I’m a complete novice when it comes to gardening, but my family and I dove head first into it this spring. Approximately, two weeks ago we planted the following: 2 Lapin Cherry, 2 Red Haven Peach, 2 varieties of apple. Our soil leans slightly toward clay, so we seem to finally have figured out less watering is better as the dirt stays moist for longer periods of time. Nevertheless, this evening I noticed an odd looking section on the trunk of one of the cherry trees. It almost resembles a holed out area where you can see the inner section of the tree. Based on my research this appears to be bacterial canker. Is anyone willing to offer their opinion? If it is, what is the best course of action? I’ve seen videos online where folks carve out the diseased section.
