A time of Honey, Horses Hoofs and Oysters

Updated: Sep 24, 2019

Autumn is the time of year that some fungi such as Honey fungus, Horses Hoof and Oyster fungus produce their distinctive toadstool or bracket type fruiting bodies.

These are the above ground and visible parts of the fungi but it is what is not visible to the naked eye that causes the problems for tree owners. The underground fungal strands of Honey fungus spread through the soil infecting a large range of trees and shrubs. This infection decays a trees root system which can result in its collapse and eventual death.

Hoof and Oyster fungi produce bracket type fruiting bodies which appear on the trees main stem and larger branches. As the fungus degrades and digests the wood it will eventually cause branch and stem failure.

There are a vast number of fungi that grow on, within and around trees with the majority being completely harmless to trees. Some known as mycorrhiza are beneficial and help trees grow by releasing additional nutrients in the soil.

However there are the 'bad guys' which are destructive and can compromise the safety and health of a tree by weakening the trees structure and stability.
