Update: As I speculated in another old thread, Rosseyanka’s issues with anthracnose seem to stem in large part from weakening by spring freeze damage. Of my several persimmons, it is the most susceptible to late freezes; even Nikita’s Gift will put on decent growth after cold damage in spring (and without severe fungal issues)—but Rosseyanka struggles with it. Frozen out nearly yearly, Rosseyanka has an increasingly difficult time recovering from the damage, which includes dieback of small wood and even dead spots in main scaffolds—and its recovery is complicated by the opportunistic and progressively more severe anthracnose infection which follows each such event. The tree grew hardly at all last season, and this season, after more spring dieback, it has lost half of what little fungus-blackened foliage it was able to squeeze out. Shoot infections are extensive and severe. Even a delayed dormant spray of copper didn’t help.
Since planting it, I think I’ve had one spring when it wasn’t frost damaged, and that year it grew okay and had mild, mostly cosmetic anthracnose. It has never bloomed.
Rosseyanka seems a waste of time and space here—and possibly in all climates with iffy springs. It is slated for topworking.
