How to Straighten a Tree That’s Leaning in Your Yard
Straighten things out once and for all
The Leaning Tower of Pisa might be a wonder to look at, but when it comes to the trees in your yard, it’s less than ideal. In some cases, you can learn how to straighten a tree DIY-style, but in other situations, you might need the help of a professional tree maintenance service. Here’s what you need to know to make the best decision about your tree.
How to Straighten a Young Tree
In order to straighten out a young tree, staking is the preferred method. Follow these guidelines for straightening a young tree:
1. Install Stakes
To set up your straightening stakes, you’ll need to drive three one- to three-foot-tall stakes into the ground around the sapling with a sledge hammer. Be sure to install them at a slight angle away from the tree trunk.
2. Push Into Position
Then, grab a hold of the young tree and push on it to straighten it. You should feel the whole tree move, not just the top of the trunk.
3. Tie Off the Stakes
Finally, use some gardening twine to tie the tree off to the stakes, just a little above the ground. Using some rubber hose tubing or similar material around the twine where it makes contact with the trunk to protect the bark from damage.
How to Straighten a Mature Leaning Tree
You’ll want to have the following tools on hand before you begin:
Sledgehammer
Tree straps or a cable with a rubber hose
Three 5–8-foot stakes (metal or wood)
Shovel
There are also tree straightening kits available for purchase that include the straps and stakes, though you still provide the tools. Once you gather everything up, you’re ready to start straightening a leaning tree with the steps below.
1. Inspect the Tree
Before straightening your tree, it’s a good idea to evaluate the tree’s condition. Generally speaking, you can DIY straightening a sapling or smaller tree, but if your tree is mature and on the larger side, you might need a professional to use machinery to pull the tree back in place.
Even if you’re straightening a small tree, you’ll need to use extreme caution here. Work with a partner, only go out in good weather, and have a plan if things go wrong and the tree begins to fall.
2. Install Your Stakes
Start by hammering a stake opposite the leaning tree, hammering it into the ground about 18 inches away, 18 inches deep, and at a 15-degree angle directed away from the tree.
Do not hammer into the tree roots. If you feel resistance, try moving the stake slightly further away. Install the other stakes in a triangular shape on the outside of the tree, also opposite the direction the tree is leaning. The deeper you drive your stakes, the better the reinforcement. Just be sure to avoid driving them in too deeply to remove them once your tree is straight.
3. Straighten the Tree
If you’ve got a bigger tree on your hands, then it’s time to phone a friend for this one. You and a partner will want to push the tree back into alignment by pressing on the trunk. If your tree doesn’t straighten fully, that’s OK. Spraying the ground around the tree with a garden hose might be a good idea to make the job a little easier.
If the tree is exceedingly large, or just won’t budge, you’ll definitely want to hire a pro.
4. Tie the Tree
Once your tree is relatively straight, place the tree strap or hose and cable around the tree and then secure it around the stake. Repeat with the other stakes, tightening securely. As your strap loosens, tighten it again.
Note: You’ll want to check the tightness of the stakes every week and after storms to ensure that it’s still taut. Leave the tree tied to the stakes for around a year to ensure it stays straight.
How to Replant and Straighten an Uprooted Tree
You should only attempt to replant a small uprooted tree and you’ll definitely need the help of some friends. Be sure to wait for good weather and only attempt this work if you’re confident you can do it safely.
1. Inspect the Tree
Your tree must have no less than one-half of its root system intact for replanting and straightening an uprooted tree. The uprooted roots also cannot be majorly damaged, or the tree might not survive.
There’s also the matter of the soil on the replanting end. The best time to complete these steps is when the soil is moist and pliable, which is nearly guaranteed in the spring. However, no matter the season, make the soil more pliable by giving it good spraying from the garden hose.
2. Remove the Soil
Before transplanting an uprooted tree, you’ll need to dig out the soil underneath the roots to allow for tree realignment. Be sure to take out as much soil as you can to give the roots space for when you straighten the tree or you’ll risk damaging the roots. Go slowly here and work carefully to avoid transplant shock, as trees include massive root systems that deliver nutrients and help maintain stability. In other words, you want enough room for the roots and root ball while leaving enough soil to help with the transition.
3. Adjust Into Place
The replanting process is best suited for small or medium-sized trees, and this step is why. Adjusting the tree into place is slow and arduous work, so have some friends with you for assistance. Slowly lift and adjust the tree into a straight position by hand, being mindful of how the roots appear as you pull the tree back into place. Ensure that all roots and the associated root ball are below the ground—you don’t want any poking up into the air when it’s time to add soil.
Again, this step is a big reason why only working with small trees is so important. Never try to lift or move a large tree without a pro.
4. Add Soil and Tamp Down
Speaking of soil, once you’ve properly adjusted the tree and it looks straight, you should begin adding a new layer of soil. Make sure to fill in the entire gap over the root ball and cover every root in the system with dirt. Once you are satisfied, begin firmly tamping down the soil. You want it to be compact so that your tree won’t move out of place again. Finally, add some water to the newly packed soil to feed those roots.
