This I think happened to me last year. My pluots all bloomed, but only Flavor King set fruit. FK seems to be the hardiest I have. Worth trying for sure.
Good info thanks! I’m going to keep that info for my records.
Is it winter, or spring that is causing the problems? If it’s winter try Wilt Stop. Try to apply twice.
I have not confirmed this product works but so far it really does seem to work. It’s worth trying.
I got down to -16 two winters ago, and I had peaches. Not all the buds survived, although I did get about 25 peaches on a 3rd leaf tree. Well on 2 trees, Another tree only had 7 peaches. All my western blackberries survived. These are like zone 7 plants in zone 5b, and they made it. And again this year. I lost about 3 canes out of 30. Bosenberry, and Marionberry made it.
One person at least tried it last year.
