The damage occurred long after the ideal grafting time had passed. I was given some residual scionwood from a friend and was able to replace a couple grafts lost to the hail plus some additional varieties. Most of the grafts took, still not as many as I had started with.
Andy, thanks again for all of the Scionwood!!!
Next year I'm planning to reduce the number of grafts a bit, I will most likely replace only the ones I lost to the hail, we'll see.
