Thanks! Esshup, similar instructions for the hybrid chestnut in the link that you shared? your link doesn't seem to be of the dunstan type.
Those hybrids aren't a Dunstan. They are a cross between American Chestnut and Chinese Chestnut, They do well in zone 4-9 and I can attest that they are fast growers, growing out of the tree tube that they furnish with them in 2 years. Their tree tubes are different than most, as they condense water vapor at night to help water the trees. I put this up here because they are a very fast growing chestnut tree, and should start producing nuts in 3-5 years post planting.
