You should plant arborvitae between 3 and 6 feet apart for privacy.
The exact distance depends on the variety you choose and how quickly you want that solid screen.
Planting arborvitae for privacy is popular, but wrong spacing causes gaps or overcrowding.
In this post, we’ll cover exactly how far apart to plant arborvitae for privacy.
How Far Apart Should You Plant Arborvitae For Privacy
Let’s dive into the specific recommendations for how far apart to plant arborvitae for privacy.
The Standard Spacing Range
For most varieties, space them 3 to 4 feet apart for a tight hedge.
Larger species like Green Giant need 5 to 6 feet apart.
Consider mature width and plant at half that distance from center to center.
For a 6-foot-wide arborvitae, that means 3 feet apart for a continuous screen.
Always check the plant tag for specific recommendations.
Why Spacing Matters for Privacy
The goal is for branches to touch as they grow.
If you plant arborvitae for privacy too far apart, you’ll see gaps.
Too close causes root competition and stressed plants that may thin out.
Good spacing also ensures air circulation, which reduces disease risk.
A uniform hedge also improves your property’s curb appeal.
How to Measure the Spacing
Check the mature width on the plant tag.
Divide by two to get the optimal spacing from center to center.
For example, an 8-foot-wide arborvitae should be 4 feet apart.
Plant at least 2 feet from fences or walls to allow for growth.
Use stakes to mark your planting spots for consistency.
Measure from the center of each planting hole for accuracy.
Factors That Affect How Far Apart You Plant Arborvitae For Privacy
Several factors influence your spacing decision when planting arborvitae for privacy.
Arborvitae Variety
Growth habits vary significantly between varieties.
Emerald Green grows narrow and upright, so 3 feet apart works well.
Green Giant spreads wide and fast, so 5 to 6 feet apart is better.
Techny arborvitae are medium-sized and do well at 4 feet apart.
Some dwarf varieties can be planted even closer, like 2 feet apart.
Always check the mature width of your chosen cultivar.
Desired Height and Density
If you want a tall privacy screen, you may need wider spacing to prevent crowding at the top.
For a shorter hedge, closer spacing creates density faster.
A 6-foot hedge requires different spacing than a 15-foot one.
Consider how much height you need to block unwanted views.
Climate and Soil Conditions
Rich soil and consistent moisture lead to faster growth and wider spread.
In these conditions, you can plant arborvitae for privacy slightly further apart.
Poor soil or dry climates slow growth, so closer spacing ensures a denser screen sooner.
Full sun encourages dense foliage, while partial shade may result in looser growth.
Water deeply after planting to help roots establish.
Spacing Tips for Different Arborvitae Varieties
Here’s how far apart to plant arborvitae for privacy by specific variety.
Emerald Green Arborvitae
Plant Emerald Green 3 feet apart for a tight, elegant hedge.
They mature at 3 to 4 feet wide and up to 15 feet tall.
This spacing creates a solid screen without overcrowding.
They are low-maintenance and hold their color all year.
They are deer-resistant in many areas.
Green Giant Arborvitae
Plant Green Giant 5 to 6 feet apart.
They can reach 50 feet tall and spread 12 to 15 feet wide.
Wider spacing allows them to develop their natural shape.
They are one of the fastest-growing options for privacy.
They are often used as windbreaks.
Techny Arborvitae
Space Techny arborvitae 4 feet apart.
They grow to about 15 feet tall and 5 feet wide.
They are very cold-hardy and resistant to deer browsing.
Their dense shape provides excellent year-round coverage.
They keep their color in winter.
Pyramidal Arborvitae
Plant Pyramidal arborvitae 3 to 4 feet apart.
They grow narrow, reaching 20 feet tall with a 4 to 5 foot spread.
This variety is great for smaller yards needing vertical privacy.
They tolerate pruning better than other arborvitae.
Common Mistakes When Planting Arborvitae for Privacy
Avoid these errors to ensure your planting arborvitae for privacy project succeeds.
Planting too close
Many think closer is better, but planting arborvitae for privacy too close stunts growth.
Roots compete and inner branches die, leaving gaps.
Thinning may be required later if planted too close.
Follow recommended spacing for your variety.
Ignoring mature size
Don’t plant based on the size they are today.
Consider their full grown width to avoid overcrowding.
This mistake is common with novice gardeners.
Poor soil preparation
Arborvitae need well-drained soil.
Amend heavy clay or sandy soil before planting.
Add organic matter to improve soil structure.
Proper drainage is critical to prevent root rot.
So, How Far Apart Should You Plant Arborvitae For Privacy
You should plant arborvitae for privacy between 3 and 6 feet apart depending on the variety and your goals.
For a dense, quick screen, closer spacing like 3 feet for Emerald Green works well.
For larger varieties like Green Giant, 5 to 6 feet apart allows them to thrive.
Always check the mature width and consider climate and soil conditions.
With careful planning, your arborvitae screen will provide beautiful, lasting privacy.
