I've got a "nut" question that I'm guessing a fruit expert can answer....
Having limited acreage, I tend to stick with native species (black walnut,
butternut), but am interested in planting Japanese and English walnut. My
question is will I need to plant two of each of these, or are they
self-fertile and/or will pollinate with the native trees I've planted? In
addition, I've planted some seedlings of these (Japanese and English), but
have now come across grafted varieties. I'm guessing if I want to see nuts
in my lifetime, I should pull the seedlings and replace with grafted?
