Should you seal a tree wound?

In most cases, it is best to simply let wounds seal on their own. Over millennia, trees have developed effective mechanisms for this. Unlike people or animals, woody plants are unable to heal damaged tissues. Instead, they compartmentalize wounds with layers of cells that prevent damage from spreading any further.

Why is my maple tree splitting?

Maples are thin-barked trees and prone to splitting in a cold winter. The fact that your damage is on the south side also adds up since the sun tends to warm that part of the tree the fastest on winter mornings. (Sudden thawing of frozen sap is what causes winter splits.)

How do you repair a damaged tree trunk?

When a tree is wounded, the injured tissue is not repaired and does not heal. Trees do not heal; they seal.

Reasons for Frost Crack in Trees. Frost is just one of the causes of tree bark cracking. You’ll also see cracking tree trunks from a condition called sunscald.

What causes a tree to crack?

What causes a tree to split?

High winds, lightning, heavy snowfall that weighs down branches, hail and ice storms can all injure a tree, often resulting in broken or split branches, uprooting or even trunks split down the middle. Wounds such as a divided trunk not only affect a tree's appearance, but also can allow fungal infections to develop.

How to tie a split tree?

Pull the split halves of the trunk together by hand if working on a small or young tree, and tie them together at the top of the split with a length of rope. For thick trunks not easily manipulated by hand, use a block-and-tackle pulley placed a few feet above the split, hooking the upper portion on a horizontal-growing limb.

How to tie a tree together?

Do trees spread if they are fast?

If the tree is fast and effective with its boundary-setting mechanisms, the infection remains localized and does not spread. However, if the boundary-setting mechanisms are not effective, the infection will spread. Most vigorous or actively growing trees are fairly successful in coping with decay-spreading mechanisms.

Step 1

ASSESS SPLIT -- Is there enough bark on each side of the split? If not, then the side with little or no bark will eventually die, since the part directly under the bark is what feeds the branches and leaves.

Step 2

DETERMINE SUPPORT -- You need to be able to force the split back together somehow, and hold it in place for several years as the tree grows around the split. For larger trees, you can do this with a winch and rope or cables (B) to winch the halves back together above the split.

Step 3

APPLY GLUE -- With the support method determined, I opened up the split and used a popsicle stick to apply the glue to both sides of the split. You can see the glue starting to expand and fill in the space in the picture.

Step 4

PROVIDE SUPPORT -- Then, I tied the branches above the split so that I could pull the split back together so that the glue can cure. I wrapped some twine around the trunk temporarily while the glue sets up and hardens. I will remove this in a day, since I don't want to girdle and kill the tree.

Step 5

INSTALL BOLT/NUT -- I have to admit now, after several weeks the glue did not hold. The trunk will need to be held together for a couple seasons so that the bark will grow around the split. So I held the trunk together and used a spade drill bit to drill a 3/16" hole through the trunk.

Why a Healthy Trunk Is Important

Like any living creature, a tree’s life depends on maintaining a delicate state of equilibrium. Without the right amount of light, water, and nutrients, it won’t be able to survive and grow tall. As you may remember from science class, a tree’s trunk is a vital part of its biological function.
