Grafting

Grafting Resources

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:

Our Director of Science, Jared Westbrook, was interviewed by Ira Flatow, founder and host of Science Friday, for their podcast. The episode is now available: www.sciencefriday.com/segments/restoring-american-chestnut-tree/

On Science Friday, Jared discusses the multiple approaches taken to improve blight resistance in American chestnut trees, TACF’s recurrent genomic selection program as our main engine for restoration, and what successful restoration looks like.

Black History Month provides an important opportunity to honor the past while also recognizing how Black knowledge, leadership, and community continue to shape the present. From histories rooted in land and survival to modern platforms and outdoor spaces where connection and representation matter.

Today we’re highlighting Hattie Carthan, who fought against the impacts of redlining and disinvestment by mobilizing her Bed‑Stuy community to restore its trees and protect a landmark magnolia. Her legacy shows that restoration starts with us, an idea at the heart of our work to revive the American chestnut.

So trees DO grow in Brooklyn again?!

Our air pruning bed was constructed in early 2025 and has since been growing hybrid chestnuts that play an important role in our grafting work. Air pruning beds allow us to grow strong, well-branched root systems and make it easy to access high-quality rootstock for grafting. MRF staff are currently grafting using the root stock from trees that were grown in this air pruning bed, so stay tuned to learn more about it next week!

Our research just dropped in Science, and the media wrapped it in love.

Here’s your Science Release Wrapped: the most notable mentions, the biggest themes, and the breakout moments that made RGS the star of the week.

Thanks for all the love.
