Hello. The house I bought has a fairly established Rhamnus cathartica tree in the back yard. This spring, I noticed it looking absolutely haggard. Upon closer inspection, it appears to be struggling. I think possibly with anthracnose? Brown spots throughout the canopy, even on the new growth. Is anyone able to confirm from the photos? I will likely have it removed as it is known to be susceptible to anthracnose and is invasive, but knowledge is power and I would love to avoid infecting the replacement tree in the future. Followup question: could you guys recommend a small-medium shade tree that is not susceptible to whatever this tree is afflicted by? Thanks! Emily
