How To Know When An Arborvitae Is Unsavable

An arborvitae is unsavable when it displays irreversible signs like complete browning, mushy wood, and zero new growth.
 
Knowing when an arborvitae is unsavable can save you time, money, and frustration in your landscaping efforts.
 
If you’ve been wondering how to know when an arborvitae is unsavable, this post breaks down the clear indicators.
 
We’ll cover the physical symptoms that confirm an arborvitae is unsavable and when to stop nursing it back.
 
Let’s dive into the signs that tell you it’s time to say goodbye.
 

How to Know When an Arborvitae Is Unsavable

The easiest way to know when an arborvitae is unsavable is to check for three core failures.
 

1. Brown and Brittle Foliage That Doesn’t Recover

Arborvitae naturally shed old inner needles, but if the entire tree turns brown and stays brittle for months, it’s a bad sign.
 
If brushing the branches sends a shower of dead needles to the ground, that’s a major clue an arborvitae is unsavable.
 
Green arborvitae will snap back after a dry spell, but crispy brown foliage that holds its shape means the plant has shut down.
 

2. Complete Lack of New Growth Through a Full Season

An arborvitae is unsavable when it produces zero new shoots at the branch tips come spring and summer.
 
Healthy arborvitae push out soft, light green growth at the tips each year.
 
If you look closely at the ends of every branch and see nothing but old, woody stems, the tree has stopped living.
 
This is one of the most reliable ways to know when an arborvitae is unsavable because living tissue always tries to grow.
 

3. Soft or Peeling Bark That Exposes Dead Wood

Peel back a small patch of bark on the trunk or main branches.
 
If the layer underneath is brown or gray instead of green and moist, your arborvitae is unsavable.
 
Living arborvitae have a green cambium layer just under the bark.
 
When that cambium dries out and the bark falls off easily, the tree can no longer transport water and nutrients.
 
This internal rot is a definitive sign an arborvitae is unsavable.
 

Physical Signs That Confirm an Arborvitae Is Unsavable

Beyond foliage and growth, certain physical changes leave no doubt that an arborvitae is unsavable.
 

1. Mushy Trunk or Roots at the Base

Press your thumb into the trunk near ground level.
 
If it feels soft, spongy, or wet instead of firm and woody, rot has taken over.
 
Root rot from overwatering or fungus spreads quickly inside arborvitae and makes them unsavable.
 
The same goes for roots that smell sour or look black and slimy when you dig near the base.
 

2. Extensive Damage from Pests or Disease

Bagworms, spider mites, and fungal blights can destroy an arborvitae beyond recovery.
 
If more than half the foliage is gone and you see webbing, holes, or weeping cankers, the tree is likely unsavable.
 
Some arborvitae can bounce back from minor pest issues, but widespread infestation that strips the tree of needles means it’s unsavable.
 
Fungal diseases like Kabatina blight cause branch dieback that can’t be reversed once it reaches the trunk.
 

3. Deep Cracks or Splits in the Main Trunk

A vertical crack that runs deep into the wood allows disease to enter and weakens the entire structure.
 
If you see a split that exposes the inner heartwood and it doesn’t seal over, your arborvitae is unsavable.
 
This kind of damage often happens after heavy snow or ice, and it rarely heals on its own.
 

When to Stop Trying to Save Your Arborvitae

Gardening is hopeful by nature, but there’s a point where efforts become futile.
 

1. After Multiple Failed Recovery Attempts

You’ve watered deeply, applied fungicide, pruned dead branches, and fertilized lightly.
 
If you see no improvement after two full growing seasons, that arborvitae is unsavable.
 
Persistence is admirable, but a tree that doesn’t respond to care is simply done.
 

2. If the Tree Becomes a Safety Hazard

A dead or dying arborvitae can fall during a storm and damage your home, fence, or car.
 
Once you confirm that an arborvitae is unsavable, remove it quickly to prevent accidents.
 
Also, standing dead wood attracts boring insects that can spread to healthy trees nearby.
 

So, How to Know When an Arborvitae Is Unsavable?

You know when an arborvitae is unsavable by looking for brown brittle foliage, zero new growth, mushy wood, and severe pest or disease damage.
 
If most of these signs are present, the tree cannot come back no matter how much you care for it.
 
Knowing when an arborvitae is unsavable helps you make the tough call to remove it and plant something healthier in its spot.
 
We hope this guide gives you the confidence to assess your arborvitae and decide when it’s time to let go.
