What we grow and harvest at Chestnut Ridge of Pike County are DUNSTAN CHESTNUTS (Castanea dentata X mollissima).


There has not been a single reported instance of Dunstan Chestnuts dying of blight infection in over 30 years. This includes research and breeding programs as well as the many other locations where the Dunstan Chestnuts have been grown throughout the nation.

Dunstan Chestnuts have been tested for resistance by inoculation with blight. No significant canker formation was observed for 4 years. Limited growth of the blight cankers was seen on only a few trees and, in most cases, the inoculation wound healed completely.

Reports from growers at thousands of locations around the U.S., from New England to Michigan, south to Florida and Texas and the Pacific Coast have shown that the Dunstan Chestnuts have excellent survival, growth and nut production in a variety of climates, from Zones 5-9.

Many chestnut trees sold in the U.S. are not blight resistant, such as seedling American chestnuts, or European x Japanese hybrids (including Collosal). Blight resistance is extremely important, even in areas that currently do not have blight. Accidental outbreak can destroy susceptible trees. In blighted areas (the entire eastern U.S.), only blight-resistant trees will produce.

Dunstan Chestnuts produce heavy yearly crops of very large and sweet-tasting nuts. The nuts average 15-35 nuts/lb, as compared to Chinese nuts (35-100/lb) and American nuts (75-150/lb). They are much better tasting than imported European nuts and are never bland or bitter. The nuts peel easily, unlike imports, that have clinging and ingrown pellicles (seed coats). The nuts ripen in September and October and most fall free from the burrs for easy harvesting. Dunstan Chestnuts can produce nuts in only 3-5 years after planting.


The blight-resistant Dunstan Chestnuts make possible the re-establishment of chestnut trees to the forests and creation of a chestnut orchard industry in North America.
