Here the tree can absorb valuable nutrients from decomposing dead plant matter. Roots may grow from the trunk down into its hollow middle, in old trees, to absorb the minerals released as fungi and, to a lesser extent, bacteria rot away the dead wood.
What does it mean if a tree 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.
What causes a tree trunk to be hollow?
Why do trunks become hollow? A hollowing trunk is a natural process and it's not necessarily a sign of an ailing tree. The centre of the tree is deadwood which is slowly decayed by fungi. The fungi is perfectly happy in the deadwood and will rarely touch the living sapwood.
Do trees have deep roots?
A tree's root system is typically fairly shallow (frequently no deeper than 2 m), but is widespreading, with the majority of roots found in the upper 60cm of soil.

What type of trees are hollow?

Can you fill 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 can a hollow tree survive?
Bacteria and fungi lose no time moving in and beginning the decaying process, which can result in a hollow tree. Because the sapwood, and therefore the transport system, is still intact, the tree lives, despite the loss of its inner heartwood.
How do you treat a hole in a tree trunk?
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.
