How fast does an arborvitae grow is one of the most common questions for homeowners planning a privacy hedge.
The answer is that the growth rate of an arborvitae varies wildly depending on the specific variety you plant, the soil quality, and the sunlight.
Some arborvitae trees grow incredibly fast, adding several feet each year, while others grow at a much more moderate pace of just a few inches.
Understanding how fast do arborvitae grow is crucial for planning your landscape design, whether you need a quick screen or a low border.
In this post, we will explore typical growth rates for different types of arborvitae, what affects these rates, and how you can help your arborvitae grow to its fullest potential.
Understanding How Fast An Arborvitae Grows
To truly answer how fast does an arborvitae grow, you must look at its genetics and environment.
It Depends on the Specific Variety
The growth rate of an arborvitae is primarily determined by its specific cultivar.
Some varieties, like the Green Giant, have a very fast arborvitae growth rate.
Others, like the Emerald Green, are naturally slower and stay more compact.
So if you are asking how fast does an arborvitae grow, identify the exact type you have first.
The Importance of Proper Conditions
Even a fast-growing variety won’t reach its potential in poor soil or improper sunlight.
To get the best arborvitae growth rate, provide rich, well-draining soil and plenty of sun.
Arborvitae trees grow best with at least six hours of direct sun each day.
If planted in deep shade, your arborvitae grow much slower than expected.
How Fast Do Arborvitae Grow in the First Year?
Many people ask how fast do arborvitae grow right after planting.
In the first year, arborvitae trees grow mostly underground as their root systems establish.
You might see only minimal top growth while they focus on rooting into the soil.
Once established, the visible annual growth often kicks in significantly during the second and third years.
Patience in the beginning leads to a stronger, faster-growing plant overall.
How Climate Impacts Growth Rate
Your USDA hardiness zone plays a role in how fast does an arborvitae grow.
Arborvitae thrive in zones 3 through 8 for most common varieties.
Extreme heat or drought can slow the annual growth significantly.
Providing adequate water during dry spells is key to maintaining a steady arborvitae growth rate.
How Fast Do Common Arborvitae Varieties Grow?
Let’s look at specific numbers for popular arborvitae cultivars.
Green Giant Arborvitae Growth Rate
The Green Giant is famous for its incredible speed.
How fast does an arborvitae grow if it is a Green Giant?
Once established, it can reach three to five feet per year in height.
This makes it one of the fastest-growing evergreens for a dense visual barrier.
Emerald Green Arborvitae Growth Rate
The Emerald Green grows more slowly and is ideal for formal hedges.
How fast does an arborvitae grow if it is an Emerald Green?
You can expect about one to two feet of height increase per year.
This moderate arborvitae growth rate is perfect for a low-maintenance, naturally dense shape.
Other Common Varieties
How fast does an arborvitae grow if you choose Nigra or Woodwardii?
The Nigra arborvitae trees grow about one to two feet per year and hold a deep green color well in winter.
The Woodwardii is a globose shrub form that grows very slowly, adding only a few inches annually.
This makes it perfect for foundation plantings where a compact size is desired.
Height vs. Width Growth
When considering how fast arborvitae grow, remember they grow mostly upward.
Most arborvitae trees grow narrow, maintaining a pyramidal or columnar shape.
Their width increases very slowly, usually only a few inches per year.
Understanding this helps you decide on the right spacing for your hedges.
Tips To Maximize Your Arborvitae Growth Rate
You can influence how fast does an arborvitae grow by optimizing its care.
Soil, Sun, and Water
Arborvitae prefer slightly acidic, well-drained soil amended with compost.
Good soil preparation dramatically improves how fast does an arborvitae grow in your yard.
Consistent watering, especially in the first few years, is vital for a good arborvitae growth rate.
Deep watering encourages deep roots, which supports faster top growth later on.
Fertilizing and Pruning
To maximize growth, use a slow-release evergreen fertilizer in early spring.
While arborvitae trees grow naturally without much pruning, light trimming in spring encourages denser foliage.
To avoid harming your tree, never prune into old wood as it may not regrow.
A little care goes a long way in helping your arborvitae grow its absolute fastest.
Protecting Against Pests and Winter Damage
Pests like bagworms and spider mites can slow down how fast does an arborvitae grow.
Inspect your trees regularly and treat infestations early to keep the growth rate strong.
Wrapping young trees in burlap can prevent winter burn, ensuring they bounce back quickly in spring.
A healthy arborvitae is a fast-growing arborvitae.
So, How Fast Does An Arborvitae Grow?
How fast an arborvitae grows ranges from three to five feet per year for the fastest varieties like Green Giant to just a few inches per year for dwarf types.
Ultimately, how fast does an arborvitae grow in your landscape depends on the variety you choose and the consistent care it receives.
We hope this helps you understand your arborvitae growth rate so you can enjoy their beauty and privacy for years to come.
