Hole In My Magnolia Tree Trunk

Question

My magnolia tree has a large hole in the trunk at the soil line (see picture). The tree has not grown in many years but it is still alive with lots of green leaves and some flowers in season. What can (or should) I do to treat the hole?

Answer 1

This is a very old injury. It looks like it stays in saturated soils, which will cause this. From here, it is best to let the tree live the rest of its life out.

In the future, it is best to find a spot that does have a chance to dry out some. Down to an inch or two, very thoroughly, will be appropriate for most Magnolia trees.
