black knot-resistant plums and cherries?
I lost an older prune plum to black knot. There are wild black cherry trees with black knot growing here and there that aren't mine to cut down and I couldn't afford to anyway - you read about the $80 tomato - I would have the $5000 pint of cherries.
So far my young North Star cherry shows no signs of infection. Knock on wood.
I have read that President plum is fairly resistant and that Auburn University introduced Roadside plum which is supposed to be very resistant. Introduced way back in 1984.
Are they worth growing? Any other plums? Newer plums? I am especially interested in giving European-type plums a try, not much interested in prune plums.
How about cherries? Would the bush cherries be resistant or immune?
