I have 2 CHO Dunstans and 1 Chinese from Edward Fort Nurs in an open field. Been bearing now for several years. '21 we had poor pollination and we still weighed / sold 55 lbs. The Dunstan nuts are much bigger, and always drop 2 weeks later than the EFN. I don't care about the size, just saying that's what it is. I have planted a few other Chinese in the past few years and this spring put in 3 alleged Americans. That puts me at 10 total. These are all at my house. Future owners can have fun collecting/selling them, or just let them lie. I've strategized a variety of fruit/nut drop times to feed potential farm animals, same as my strategy in the woods. But we rarely have deer at the house, dependent on cover left on surrounding farmland. I got started with CHO Dunstans because I couldn't find any local sellers of wildlife trees, and at that point had never tried mail order. The WalMart distribution got me involved. Initially they would sell out in a day, and I was always calling to check and even making extra trips to check in person. First year I missed it, next year got a couple, next year missed it. Nowadays they don't sell as fast. One store carried inventory all summer. If you're only planting a few, and you're already an old guy, CHO trees from Wal-Mart are a good choice. My CHO trees bear after 3 yrs, and bear well at 5. I think chestnut orchards are great for harvest or wildlife.
