My single Chinese Chestnut sets nuts?
I'm thinking about collecting some of the nuts from my Chinese Chestnut tree for seed exchange, so I've been reading up a bit recently on them.
Only reading up on them I'm confused. Most of what is written out there states one needs two trees for pollination to ensure nuts, but my single tree has set nuts for the last two years we have been living here! And a lot of nuts too. There are zero other chestnuts anywhere remotely nearby as far as I can tell.
So, a couple questions if anyone can help me out.
Will the nuts produced from this tree be viable for seed exchange?
Are these nuts any good? For human consumption that is- we haven't tried them yet, but all the squirrels eat the dickens out of them.
Is it possible this old tree comes from grafted root stock of 2 trees together, thus making nut making possible?
Thanks for any advice anyone can provide.
