So last weekend I chopped down a tree, not sure what it is. Elm, scrub oak maybe. I just don't know. Anyways, I chopped the tree down and cut it into one 6 foot log and one 5 foot log. I smeared Elmers glue on the ends. Well today I went out to my shop and saw there is mold growing on the ends of the logs! Is this a problem!? What should I do?!
