The bigger the better. Have lots to trade, see my trade list.
You caught me a week too late. I gave a buddy in town a full grocery bag of huge bur oak acorns, and I know he already planted them. I sowed however, 10 flats, so if you don't succeed this year, look for me next fall.
pblume, I don't have any bur oak acorns at the moment, but I saw that you listed scarlet oak on your "wants" trade list. Are you still looking for those? Or others?
