Nut-grafting!
January and February are the best times to cut scions from American chestnut trees and graft them onto American chestnut nuts. If they grow, you will have a clone of your scion wood tree that can be planted in a new location. Carl Mayfield, shown above, is an expert on this method of propagation. He graciously allowed us to take video at his nut-grafting clinic last winter, and he wrote out detailed instructions for every step of preparation and nurture, which can be found here:

Great video, keep them coming.
Thanks. I have one from OIKOS that was advertised as 95% American. Here's the trunk -- alittle blight on the lowest branch at left, but that's been yrs ago and has healed over. It's been putting out male pollen racemes, but they don't open (become fuzzy) -- don't know why.

Transgenic American Chestnuts are still a much better option. The product of this method will always be a hybrid and that should not be the goal.
