What do I do for my magnolia tree that is giving off a sticky substance?

Answer by  SallyJ (1010)

You have a magnolia pest called the magnolia scale insect. This can damage your tree. Use a ground-based insecticide to kill the bugs.

It is actually a common thing for your magnolia tree to give off a sticky substance. It is a defensive thing in order to catch bugs etc. You really can not remove the sticky substance off the tree as you can risk causing the tree further damage and harm which can kill the tree.
