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:

Chestnuts look so beautiful during pollination season, their catkins (the yellow fuzzy blossoms) are often described as fireworks. 🌰 🎇

Wow. Way more explosive looking than the European chestnuts. Beekeepers should be all over that. It’s the most distinct honey I’ve ever had.  As for the aroma… Well… Enough said.
I have tended those trees. MD TACF, join us!
Love the scent!
Watch this quick video to learn how we conduct controlled pollinations for our breeding program.

❤️ The original farmstead my property used to be a part of, grew chestnut trees and Hickory trees. The last two American Chestnut trees died about 6 years ago, they were right on the shoreline of a lake and unfortunately all their nuts fell in the water. They died cause they were both girdled by a beaver that had taken up residence on the lake. I would've done something to protect the two trees but unfortunately were not part of my property and all I could do was watch in horror. I wouldn't dare mess with trees that don't belong to me. I would however love to add some if it's possible to purchase American Chestnut back to our property, our parcel had the Shagbark Hickory trees on it.
Big tree - Asian chestnut ?
Did you know that Allegheny chinquapins can get chestnut blight?

Would it get a lot bigger if it didn't get the blight? If so, how much?
A wild American chestnut is always a sight to see, especially one with a healed canker.
Have you found any wild American chestnuts?

Quite a few around us in CT, but none that big. I assume what we are seeing are stump sprouts.
God, I hope it has developed genetic resistance and passes that on. I want to live in a world full of American Chestnuts and Elms again
At my art residency in WV there was an American chestnut tree in their yard! I cried! I collected some of the seed pods
Every season tells a story… 🌰
Maybe it’s a chipmunk on the run, a chestnut sprouting new life, or snow dusting winter leaves. However you see it, we want you to capture it. The 2026 American Chestnut Photo Contest is open!
