How to Save a Dying Arborvitae Tree

When you’re figuring out how to save a dying arborvitae tree, the first thing is to assess the symptoms.
 
Browning needles, bare branches, and drooping tops are all signs your arborvitae is struggling.
 
Here are the key actions to take when saving a dying arborvitae.
 

1. Water Deeply and Consistently

One of the fastest ways to save a dying arborvitae is to fix your watering routine.
 
Arborvitae trees need about 1–2 inches of water per week, especially during dry spells.
 
If your tree is dying, check the soil moisture a few inches down.
 
Dry soil means you need to water deeply, letting the water soak into the root zone.
 
Overwatering can also cause root rot, so make sure the soil drains well.
 
Consistent watering is critical for how to save a dying arborvitae tree.
 

2. Inspect for Pests and Diseases

Another common reason your arborvitae tree is dying is pest infestations.
 
Spider mites, bagworms, and arborvitae leaf miners can suck the life out of your tree.
 
When saving a dying arborvitae, look for tiny webs, small bags, or yellowing needles.
 
Treat pests with insecticidal soap or neem oil, and prune away heavily infested branches.
 
Diseases like Phomopsis blight or root rot also cause dieback.
 
Proper diagnosis is key to how to save a dying arborvitae tree.

3. Improve Soil and Drainage

Arborvitae trees hate sitting in waterlogged soil.
 
If your arborvitae is dying and you have clay soil or poor drainage, that’s likely the culprit.
 
When saving a dying arborvitae, consider amending the soil with organic matter or installing drainage.
 
Raised beds or planting on a slight slope can also prevent water from pooling.
 
Healthy roots mean a healthier tree, so this step is vital for how to save a dying arborvitae tree.
 

Common Causes of Arborvitae Decline

To fully understand how to save a dying arborvitae tree, you need to know what causes the decline in the first place.
 
Here are the usual suspects.
 

1. Drought Stress

Arborvitae trees are shallow-rooted and suffer quickly during drought.
 
If your arborvitae tree is dying after a hot summer, lack of water is the likely cause.
 
Brown leaves often start from the inside and move outward.
 
Deep watering during dry periods is essential for saving a dying arborvitae from drought.
 

2. Winter Burn

Cold, drying winds can desiccate arborvitae foliage, causing it to turn brown.
 
Winter burn is common on the south and west sides of the tree.
 
When saving a dying arborvitae after winter, prune off damaged branches in spring.
 
Wrap vulnerable trees in burlap for future winters to prevent this.
 

3. Improper Planting Depth

Planting an arborvitae too deep can suffocate the roots and lead to a dying arborvitae tree.
 
The root flare should be visible at the soil surface.
 
If you’re solving how to save a dying arborvitae, you may need to gently expose the root crown.
 
Proper planting depth is a simple fix that often works.
 

4. Nutrient Deficiencies

Lack of essential nutrients like nitrogen or iron can cause yellowing and decline.
 
If your arborvitae tree is dying and the soil is poor, apply a balanced fertilizer in spring.
 
Slow-release formulas work best for saving a dying arborvitae over time.
 

Revival Steps for a Dying Arborvitae

Once you’ve identified the cause, you can take targeted steps to save a dying arborvitae tree.
 

1. Prune Dead and Diseased Branches

Use clean, sharp pruners to remove all brown, brittle wood.
 
Cut back to healthy green growth or the main trunk.
 
Pruning helps the tree focus energy on new growth and is a key part of how to save a dying arborvitae.
 
Dispose of infected branches to prevent disease spread.
 

2. Apply Mulch Around the Base

A 2- to 3-inch layer of organic mulch helps retain moisture and regulate soil temperature.
 
When saving a dying arborvitae, keep mulch a few inches away from the trunk to avoid rot.
 
Mulch also suppresses weeds that compete for water and nutrients.
 

3. Fertilize Carefully

Use a slow-release fertilizer designed for evergreens.
 
Avoid high-nitrogen formulas that can burn stressed roots.
 
Fertilizing in early spring or late fall gives your arborvitae the best chance when you’re saving a dying arborvitae.
 

4. Provide Winter Protection

If winter burn is a recurring issue, wrap your arborvitae in burlap or set up a windbreak.
 
This simple step can prevent future decline and is part of the long-term plan for how to save a dying arborvitae tree.
 
Anti-desiccant sprays can also help reduce moisture loss.
