Occasionally it’s necessary to remove a few limbs from your trees. First off, we would like to say that if you have tree limbs that are higher than you are able to reach, then we would strongly recommend you hire a tree professional to assist you when you remove these tree limbs. This is when you are not able to reach tree limbs safely or comfortably without risking injury to yourself.
Avoid damaging the tree collar
Now there is a few things you need to remember when you are cutting a tree limb. Where the limb meets the base of the tree is the important part. At the base of the limb, there exists something known as the ‘branch collar.’ With some trees, this collar is very distinctive and thus easy to see. However, with other trees, this collar is not as easy to find.
It’s vital that you locate this collar and avoid cutting into it at all costs when you remove a tree limb. An image of this collar are provided below.
Avoid damaging the branch bank ridge
At the base of the limb there also exists a ‘branch bark ridge.’ This is located in the ‘V’ section where the limb attaches to the tree. This is the area you must protect when removing tree limbs. You do not want to cut into this area. Why? Because this is where hormones are produced by the tree to help seal off the wound created when you cut off a limb. The tree uses these hormones to compartmentalize and seal off wounds. The tree isn’t able to replace tissue that’s been damaged when a limb is removed. Thus, you must make sure that when you make this cut, no area of the branch bark collar is affected.

Why we recommend the three cut method
When a tree limb is removed, it’s also essential to consider the weight of the limb. If you simply start to cut without supporting the weight of a limb, when you start to make your cut, the weight of the limb may cause it to suddenly drop to the ground. This unexpected drop could leave a huge tear in the tree’s bark. This tear could take the tree may months to seal off, leaving the tree vulnerable to infection or termite attack.
So how do we avoid this fate? It’s simply a matter of implementing the three-cut method.
The three cut method explained
But what is the tree cut method? In this post, we will describe how you can implement this method to ensure you do not inflict unnecessary damage to your tree when you remove a limb.
As the name suggests, the three cut method involves you making three cuts across the affected limb.
Below we outline each of these cuts:
Cut #1 of the Three Cut Method
The first cut involves making a cut around 12 inches away from the base of the limb and the tree trunk. This cut must be an undercut. Why? Because an undercut means if the limb drops to the ground under the weight of the tree during the second cut, no damage will be inflected to the bark of the tree because the first undercut will prevent the bark rip from spreading to the trunk of the tree.
Cut #2 of the Three Cut Method
The second cut is made several inches away from the third cut. Here, you cut off a large part of the limb using an overcut as illustrated in the image below:
Cut #3 of the Three Cut Method
Now the bulk of the weight of the limb should have successfully been eliminated during cut #2 above. Now you are able to make the third and final cut. This cut is made just before the branch bank collar mentioned above. It’s essential you do not cut into the collar for reasons stated above. As you cut, ensure you hang on to the remaining limb stump to ensure it does not break off and rip the bark located on the tree trunk.

The result should appear similar to the image below once the limb is finally removed:
Over time, the collar will resemble a nice round donut shape as illustrated in the image below:
The trees hormones have successfully sealed the affected area. As the tree matures, the left over limb stump will completely vanish to the naked eye.
