How Close To Plant Emerald Green Arborvitae – For A Perfect Privacy
For a dense, healthy privacy hedge, plant Emerald Green arborvitae 2 to 3 feet apart, measuring from the center of one trunk to the center of the next.
If you want a solid “living wall” effect, lean toward the 2-foot spacing; for a more relaxed, airy look, 3 feet is ideal.
You have decided to transform your backyard into a private sanctuary, and you have chosen the elegant Thuja occidentalis ‘Smaragd’—better known as the Emerald Green arborvitae—to get the job done.
It is a fantastic choice, but many homeowners struggle with the initial layout, wondering exactly how close to plant emerald green arborvitae to ensure they grow together without competing for vital resources.
Get this spacing wrong, and you might end up with gaps that never fill in or, worse, crowded trees prone to fungal disease.
This guide will walk you through the precise measurements and professional techniques needed to establish a lush, thriving landscape feature that lasts for decades.
Understanding how close to plant emerald green arborvitae for success
The secret to a uniform, symmetrical hedge lies in the math you do before you ever pick up a shovel.
When you look at a young, slender nursery plant, it is easy to forget that these trees will eventually reach a width of 3 to 4 feet at maturity.
If you plant them too close, their inner needles will die off due to a lack of sunlight and poor air circulation, leaving you with brown, unsightly patches.
If you plant them too far apart, you will wait years for the branches to touch, defeating the purpose of an immediate privacy screen.
Aim for that sweet spot of 2.5 feet on center if you want a balance between quick closure and long-term health.
Preparing your planting site
Before digging, assess your soil quality and drainage, as these arborvitae are sensitive to “wet feet.”
Clear a strip of turfgrass about 3 feet wide along your intended line to reduce competition for nutrients and water.
Use a rototiller or a garden fork to loosen the soil to a depth of at least 8 to 10 inches, incorporating organic matter like compost to boost soil structure.
If your soil is heavy clay, consider adding coarse sand or fine mulch to help with aeration, which prevents root rot.
Marking your layout
Use a long garden hose or a taut string line to mark the exact path where your hedge will sit.
Take a measuring tape and mark your planting spots with small flags or spray paint, ensuring they are exactly the distance apart you chose.
Consistent spacing is the hallmark of a professional landscape design, so take your time during this step.
Safe and effective planting techniques
Safety is paramount when digging large holes, so always call your local utility company to mark underground lines before you break ground.
Dig your holes twice as wide as the root ball but no deeper than the container they came in.
Planting too deep is a common mistake that can lead to stem rot; the top of the root ball should sit just slightly above the surrounding soil level.
- Gently tease the outer roots if they are circling the pot to encourage outward growth.
- Backfill with a mix of native soil and a small amount of compost.
- Firm the soil gently with your hands to remove large air pockets, then water thoroughly.
Maintenance for long-term health
Even if you know how close to plant emerald green arborvitae, your work is not done once the trees are in the ground.
Young trees require consistent moisture for the first two years, especially during hot, dry summer months.
Apply a 2-inch layer of organic mulch around the base to retain moisture and suppress weeds, but keep it a few inches away from the trunk to prevent decay.
Avoid using heavy nitrogen fertilizers in late summer, as this encourages soft, new growth that can be damaged by the first autumn frost.
Monitoring for common issues
Keep an eye out for pests like bagworms, which can strip foliage quickly if left unchecked.
If you notice browning needles, check for spider mites by shaking a branch over a white piece of paper to see if tiny specks move.
If the trees are properly spaced, air circulation will naturally help reduce the risk of fungal pathogens like Phytophthora root rot.
FAQ: Common concerns for your hedge
How tall will these trees get?
Emerald Green arborvitae typically reach 12 to 15 feet in height, making them perfect for residential privacy screens.
Do I need to prune them?
These trees have a naturally tight, pyramidal shape and rarely require formal pruning.
If you must trim them, do so in early spring, and never cut back into the “dead zone” of older, brown wood, as it will not regrow.
Can I plant them near a fence?
Yes, but ensure there is enough space for the tree to reach its full width without being crushed against the fence material.
Leaving 2 feet of space between the fence and the trunk allows for better airflow and easier maintenance.
Conclusion
Establishing a privacy hedge is a rewarding project that adds both beauty and value to your home.
By understanding how close to plant emerald green arborvitae, you set the stage for a lush, uniform screen that thrives for years to come.
Remember to prioritize soil health, consistent moisture, and careful site preparation during the planting phase.
With the right spacing and a little bit of patience, you will soon enjoy the quiet, green sanctuary you have worked so hard to create.
