Linden Tree Has White Foam Slime

Question From: Morrisville, Pennsylvania, United States
Q: We have white foam slime on our linden. Never saw this before. How do we treat this?

A: Your tree has a disease called slime flux. Hose it off with a stiff stream of water ever few day. I don't know of a cure. You can get an onsite inspection from a certified arborist. Go to and enter your zip code in the search box. Best Nancy
