Yes, you can plant arborvitae in the fall.
In fact, fall is one of the best times to add these evergreens to your landscape.
If you are asking yourself, “can you plant arborvitae in the fall?” the answer is a solid yes, as long as you time it right.
Planting arborvitae in the fall gives the roots a chance to establish before winter sets in.
Arborvitae planted in the fall tend to experience less transplant shock than those put in during the heat of summer.
The cooler soil and air temperatures reduce stress on the tree, making it easier for your arborvitae to settle in.
In this post, we will explore why you can plant arborvitae in the fall, how to do it successfully, and what varieties work best.
Let’s dig in so you can grow a healthy, beautiful arborvitae hedge or screen.
Why You Can Plant Arborvitae in the Fall
If you plant arborvitae in the fall, the conditions are ideal for root growth.
Here are the main reasons fall planting works so well for arborvitae.
Cooler Temperatures Reduce Transplant Stress
When you plant arborvitae in the fall, the cooler temperatures help the tree focus on root development instead of fighting heat.
Arborvitae planted in the fall don’t have to deal with the wilting stress that summer heat causes.
This means your arborvitae can settle into the soil with less water loss through the leaves.
The result is a healthier start for any arborvitae you put in the ground during autumn.
Soil Is Still Warm Enough for Root Growth
Even though the air is cool, the soil stays warm well into the fall.
When you plant arborvitae in the fall, the soil temperature encourages roots to spread before the ground freezes.
This warm soil is the perfect environment for the fine feeder roots of arborvitae to explore the surrounding dirt.
Because arborvitae are shallow-rooted, they benefit greatly from that extra growth window.
Less Competition from Weeds and Pests
Fall means fewer weeds and fewer active pests.
If you plant arborvitae in the fall, you won’t have to fight as hard to keep the area clean.
Many common arborvitae pests, like bagworms, are less active in cooler weather.
This gives your young arborvitae a better chance to grow without being chewed or outcompeted.
Roots Establish Before Winter Dormancy
Arborvitae planted in the fall have a head start on root establishment.
Those roots continue to grow as long as the soil temperature stays above about 40°F.
By the time spring arrives, your arborvitae will already have a strong root system ready to support new top growth.
That’s why so many gardeners say, “Yes, you can plant arborvitae in the fall and get great results.”
Best Practices for Planting Arborvitae in the Fall
To make sure your arborvitae survive and thrive, follow these tips.
Time Your Planting Correctly
The best window to plant arborvitae in the fall is about 6 to 8 weeks before the first hard frost.
This gives the roots enough time to adjust.
Check your local frost dates and aim to get your arborvitae in the ground by mid-October in most northern zones.
In warmer areas, you can plant arborvitae in the fall even later, all the way through November.
Water Deeply After Planting
Even though it’s cooler, your arborvitae still need consistent moisture.
When you plant arborvitae in the fall, give them a deep soak right after putting them in the ground.
Then water weekly until the ground freezes if rain is scarce.
Don’t let the root ball dry out, but don’t drown it either.
A good rule is to check the soil one inch down, and if it’s dry, it’s time to water.
Mulch to Protect Roots
Mulch is a lifesaver for arborvitae planted in the fall.
Apply a 2 to 4 inch layer of organic mulch around the base, keeping it away from the trunk.
This helps insulate the soil, keeping it warm longer so roots can keep growing.
It also prevents frost heaving, where the freeze-thaw cycle pushes young arborvitae out of the ground.
Straw, wood chips, or shredded bark all work well.
Don’t Fertilize in Fall
You might be tempted to feed your arborvitae, but hold off.
When you plant arborvitae in the fall, adding fertilizer can stimulate tender new growth that will get killed by frost.
Wait until early spring to fertilize your arborvitae.
That way the tree uses its energy for root growth now, not leaves.
Types of Arborvitae That Thrive When Planted in the Fall
Not all arborvitae are created equal, but most handle fall planting well.
Here are two popular choices that are especially reliable.
Emerald Green Arborvitae
This is the classic narrow arborvitae for privacy screens.
If you plant arborvitae in the fall, Emerald Green is a top choice because it’s hardy in zones 3 to 8.
It grows slowly but steadily, so the fall planting window gives it plenty of time to establish without rushing.
Its dense foliage stays rich green all winter, adding beauty even in the cold months.
Green Giant Arborvitae
For a fast-growing hedge, Green Giant is unbeatable.
You can plant arborvitae in the fall with this variety and see it take off the following spring.
It grows up to 3 feet per year, so the fall head start really pays off.
Green Giant is also very adaptable to different soil types, making it a forgiving choice for fall planting.
Common Mistakes to Avoid When You Plant Arborvitae in the Fall
Even though you can plant arborvitae in the fall, a few missteps can lead to failure.
Planting Too Late in the Season
If you wait until after the ground freezes, your arborvitae won’t have time to root.
When you plant arborvitae in the fall, do it early enough so the roots can get established.
A good cutoff is about two weeks before the soil typically freezes in your area.
If you miss that window, it’s better to container-grow your arborvitae over winter and plant in spring.
Neglecting Soil Preparation
Fall soil can be compacted from summer use.
When you plant arborvitae in the fall, loosen the soil in a wide area around the hole.
Mix in some compost to improve drainage and nutrition.
Arborvitae like slightly acidic, well-drained soil, so test your pH if you’re unsure.
If the soil is heavy clay, consider planting on a slight mound to prevent root rot.
Skipping Winter Protection
Young arborvitae are vulnerable to winter winds and heavy snow.
If you plant arborvitae in the fall, consider wrapping them in burlap or using a windbreak for the first winter.
Also, gently brush heavy snow off the branches to prevent breakage.
A little effort now saves you from a lopsided or broken arborvitae come spring.
So, Can You Plant Arborvitae in the Fall?
Yes, you can plant arborvitae in the fall, and it is often a smart choice for your garden.
Arborvitae planted in the fall establish strong roots without the stress of summer heat.
With the right timing, watering, and mulching, your arborvitae will sail through winter and burst into growth come spring.
Just avoid planting too late, prepare the soil well, and protect your young arborvitae from harsh weather.
Whether you choose Emerald Green or Green Giant, you can plant arborvitae in the fall with confidence.
Happy planting, and enjoy the evergreen beauty that arborvitae bring to your landscape all year long.
