How To Bring Back Dying Arborvitae

You can bring back dying arborvitae if you catch the problem early and take the right steps.
 
Reviving arborvitae isn’t always possible, but many trees can bounce back with proper care.
 
Knowing how to bring back dying arborvitae starts with understanding what’s causing the decline.
 
In this post, we’ll walk through the main reasons arborvitae struggle and exactly how to bring them back to health.
 
Let’s dig in and learn how to save your arborvitae before it’s too late.

How to bring back dying arborvitae: First, Identify the Problem

Before you can bring back dying arborvitae, you need to figure out what went wrong.
 
Arborvitae are tough evergreens, but they’re sensitive to certain conditions.
 
The most common issues that need your attention are water stress, pests, disease, and environmental damage.
 
Let’s look at each one so you know exactly how to bring back your arborvitae.

1. Water Stress Is the Number One Reason Arborvitae Decline

Too little or too much water can easily kill arborvitae.
 
If you want to bring back dying arborvitae, check the soil moisture first.
 
Stick your finger a few inches into the ground near the roots.
 
If it’s bone dry, your arborvitae is thirsty.
 
If it’s soggy or smells rotten, you’ve overwatered and root rot may have set in.
 
Adjusting your watering schedule is the first step to bring back dying arborvitae.

2. Pests Like Bagworms and Spider Mites

Pests can slowly drain the life from your arborvitae.
 
Bagworms create brown, cone-shaped bags on the branches and eat the foliage.
 
Spider mites cause yellowing and fine webbing.
 
To bring back dying arborvitae affected by pests, inspect the branches closely.
 
Remove bagworms by hand or use an insecticidal soap for mites.
 
Early action is key when learning how to bring back arborvitae from pest damage.

3. Fungal Diseases and Canker Infections

Fungi like Phytophthora root rot and Phomopsis tip blight can turn arborvitae brown.
 
If you see browning starting at the tips and spreading inward, disease may be the cause.
 
To bring back dying arborvitae with fungal issues, prune away infected branches and improve air circulation.
 
Avoid overhead watering that keeps foliage wet.
 
A fungicide can help if applied early in the season.

4. Environmental Stress from Wind, Salt, or Sunscald

Winter wind and road salt can burn arborvitae needles, turning them brown.
 
Sunscald occurs when bright winter sun warms the bark, then freezing temperatures damage it.
 
To bring back dying arborvitae affected by environmental stress, protect them with burlap wraps or anti-desiccant sprays.
 
Move sensitive trees away from salted driveways if possible.
 
These simple changes can help you bring back your arborvitae to full health.

Steps to bring back dying arborvitae through proper watering and soil care

Once you’ve identified the problem, take action to bring back dying arborvitae by fixing the root environment.
 
Water and soil are the foundation of any revival plan.
 
Here’s exactly what to do.

1. Water Deeply but Infrequently

How to bring back dying arborvitae that are underwatered? Give them a long, slow soak once a week.
 
Aim for at least one inch of water per week, including rainfall.
 
Use a soaker hose or drip irrigation to deliver water directly to the root zone.
 
Avoid shallow sprinkling that encourages weak surface roots.
 
Consistent deep watering helps bring back dying arborvitae by encouraging deep, healthy roots.

2. Improve Drainage for Overwatered Trees

If your soil stays wet, your arborvitae may be drowning.
 
To bring back dying arborvitae in soggy ground, dig a trench to redirect runoff.
 
Amend heavy clay soil with organic matter like compost to improve drainage.
 
Raise the planting bed if necessary.
 
Well-drained soil is essential for bringing back arborvitae that have root rot.

3. Mulch to Regulate Moisture and Temperature

Applying a 2- to 3-inch layer of bark mulch around the base of your arborvitae helps retain moisture and keep roots cool.
 
Keep mulch a few inches away from the trunk to prevent rot.
 
Mulch also reduces weed competition.
 
This simple step can make a big difference when you’re trying to bring back dying arborvitae.

Using pruning and fertilization to bring back dying arborvitae

Pruning removes dead or diseased wood so the tree can focus energy on healthy growth.
 
Fertilization gives it the nutrients it needs to recover.
 
Here’s how to use both to bring back dying arborvitae.

1. Prune Out Dead and Damaged Branches

To bring back dying arborvitae, remove all brown, brittle branches first.
 
Use clean, sharp pruners and cut back to a healthy green branch or the trunk.
 
Don’t cut into old wood that has no green needles, as arborvitae rarely regrow from bare stems.
 
Pruning in early spring or late summer gives the tree the best chance to recover.
 
This step alone can bring back dying arborvitae by redirecting energy to living parts.

2. Fertilize Gently, Not Heavily

Arborvitae don’t need much fertilizer, but a light boost can help bring back dying arborvitae.
 
Use a slow-release, balanced fertilizer (like 10-10-10) in early spring.
 
Apply half the recommended rate to avoid burning stressed roots.
 
Water well after fertilizing.
 
Over-fertilizing can hurt more than help, so be patient when trying to bring back dying arborvitae.

3. Consider Root Zone Aeration

Compacted soil starves roots of oxygen.
 
To bring back dying arborvitae in compacted areas, use a garden fork to gently aerate the soil around the drip line.
 
Or hire a professional for core aeration.
 
Better airflow helps roots absorb water and nutrients, which is critical for bringing back your arborvitae.

So, how to bring back dying arborvitae?

You can bring back dying arborvitae, but it takes correct diagnosis and consistent care.
 
First, identify whether the problem is water stress, pests, disease, or environmental damage.
 
Then adjust watering, improve soil drainage, prune dead branches, and fertilize lightly.
 
With patience and the right techniques, how to bring back dying arborvitae becomes a clear and achievable process.
 
Many arborvitae can fully recover if you act before more than half the foliage has turned brown.
 
If the entire tree is brown and brittle, it may be too late, but you now know how to bring back dying arborvitae for future plantings.
 
Hope this guide helps you nurse your arborvitae back to a vibrant, healthy state.
