patios, pool areas, fences, and outdoor seating spaces.
Because it is not as wide as many other privacy trees, Emerald Green Arborvitae is especially useful in yards where space is limited. It gives height and coverage without creating an overly bulky screen.
Best privacy uses:
- Property line screens
- Fence line plantings
- Patio privacy
- Poolside screening
- Driveway borders
- Foundation structure
- Formal evergreen rows

How Fast Does Emerald Green Arborvitae Grow?
Emerald Green Arborvitae has a moderate growth rate. It is not usually as fast as larger privacy trees, but it makes up for that with a compact, tidy shape and dependable evergreen structure.
Growth rate depends on sunlight, soil quality, watering, climate, and how well the tree establishes after planting. Trees planted in full sun with consistent moisture usually grow better than trees planted in shade or dry soil.
For a deeper breakdown of yearly growth and mature size, read the Emerald Green Arborvitae Growth Rate Guide.
How Big Does Emerald Green Arborvitae Get?
Emerald Green Arborvitae is valued for its narrow, upright size. It provides height without spreading too widely, which makes it easier to use near homes, fences, and smaller yard spaces.
Actual mature size depends on climate, growing conditions, pruning, and available space. When planning your landscape, leave enough room for the tree to reach its natural width instead of planting it too close to structures or other plants.
How to Prune Emerald Green Arborvitae
Emerald Green Arborvitae naturally grows in a tidy pyramidal shape, so heavy pruning is usually not needed. In most cases, light pruning is enough to maintain its form.
Prune to remove dead, damaged, or uneven growth. You can lightly trim the outer foliage to shape the tree, but avoid cutting deeply into bare interior branches. Arborvitae may not regrow well from old wood that has no green growth.
Pruning tips:
- Prune lightly to maintain shape.
- Remove dead or damaged branches when noticed.
- Avoid cutting into bare old wood.
- Do not remove the main central leader unless necessary.
- Use clean, sharp pruning tools.
- Avoid aggressive shearing unless maintaining a formal hedge.
Fertilizing Emerald Green Arborvitae
Emerald Green Arborvitae usually does not need heavy fertilizing when planted in decent soil. If growth is weak or the soil is poor, a slow-release evergreen or balanced fertilizer can be applied in spring according to the label directions.
Avoid overfertilizing. Too much fertilizer can push soft growth that may be more vulnerable to stress. Healthy root establishment, proper watering, and good sunlight are usually more important than frequent feeding.
Fertilizing tips:
- Fertilize in spring if needed.
- Use a slow-release evergreen or balanced fertilizer.
- Follow label directions carefully.
- Do not fertilize a severely stressed or drought-damaged tree.
- Avoid heavy late-season fertilizing.
For general feeding advice, read the Simply Trees Guide to Fertilizing.
Mulching Around Emerald Green Arborvitae
Mulch helps Emerald Green Arborvitae by conserving soil moisture, reducing weeds, and protecting roots from temperature swings. This is especially helpful during establishment.
Apply a 2 to 3 inch layer of mulch around the base of the tree. Keep mulch several inches away from the trunk. Do not pile mulch against the trunk, because trapped moisture can contribute to bark and root problems.
Emerald Green Arborvitae Winter Care
Emerald Green Arborvitae is an evergreen, so it continues to lose moisture through its foliage during winter. Cold wind, frozen soil, dry conditions, and winter sun can all contribute to browning or winter burn.
The best winter care starts before winter. Keep the tree watered during fall, especially if rainfall has been low. A well-hydrated tree is better prepared for cold weather than a tree that enters winter dry and stressed.
Winter care tips:
- Water well in fall before the ground freezes.
- Add mulch to help regulate soil temperature.
- Protect newly planted trees from harsh wind if needed.
- Avoid heavy late-season pruning.
- Brush off heavy snow gently instead of pulling branches.
- Do not use harsh de-icing salts near the root zone.
Common Emerald Green Arborvitae Problems
Emerald Green Arborvitae is generally low maintenance, but problems can appear when the tree is stressed by poor planting, inconsistent watering, heavy shade, winter exposure, or drainage issues.
1. Browning foliage
Browning can be caused by underwatering, overwatering, transplant shock, winter burn, pest issues, or natural interior shedding. Check soil moisture first before making major changes.
2. Yellowing foliage
Yellowing may happen from watering stress, poor drainage, nutrient issues, or seasonal adjustment. If the soil is constantly wet, improve drainage and reduce watering frequency.
3. Thin growth
Thin or open growth is often caused by too much shade. Emerald Green Arborvitae grows thickest with strong sunlight.
4. Branch bending from snow
Heavy snow can bend upright branches. Gently brush off snow when possible, but avoid forcing frozen branches back into place.
5. Root stress
Root stress is often linked to planting too deeply, soggy soil, drought, or compacted soil. Make sure the root flare is not buried and that water drains properly.
6. Pest pressure
Stressed arborvitae may be more vulnerable to pests. Inspect foliage and branches if you notice thinning, webbing, discoloration, or unusual dieback.
Why Is My Emerald Green Arborvitae Turning Brown?
Browning is one of the most common concerns with Emerald Green Arborvitae. The cause is not always the same, so it is important to look at the pattern.
| Browning Pattern | Possible Cause | What to Check |
|---|---|---|
| Brown tips or outer foliage | Winter burn, drought, wind exposure, or heat stress | Recent weather, watering routine, wind exposure |
| Interior browning | Natural seasonal shedding or low interior light | Whether outer foliage remains healthy and green |
| Lower branches browning | Poor airflow, shade, animal damage, or moisture issues | Drainage, mulch placement, pests, site conditions |
| One side turning brown | Sunscald, wind exposure, road salt, or uneven watering | Exposure, salt use, nearby pavement, irrigation coverage |
| Whole tree declining | Root stress, severe drought, overwatering, or planting issue | Root flare depth, soil moisture, drainage, planting history |
Do not assume every brown branch means the tree is dying. Start by checking soil moisture, drainage, planting depth, and whether the browning is isolated or spreading.

Emerald Green Arborvitae Care Mistakes to Avoid
Planting Too Deeply
Planting too deeply can stress the roots and trunk. Keep the root flare near soil level and avoid burying the base of the tree.
Watering Too Lightly
Shallow watering encourages shallow roots. Water deeply so moisture reaches the root ball and surrounding soil.
Letting New Trees Dry Out
Newly planted arborvitae need consistent moisture while establishing. Dry soil during the first growing season can lead to browning and stress.
Planting in Poor Drainage
Emerald Green Arborvitae does not like constantly wet soil. Avoid low spots where water collects after rain.
Pruning Too Hard
Do not cut deeply into bare old wood. Arborvitae may not fill back in from hard cuts into leafless interior branches.
Planting Too Close Together
Close spacing can help create privacy, but trees still need enough room for airflow, roots, and healthy long-term growth.