5. Stake It
Lastly, stake your tree by driving stakes into the ground and attaching them to support wires and straps. Your stake should be at least 5 feet long and approximately 15 to 18 inches from the tree trunk, with around 18 inches of the stakes hammered into the ground. Make sure only the strap comes into contact with the tree trunk, as bare wire, cables, and rope all damage the bark.
Canvas hammock straps or burlap straps are the least invasive options here for long-term support and fen come and feel free to run lengths of rubber garden hose from the strap, attaching the rope or cables to the hose instead of the strap itself to further minimize the chances of these materials rubbing against the bark. Finally, give any ropes used to secure the tree a small amount of slack to allow the trunk to move if needed.
6. Prune and Wait
You are just about finished here. Once staked and properly supported, conduct minor pruning of any damaged tree branches during the inciting event (storm or otherwise.) Only prune broken branches at this stage. Wait until later for any serious cosmetic adjustments.
To that end, wait until the tree has established new growth before going in for more pruning. Generally speaking, a root system takes a full year to re-establish itself per inch of trunk diameter. This time frame varies depending on the type of tree and the extent of the previous damage. As you wait for the root system to extend deep into the soil, fertilize and water the tree as necessary.
What If Your Tree Is Too Big or Uprooted?
In some cases, you won’t be able to straighten a bent tree by yourself. Two possible scenarios include large mature, leaning trees and uprooted trees. If your tree is large or uprooted, you’ll need special equipment and knowledge of how to replant the tree’s roots.
To save your tree, the root ball will need to be intact. If it is, and you can tether the tree via a cable, then you can likely straighten the tree. This isn’t a do-it-yourself job, though. It will likely involve specific tools and techniques that require an expert’s touch. Trying to attempt this on your own can be very dangerous.
DIY vs. Hiring a Pro
A tree maintenance service near you is your best bet for examining your tree and determining whether they can straighten it. An arborist’s goal is to save trees rather than remove them, and they’re generally eager to share their knowledge about how to keep trees healthy. If there’s no hope for your tree, they’ll break the news to you, too. Get at least three estimates before you decide how to proceed. Many local tree services have arborists on staff, so they can offer advice for saving trees, as well as their safe removal.
Leaning Tree Causes
Knowing why your tree is leaning can help you prevent it from happening again. Here are a few reasons why you might have a leaning tree:
You have a newly planted sapling that hasn’t established a robust root system yet.
You live in a wet, stormy climate where the weather makes the soil too soft.
Strong winds, rain, snow, and ice continuously pull at the branches of your tree.
The soil conditions on your property are too porous to secure the root system—think sandy soil.
Conversely, the soil conditions are too compact for the roots to anchor into the soil—think clay soil.
The sapling wasn’t planted deep enough.
The soil wasn’t tamped down when the tree was planted.
The tree was planted at an angle.
The crown of your tree is imbalanced.
The roots were damaged via digging, trenching, tilling, drought, fertilizers, pesticides, or other environmental factors.
Your tree is infected or diseased.
How to Prevent a Tree From Leaning
Proper tree management is the best way to prevent your yard from looking like a vertical game of pick-up sticks. If the pro successfully straightens the tree, it will require extensive time to recover and become stable again—sometimes three to five years—so it’s important to do the job safely and regularly inspect your tree.
You can prevent your trees from leaning by:
Checking the tension on the cables of your newly staked tree
Applying a tree growth regulator
Covering the root ball with extra mulch leading up to winter
Following best practices for planting a tree
Pruning your trees
Enhancing your soil
Avoiding synthetic fertilizers
When Is the Tree Beyond Saving?
If you’ve tried staking your tree and, come time to remove the straps, it does not hold its weight, then it may be time to call in a pro to assess the situation. Trees that you cannot straighten after a fall, mature and completely uprooted trees, or those whose roots are significantly damaged may require removal, as they present a safety hazard if left standing.

Frequently Asked Questions
Trees naturally want to grow upward, so one may straighten all by itself, though this only comes into play when a tree is leaning just a small amount. For trees growing into an awkward position or those leaning heavily in one direction, the above steps are necessary to ensure the tree gets back on the right path. This also holds true for trees planted in a spot with unstable soil.
A tree leaning in one direction may eventually fall over if gravity has its way, making leaning trees more of a hazard than vertically-growing plants. A sudden lean indicates the weakening of the roots, leading to potentially dangerous encounters. Not all leaning trees are dangerous, but you should hire a pro to inspect most leaning trees thoroughly to avoid any mishaps down the line.
Trees that have grown with a lean for years are not dangerous, though the added weight to one side could cause an issue eventually. Things are more tricky with trees that seemingly developed a lean overnight. If one of these plants is leaning more than 15% from vertical, consider transplanting or straightening the tree.
