When the oak tree’s roots bring the bacteria into the tree’s system, the bacteria set up shop in the tree’s core. The infected wood becomes wet and develops a gas buildup, which puts pressure on the bark until splits appear. Bacterial wetwood is also called slime flux because of this oozing.
What makes the bark of an oak tree crack?
- The goldspotted oak borer is a boring insect that produces damaging larvae that feed on woody tissue, causing bark to crack and ooze with sap. Pulling back weakened bark may reveal dense colonies of larvae, dust, excrement and pockets of sap.

Why is my oak tree bark cracking?
Newly planted trees or young trees are more prone to bark splitting. Dry weather (which slows growth) followed by wet growth conditions may cause an excessive or vigorous amount of growth leading to splits in the bark. Sunscald, especially in winter months, can cause bark injury to thin barked or young trees.
How do you treat a tree that has a split bark?
Damaged areas of the bark or limbs should not be filled with a sealer or painted. Lightly trimming the wound (tracing the injury with a sharp knife) to help the tree compartmentalize the exposed area and wrapping the damaged area with a light-colored tree wrap can help accelerate the healing process.
What causes splits in tree bark?
The most common cause for splitting tree bark is from frost cracking or “sun scald.” Sun Scald most often occurs on the south to southwest side of tree trunks on young trees with thin bark. On a warm winter days, the direct sun’s heat warms up the surface of the bark. Later that night, these areas rapidly re-freeze.
What does a crack in a tree trunk mean?
Cracks in tree trunks can be one of the major indicators of an unstable tree. Most cracks are caused by improper closure of wounds or by the splitting of weak branch unions. They can be found in branches, stems or roots, and vary in type and severity.
What does a diseased oak tree look like?
Conks are initially white or light-colored and turn black and crusty with age. Infected trees show symptoms of general tree decline including branch dieback, loss of leaves and yellowing or browning of leaves in summer. Trees weakened by drought stress, wounding or other injuries are most susceptible.
Can you save a tree with split bark?
It’s often possible to repair a damaged tree trunk that has not split apart and fallen completely. Trees that exhibit minor splitting at the base of the trunk, such as co-dominant trees pulling apart or bark splitting open, can still be saved.
Can a tree survive a split trunk?
Can a tree survive a split tree trunk? It is possible to save a split tree trunk if the split is not extensive. You can use nuts and bolts to join the split trunk to help it heal. If the tree’s damaged area is less than 25% of the trunk’s circumference, it can heal gradually and survive.
Can trees repair themselves?
When a tree is wounded, the injured tissue is not repaired and does not heal. Trees do not heal; they seal. If you look at an old wound, you will notice that it does not “heal” from the inside out, but eventually the tree covers the opening by forming specialized “callus” tissue around the edges of the wound.
How can I help my tree heal?
Good pruning practices are a much better plan to help trees heal. Make clean cuts flush with the trunk of the tree when removing large branches. Straight cuts leave smaller wounds than angled cuts, and smaller wounds are more likely to callus over promptly. Cut broken limbs with ragged ends below the point of injury.
Can you save a cracked tree?
How to Save a Split Tree. Minor splits on branches that are not hanging or otherwise deformed should heal on their own. If the split looks like a gash and is still connected to an unharmed branch, smooth the bark out to help the healing process.
What is it called when a tree splits?
A tree fork is a bifurcation in the trunk of a tree giving rise to two roughly equal diameter branches.
