How close to plant arborvitae for hedge? You should plant arborvitae based on the mature width of the variety you choose, typically spacing them 3 to 4 feet apart for a dense, full hedge.
This spacing allows the branches to fill in nicely without overcrowding, so your hedge looks lush and even from the start.
If you plant arborvitae too close together, they’ll compete for water and nutrients, which can stress the plants and lead to bare patches over time.
On the other hand, planting them too far apart leaves gaps that never close, defeating the purpose of a privacy hedge.
In this post, we’ll break down exactly how close to plant arborvitae for hedge success, covering spacing guidelines, key factors, and practical tips.
Let’s dig in.
How Close to Plant Arborvitae for a Dense Hedge
The ideal spacing when you plant arborvitae for hedge density depends on the mature spread of the specific cultivar you’re using.
For most arborvitae varieties, a spacing of 3 to 4 feet between centers gives you a thick, seamless wall within a few years.
Here are common scenarios to help you determine how close to plant arborvitae for hedge goals.
1. Emerald Green Arborvitae Spacing
Emerald Green arborvitae are one of the most popular choices for hedges because they stay compact and upright.
When you plant arborvitae for hedge with Emerald Green, space them 3 feet apart from center to center.
This distance allows their narrow pyramidal shape to grow together while leaving enough room for airflow.
At 3 feet apart, you’ll get a solid green barrier in about 3 to 4 years.
2. Green Giant Arborvitae Spacing
Green Giant arborvitae grow much larger and faster, so you need more room between each plant.
For these vigorous growers, you should plant arborvitae for hedge spacing around 5 to 6 feet apart.
If you space Green Giants any closer, they’ll quickly become overcrowded and may suffer from disease.
At 5 feet apart, they’ll still knit together into a tall privacy screen within 2 to 3 years thanks to their fast growth rate.
3. Pyramidal and Techny Arborvitae Spacing
Medium-size arborvitae like Pyramidal or Techny types usually reach 10 to 15 feet wide at maturity.
When you plant arborvitae for hedge with these varieties, aim for 4 feet between plants.
This spacing gives you a dense hedge without the risk of lower branches dying off from lack of sunlight.
Four feet apart works well for most mid-sized arborvitae used in formal hedges.
Factors That Affect How Close to Plant Arborvitae for Hedge
Your specific site conditions can change the ideal spacing when you plant arborvitae for hedge success.
Consider these factors before setting your plants in the ground.
1. Soil Quality and Drainage
Rich, well-draining soil supports faster growth, so you can space arborvitae a little farther apart if your soil is excellent.
Poor soil or heavy clay may stunt growth, meaning you need to plant arborvitae for hedge slightly closer to ensure gaps fill in.
Test your soil before planting and amend it if needed to give your hedge the best start.
2. Sunlight Availability
Arborvitae need full sun to grow dense and full from top to bottom.
If your hedge site gets partial shade, the plants may grow slower and stay less dense.
In shadier spots, you might want to plant arborvitae for hedge a little closer, say 2.5 to 3 feet for compact varieties.
More sunlight allows for wider spacing because the foliage will fill in faster and thicker.
3. Desired Hedge Height and Thickness
How tall and thick you want your hedge influences how close to plant arborvitae for hedge purposes.
If you want a tall, solid privacy wall, keep spacing on the tighter side of the recommended range.
For a lower, more ornamental hedge, you can space them a bit wider and allow natural shape to show.
Always check the mature height and width of your chosen variety before finalizing spacing.
Tips for Planting Arborvitae at the Right Distance
Getting the spacing right when you plant arborvitae for hedge is easier with a few practical steps.
Follow these tips to ensure your hedge thrives and looks uniform.
1. Measure from Center to Center
Always measure spacing from the center of one planting hole to the center of the next, not from the edge of the root ball.
This ensures consistent distance between all arborvitae in your hedge line.
Use a measuring tape and stakes to mark each planting spot before you dig.
2. Stagger for a Thicker Look
If you want a super-dense screen, consider planting a double row in a staggered pattern.
When you plant arborvitae for hedge in two rows, space the rows 3 to 4 feet apart and offset the plants in a zigzag.
This technique fills gaps faster and creates a hedge that blocks wind and views more effectively.
3. Water and Mulch After Planting
Proper aftercare helps your arborvitae establish quickly, regardless of how close to plant arborvitae for hedge.
Water deeply after planting and maintain consistent moisture during the first year.
Apply 2 to 3 inches of mulch around the base to retain moisture and suppress weeds, but keep mulch away from the trunk.
So, How Close Should You Plant Arborvitae for a Hedge?
You should plant arborvitae for hedge based on the mature width of the specific variety, with 3 feet being a common sweet spot for compact types.
How close to plant arborvitae for hedge success depends on whether you choose Emerald Green, Green Giant, or another cultivar.
Remember that spacing tighter than recommended leads to competition, while wider spacing leaves gaps.
With the right distance, your arborvitae will grow into a beautiful, dense hedge that provides privacy and curb appeal for years.
