Yes, that' s an interesting report from Ilya and very informative.
But winterhardiness is often very different due to multiple
influences as rootstock, plant age, dormancy,location,....
In the first pictures you see left Bloomsweet with no damage and right
Slava Micurina with some leave damage of small twigs, otherwise
Slava is also O.K.
Good example for influence of only different locations and Rootstock of the same variety in
picture 2 and 3.
Picture 2 Dunstan with late morning sun - very healthy. Rootstock Flying Dragon
Picture3 Dunstan with early morning sun - some spolled twigs. Rootstock Poncirus
