5 year old buck +
I have a bunch of seedling crabs planted from CSF that will be going on 4th and 5th leaf next year that I would like to top work over to some more desirable varieties. I also have over 100 grafted trees about the same age, so no shortage of scion wood. My biggest problem is living >1000 miles away from my farm. I am wondering if there is a window where I could harvest scion and cleft graft in the same week. Alternatively, I could harvest scion and store it in my basement until ideal cleft grafting time, but I think the temperatures may get below freezing. Do freezing temps kill dormant scion wood? I am in Southern MI, zone 5. Thanks for any insight.
