If you look at my photo bucket on here you can see where I had my start. I'm currently at 30-40 trays of 4 varieties of chestnuts. each tray has maybe 18 or 36 spots, I can't remember. So, probably an over kill but I am raising them in rootmaker trays and they are doing very well. I know some like the American Chestnut and I could be wrong with not going with a more pure variety like that. My thinking was (and I may be wrong)..... get 3-4 varieties that are mainly disease resistant (15/16th's american is one example) and at least some of them should do well. Kinda the shotgun approach. Same with deer preference, some they could like better than others. Though, from my research, I think something like a Dunstan may be over-hyped and marketed and many folks have told me their areas with different kinds - the deer don't care which of the chestnuts. I am including some Dunstan's too and hoping a buddy who frequents this site will send me some seeds if he has a good year! So, right or wrong, I bought several varieties, a few lbs each and growing them in rootmakers, putting in 1-3 gallon rootmaker pots this season and then planting the following with tree tubes. Babying hundreds to get as many to maturity as I can. Good luck and if you need a nut source to purchase from, lemme know. Don't forget your apples, pears, persimmon and dwarf chinkapin trees either!
