I love chestnuts to eat. They grow easily from seed. Dunstan Chestnuts have been bred for resistance as well. I ordered nuts from Ebay, stratified and planted them. In the mountains of Arkansas when I lived there they grew so quickly I was eating nuts from them in 3 years. Here in N. Central LA with exceedingly sandy soil it takes longer to get them established, but I had quite a crop last year. The North American Fruit Exchange (NAFEX) had a chestnut group and I used to exchange nuts with growers all over, Michigan too as I recall and learned a lot. Chinese chestnuts themselves taste great too and the trees are not too large. You must have acidic soil though.
