On the fungicide issue, last summer I had [briefly] a wonderful black cherry that I potted up, from some aged nursery stock. Cherry bark will eventually get a crusty look to it, almost as if covered by lichen, and mine was just that. It did, however, have a somewhat persistent case of black spot, which I attempted to treat. I use the past tense because I learned the hard way that certain fungicides become phytotoxic when applied at temperatures above 80 degrees Fahrenheit. My grandfather used to say that, "yes, the school of experience is the best teacher, but sometimes the tuition can be expensive."
