Why Do Eucalyptus Trees Shed Bark? ... Shedding eucalyptus tree bark may help keep the tree healthy. As the tree sheds its bark, it also sheds any mosses, lichens, fungi and parasites that may live on the bark. Some peeling bark can perform photosynthesis, contributing to the rapid growth and overall health of the tree.

Why does eucalyptus bark fall off?
