We have what looks like green mold all over the trunks of our two maples that are close to the house. It goes away when it gets really cold but comes back when it starts to warm up a little. Is it mold? Can we get rid of it? We do not remember it being so bad as it is this year.

Greetings Joan:
Please email me several high-resolution images of this green mold-like substance growing on your maple trees as I need more detailed information in order to provide you with some recommendations.
