If your arborvitae is leaning due to wind, soil settlement, or a heavy snowfall, you can often fix it without too much trouble.
Learning how to straighten a leaning arborvitae starts with understanding why it’s leaning in the first place.
In this post, we’ll cover the steps to straighten a leaning arborvitae, the best tools and methods, and when to step back.
Let’s dive into how to straighten a leaning arborvitae so your tree stands tall again.
How to Straighten a Leaning Arborvitae: The First Steps
Before you grab stakes and rope, you need to know what kind of lean you’re dealing with.
Here’s how to straighten a leaning arborvitae by starting with a proper assessment.
1. Check the Severity of the Lean
If the lean is less than 15 degrees from vertical, you can usually straighten a leaning arborvitae on your own.
A lean greater than 45 degrees might mean the root system is damaged and needs professional help.
To straighten a leaning arborvitae safely, never force a tree that’s uprooted or has cracked soil around the base.
2. Examine the Root Ball
A leaning arborvitae often has a tilted root ball.
Gently press around the base to see if the roots are still holding soil firmly.
If you can rock the tree easily, the root ball may have loosened, and straightening a leaning arborvitae will require re‑anchoring.
3. Wait for the Right Season
The best time to straighten a leaning arborvitae is early spring or fall when the ground is moist and workable.
Avoid doing this during summer heat or frozen winter ground, as the tree may not recover.
Patience matters when you’re learning how to straighten a leaning arborvitae effectively.

Methods to Straighten a Leaning Arborvitae
Once you’ve assessed the situation, you can choose the best technique to straighten a leaning arborvitae.
Below are three common methods that work for most home landscapes.
1. Staking a Leaning Arborvitae
Staking is the simplest way to straighten a leaning arborvitae if the roots are still intact.
Drive two or three wooden or metal stakes into the ground outside the root zone.
Use soft tree ties or old pantyhose to attach the trunk to the stakes, pulling gently upright.
Leave the ties loose enough to allow slight movement, which helps the tree build strength.
Check every few weeks and adjust tension as needed to fully straighten a leaning arborvitae.
2. Tensioning with a Guying System
For taller arborvitae, guying (anchoring with ropes and ground anchors) helps to straighten a leaning arborvitae more securely.
Insert screw‑in ground anchors at a 45‑degree angle away from the lean direction.
Attach strong rope or wire (covered with garden hose to protect the bark) from the tree to the anchors.
Gradually tighten the tension over a few weeks to straighten a leaning arborvitae without shocking the roots.
3. Repositioning the Root Ball
If the root ball has shifted, you may need to straighten a leaning arborvitae by digging it out and repositioning it.
Carefully dig around the root ball, loosen the soil, and gently tilt the tree back to vertical.
Backfill with native soil and water deeply to settle the roots.
This method is more invasive but can effectively straighten a leaning arborvitae when stakes alone won’t work.
Aftercare to Keep Your Arborvitae Straight
Once you’ve managed to straighten a leaning arborvitae, proper aftercare ensures it stays upright.
1. Water Consistently
Water your arborvitae deeply once a week during dry spells.
Moist soil encourages root growth that will anchor the tree and help straighten a leaning arborvitae permanently.
Avoid overwatering, as soggy roots can weaken the hold.
2. Mulch Around the Base
Apply a 2‑3 inch layer of mulch, keeping it a few inches away from the trunk.
Mulch retains soil moisture and prevents temperature swings that could cause the tree to lean again.
This simple step supports your effort to straighten a leaning arborvitae.
3. Remove Stakes After One Growing Season
After a full season, the tree should have enough roots to stand on its own.
Remove stakes and ties to allow natural movement, which strengthens the trunk.
Leaving stakes too long can actually make the tree dependent on them, defeating the goal to straighten a leaning arborvitae for good.
When to Call a Professional for a Leaning Arborvitae
Not every lean can be fixed with DIY methods.
If the arborvitae is older than 10 years with a thick trunk, straightening a leaning arborvitae might require heavy equipment.
If you see large cracks in the soil, exposed roots with minor tears, or the lean suddenly worsens, call an arborist.
They have the tools and experience to straighten a leaning arborvitae without causing further damage.

To straighten a leaning arborvitae, you start by assessing the lean severity, checking roots, and choosing the right season.
