When fungus causes a disease to spread inside an oak, the center of the trunk and branches can decay. As the rot progresses, it creates hollow pockets that prevent the oak’s ability to move water and nutrients, which effectively starves the tree.
Why does my oak tree have a hollow at the base?
- We have quite a few oaks (white or red) with with hollows where trunks or branches broke off years ago forming “cups” that hold water long after each rain, and others where a pool was formed at the base where 3 or 4 trunks merge together.

What does it mean if a tree branch is hollow?
A tree hollow is a cavity in a living tree. Tree holes can be caused when an injury to the tree, such as breakage of a limb, creates an opening through the bark and exposes the sapwood. The sapwood is attacked by fungi and bacteria, which form a cavity in the bole of the tree.
Is it normal for oak trees to have dead branches?
Count the Dead Branches An oak tree that displays 10 percent or fewer dead branches may simply be going through a natural stage of growth and renewal. Dead branches are a normal occurrence in healthy trees, and the absence of leaves is not always a sign of a dead branch.
What are the signs of a dying oak tree?
5 Signs that Your Oak Tree is Dying
- Yellow Leaves. Have you noticed yellow leaves with greenish-colored veins on your oak tree?
- Foliage Loss. Oak trees are bound to lose at least some of their foliage, especially when the cool fall and winter weather arrives.
- Decaying Bark.
- Powdery Mildew.
- Rotted Roots.
Can a hollow tree be saved?
The recommended method for patching a tree hole is to use a thin metal flap or screening covered with plaster over the tree hole. This will prevent animals and water from entering the hole and create a surface that the bark and outer living layers can eventually grow back over.
How do you know if a tree should be removed?
Vertical cracks, seams, dead branch stubs and large, older wounds suggest internal decay. Severe damage to the main trunk often warrants removal of the tree. If the damaged area is less than 25 percent of the circumference of the trunk, the wound could gradually heal over and no permanent injury should result.
What can I do with a hollow tree?
Hollow trees can be left open or the cavity may be filled. If the hollow is left open, do not drill a hole to allow water to drain as this is an additional wound to the tree. Do not use concrete as a fill material as it will not move with the trunk resulting in more injury.
How do I know if my oak tree is healthy?
Try scraping the bark in multiple areas on the tree. A healthy oak tree will have green coloration. If it reveals a yellow or brownish color underneath, the tree is mostly likely dying or dead.
What is the best fertilizer for oak trees?
For oaks, a ratio of either 12-4-8 (12% Nitrogen, 4% Phosphorus, and 8% Potassium) or 12-6-6 is recommended. A fertilizer that releases nitrogen too quickly can cause more harm to the soil and tree than good.
What does the oak tree symbolize?
Well known for its beautiful, lobed green leaves and tiny acorns, the oak is cherished across the world as a symbol of wisdom, strength and endurance.
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.
How can I help my dying oak tree?
To save a dying oak tree, employ the following tactics:
- Prune and discard any diseased branches.
- Spray diseased areas with fungicide.
- Inject fungicide into your oak tree.
- Fertilize your tree.
- Mulch near the base of your tree.
- Ensure your tree is not overwatered. Dig drainage ditches if the tree is in boggy ground.
Should I remove a hollow tree?
A tree with a hollow trunk has been seriously compromised and is a hazard. If a third of the tree is rotted or hollow inside, it needs to be removed. The tree is suddenly leaning. All leaning trees aren’t necessarily dangerous, but a tree that suddenly leans to one side may have structural problems.
What do you fill a hollow tree with?
Use spray insulation foam as a tree filler to keep out moisture, children and animals and improve the aesthetics of the tree. Select a product that is water-resistant and designed for large gaps, advises the Centers for Disease Control and Prevention. Follow the package instructions to fill the cavity with the foam.
What kind of tree is hollow?
Naturally hollow trees are very unusual, but do occur in the Neotropical pioneer species of the genus Cecropia, where internodes are either hollow or filled with pith—depending on the species. These species are fast-growing, relatively short-lived gap colonizers in tropical forests.
