Gary discusses tree care with our garden guy, Scott Beuerlein.   A listener asks about a tree that's split in half, and Gary shares his expertise on whether it's salvageable. He explains that a split in the bark might not be a major issue, but a split down through the wood is a big problem. Gary also shares a personal anecdote about a silver maple tree that was hit by a car and shares his experience with a London plane tree that had a similar issue. They discuss the importance of consulting an arborist for a professional opinion.
