Wow, beautiful old tree. I planted two grafted cornus mas bare root from Fedco last year, on the takeaway from Lee Reich’s books that it makes pretty good fruit, is problem free, and decorative. They didn’t do much growing last year, and had some kind of black spots on the leaves (anthracnose?). This year they are doing better and put on some growth, but still don’t look very robust. Hopefully next year they will pick up steam. The soil they are in is not great and pretty dense, but I’ve put compost on top the last two years, water them sometimes, and have sprayed with fish/kelp/EM-1 that I used a few times on my apple trees this year.
I’m kind of worried though, because I discovered one or two cornelian cherry behind the public library in Lexington, which I kept an eye on last season since I pass close by on bike commuting to work. They did not put on much fruit, and what was there went from intensely tannic and sour to vaguely rotten tasting right before falling off. Hopefully the varieties I planted are better for fruit!
