Just spent abotu an hour cracking butternuts, i got about 1-2 cups worth, i'm thinking chocolate chip butternut cookies. i'm actually making room for this years "cash crop". this year our big tree 18"-24" produced bushels of huge butternuts, our small trees 6"-12" produced hundreds of nuts, but most of all them are about half the size of a regular nut. i've noticed this on black walnuts too. does any one know what makes a nut tree grow/ produce so well in a given year. such as in the weather?
