Should I Remove a Storm-Leaning Tree? Yes, If...

Yes, you should remove a tree that is leaning after a storm if the lean appeared suddenly, if the root plate is lifting or the soil around the base is cracked, or if the trunk has a visible split. A tree that has always leaned slightly and shows no new damage can often stay, but any new lean after a storm is a structural failure that will not repair itself. The weight of the tree is now off balance, and the roots that anchor it have lost their grip. That combination makes the tree likely to fall, and it can fall without warning on a calm day.

Start by looking at the base of the trunk. If you see soil pushed up on one side and a gap or depression on the other, the root system has moved. That is the most reliable sign that the lean is dangerous. A lean of more than 15 degrees from vertical is also a reason for concern, even if the roots look intact. When a tree leans after a storm, the force of the wind has stretched or torn the roots. The tree may stand for weeks, but it is no longer anchored the way it was.

If the tree is small, say under 10 feet tall, and the roots are still mostly in the ground, you may be able to push it back upright and stake it. That only works for young trees with a trunk diameter under 4 inches. For anything larger, removal is the safe choice. A leaning tree that stays upright is still a hazard. It can fall onto your house, a fence, a power line, or a person. The cost of removal is far less than the cost of the damage the tree could cause.

You need to remove a leaning tree when any of these three conditions are present: the root plate is visibly lifted, the trunk has a crack or split, or the lean is new and more than 15 degrees. Each of these means the tree has lost its structural integrity. No amount of cabling or bracing will restore a tree that has pulled its own roots out of the ground.

Here is what each condition looks like:

• Lifted root plate: The soil on one side of the trunk is raised, and you can see roots exposed on the opposite side. The tree is literally tipping over.
• Trunk crack or split: A vertical crack in the trunk, especially one that goes deep into the wood, means the trunk may break in half. A leaning tree with a crack is at high risk of snapping.
• New lean over 15 degrees: If the tree was straight before the storm and now leans noticeably, the roots have moved. Even if the soil looks flat, the internal roots may be torn.

If you see any of these, do not wait for the tree to fall on its own. Keep people and pets away from the area, and call a tree removal service. A professional crew will assess the tree and recommend removal if it is not safe to save.

You can keep a leaning tree if the lean is old, the tree is healthy, and the roots are intact. A tree that has grown at an angle for years has developed reaction wood that strengthens the trunk and roots to support the lean. This is common on slopes or in windy areas. If the lean has not changed and there are no cracks or root problems, the tree is likely stable.

To decide whether to keep a leaning tree, ask yourself these questions:

• Was the tree leaning before the storm? If you have photos or remember it leaning, that is a good sign.
• Are the roots visible or the soil cracked around the base? If not, the root system may be intact.
• Is the trunk free of cracks, splits, or hollow sounds when tapped? A solid trunk is a good sign.
• Is the tree a species that commonly leans, such as a pine or a willow? Some species naturally grow at an angle.

If you answered yes to most of these, the tree may be safe to keep. But if you are unsure, have a professional look at it. A tree that has a hidden root injury can fall months later. An inspection by a certified arborist or an experienced tree crew can give you a confident answer.

Removing a leaning tree is more complex than cutting a straight tree, because the weight is pulling in one direction. The crew must control the direction of the fall to avoid hitting your house, a fence, or a power line. They often use ropes and pulleys to guide the tree down safely. The work requires skill and experience, not just a chainsaw.

Here is a typical process for removing a leaning tree:

1. Inspection: The crew examines the tree, the lean direction, the surrounding structures, and the condition of the roots and trunk. They decide the safest way to bring it down.
2. Setting up ropes: If the tree is near a structure, the crew will attach ropes high in the canopy. These ropes allow them to pull the tree in a controlled direction as it falls.
3. Making the cut: The crew makes a notch cut on the side facing the intended fall direction, then a back cut on the opposite side. For a leaning tree, the back cut must be deeper to allow the tree to rotate.
4. Controlled fall: The crew pulls on the ropes as the tree begins to fall, guiding it away from hazards. In some cases, they may lower the tree in sections to avoid any risk of hitting something.
5. Removing the stump: After the tree is down, you can choose to have the stump ground out or left in place. Stump grinding is a separate service that costs extra.

The cost of removal depends on the tree's size, its location, and the difficulty of the job. A large tree near your house will cost more than a small tree in an open yard. Ask for a written estimate before work begins. The estimate should include the cost of cutting, hauling, and cleanup, and whether stump grinding is included.

If you have a leaning tree after a storm, the first step is to keep everyone away from the area. Do not stand under the tree or near the root plate. The tree can fall at any moment, especially if the wind picks up again. Then, look at the tree from a safe distance to assess the damage. Take photos of the lean, the roots, and any cracks. This will help when you call a tree service.

Next, check if the tree is leaning toward your house, a power line, or a neighbor's property. If it is, call a tree removal service immediately. Do not attempt to remove the tree yourself. A leaning tree is unpredictable, and cutting it wrong can cause it to fall in the wrong direction. Professional crews have the training and equipment to handle the risk.

If the tree is not near anything valuable, you may have time to get a few quotes. But do not delay for days. A lean that looks stable today can worsen with the next rain or wind. The longer you wait, the higher the risk of the tree falling on its own.

In Knoxville, you may need a permit to remove a tree, depending on the tree's size and location. The city has regulations to protect certain trees, especially large ones. You should check with the Knoxville City Arborist's office before removing any tree. They can tell you if a permit is required for your specific tree.

Permits are typically required for trees with a diameter over 6 inches when measured at 4.5 feet above the ground. However, there are exceptions for dead, dying, or hazardous trees. A tree that is leaning dangerously after a storm may qualify for an exemption, but you still need to get approval in advance. If you remove a protected tree without a permit, you may face fines.

When you call a tree removal service, ask if they handle the permit process. Many services will help you obtain the necessary permits as part of the job. If they do not, you will need to apply for the permit yourself. The process usually involves an inspection by the city to confirm the tree is a hazard.
