Potential Chestnut Orchard Site Examined

On April 30, Sandy showed Jack and me her land which she hopes will become a chestnut orchard site. We dug a soil sample and it looked dark and rich in organic matter and It was not overly wet after the recent heavy rains. I concluded that the site has good potential for a chestnut planting possibly next spring.

After we viewed the potential chestnut orchard site, Sandy took us to a neat forest which was close to her possible chestnut orchard site. It was dominated by oaks, especially chestnut oak and in the shrub layer we found lots of blooming azalea which is quite rare in Middle TN. The place looked like good chestnut habitat and sure enough, Jack and I soon spotted a couple of American chestnut sprouts. Had we more time, I am confident we would have found more.

I have attached a few photos of Sandy, Jack, and me at the potential orchard site and the nearby forest.

For all you chestnut nerds out there, here's a great read!

From the abstract: Over a century after two introduced pathogens decimated American chestnut populations, breeding programs continue to incorporate resistance from Chinese chestnut to recover self-sustaining populations. Due to complex genetics of chestnut blight resistance, it is challenging to obtain trees with sufficient resistance and competitive growth. We developed high quality reference genomes for Chinese and American chestnut and leveraged large disease phenotype and genotype datasets to develop accurate genomic selection.
