So I’m buying a new house and there are two large mulberry trees in the front yard. One looks awesome, the other looks like it only has 30% of the leaves it should. Slightly yellow maybe. I don’t see any herbicide injury, that’s a normal issue here. It was a wet spring, but the ground is dry and cracked now. Tree is 2.5’ diameter or better. Healthy tree next to it is bigger. They are too close for my liking for their size. I have a chem liscense and can get anything needed. Will try anything to save it.
