Can Arborvitae Be Planted In Fall

Arborvitae can be planted in fall and it’s actually one of the best times to get them in the ground.
 
Planting arborvitae in fall gives the roots a head start before winter arrives.
 
If you’ve been wondering can arborvitae be planted in fall, the short answer is yes with a few important caveats.
 
Fall-planted arborvitae often establish better than those planted in the heat of summer.
 
The cooler temperatures and consistent autumn rains create ideal conditions for root growth.
 
In this post, we’ll explore why you can plant arborvitae in fall, how to do it right, and what to avoid.
 
Let’s dig into the details of fall planting for arborvitae.
 

Why Arborvitae Can Be Planted in Fall

Arborvitae can be planted in fall because their root systems respond well to cool, moist soil.
 

1. Cooler Temperatures Reduce Transplant Shock

When you plant arborvitae in fall, the air is cooler and the sun is less intense.
 
This means less evaporation from leaves and less stress on the young tree.
 
Transplant shock is minimized because the tree isn’t trying to support new top growth.
 
Instead, all its energy goes into root establishment.
 
That’s a major reason why fall-planted arborvitae often outperform spring-planted ones in the first year.
 

2. Soil Is Still Warm Enough for Root Growth

Even though the air cools down in fall, the soil stays warm for several weeks after the last heat wave.
 
Warm soil encourages roots to spread out and anchor themselves before winter.
 
Planting arborvitae in fall means the roots can grow until the ground freezes.
 
This head start helps the tree survive winter dry spells and emerge stronger in spring.
 

3. Natural Rainfall Reduces Watering Work

Fall usually brings more consistent rainfall than summer.
 
When you plant arborvitae in fall, you rely less on manual watering.
 
The soil stays evenly moist, which roots love.
 
Overwatering is less of a risk because rain comes in gentle doses.
 
You still need to water during dry spells, but fall weather does much of the work for you.
 

4. Less Competition from Weeds and Pests

Weeds slow down in fall, and many insect pests go dormant.
 
This gives fall-planted arborvitae a cleaner start.
 
You don’t have to worry about aggressive weeds stealing moisture or nutrients.
 
And common arborvitae pests like bagworms and spider mites are less active.
 
Planting arborvitae in fall means the tree can focus on rooting, not fighting.
 

Best Practices for Planting Arborvitae in Fall

If you decide to plant arborvitae in fall, follow these tips to ensure success.
 

1. Time Your Planting Right

Aim to plant arborvitae at least six weeks before the first hard freeze in your area.
 
This gives roots enough time to establish before the ground becomes rock solid.
 
Check your local frost date and count backward.
 
Planting too late in fall can leave roots vulnerable to frost heave.
 
So timing matters for fall-planted arborvitae.
 

2. Prepare the Soil Well

Arborvitae prefer well-draining soil with a slightly acidic to neutral pH.
 
Dig a hole twice as wide as the root ball but no deeper than the root ball itself.
 
Loosen the soil around the hole so roots can spread easily.
 
You don’t need to add fertilizer at planting time.
 
Fall-planted arborvitae shouldn’t be pushed to grow new foliage; they need roots first.
 
Mix in some compost if your soil is heavy clay to improve drainage.
 

3. Water Deeply After Planting

Immediately after planting arborvitae in fall, give it a deep soaking.
 
Water slowly so moisture penetrates the entire root zone.
 
Continue watering weekly if rain is scarce until the ground freezes.
 
Don’t let the soil dry out completely, but also avoid soggy conditions.
 
Proper fall watering sets the stage for a healthy tree.
 

4. Mulch to Insulate Roots

Apply a 2- to 3-inch layer of organic mulch around the base of the tree.
 
Keep mulch a few inches away from the trunk to prevent rot.
 
Mulch acts like a blanket for the roots, moderating soil temperature.
 
It also holds in moisture and suppresses winter weeds.
 
Fall-planted arborvitae benefit greatly from this simple step.
 

Common Mistakes When Planting Arborvitae in Fall

Even though arborvitae can be planted in fall, mistakes can still happen.
 

1. Planting Too Late in the Season

If you plant arborvitae just before a hard freeze, roots won’t have time to grow.
 
The tree then enters winter with a weak root system.
 
It may suffer from winter burn or even die back.
 
Always give yourself that six-week window.
 
Planting arborvitae in fall too late is the number one mistake.
 

2. Overwatering After Leaves Drop

After deciduous trees lose leaves, they need less water.
 
But arborvitae are evergreen, so they continue to lose moisture through their foliage.
 
A common mistake is to stop watering too soon.
 
Conversely, overwatering in cool, wet fall can lead to root rot.
 
Check soil moisture with your finger before watering.
 
Balance is key for fall-planted arborvitae.
 

3. Skipping Winter Protection

Young arborvitae planted in fall may need some winter protection.
 
Windburn and heavy snow can damage branches.
 
Consider wrapping the tree with burlap or installing a windbreak.
 
If you live in an area with heavy snow, gently brush it off after storms.
 
Protecting fall-planted arborvitae ensures they come through winter healthy.
 

So, Can Arborvitae Be Planted in Fall?

Arborvitae can be planted in fall, and it’s a smart choice for many gardeners.
 
Fall-planted arborvitae enjoy cooler temperatures, warm soil, and natural rainfall.
 
They root in quickly and face fewer pest and weed issues.
 
Just be sure to plant at least six weeks before a hard freeze, water deeply, and mulch well.
 
Avoid common mistakes like planting too late or overwatering.
 
With the right timing and care, planting arborvitae in fall gives your tree a strong start.
 
So go ahead and get those arborvitae in the ground this autumn.
