Lon,

Do you know if the Cecil Farris walnuts you mentioned would do well in
the Pacific Northwest?

When you say Japanese walnut, do you mean heartnut? They cross with
English walnut, so you shouldn't need a pollinator on that account. As
to needing one otherwise, it varies. Some English walnuts shed pollen at
a different time from when the female flowers are receptive, so you need
a second tree that sheds pollen at the right time. Others shed at the
same time as the female flowers, so they can self-pollinated. Nor do
they necessarily have to take a long time to bear. Cecil Farris in
Michigan bred selections that would start to bear the season after the
nut was planted. Other types might take up to ten years to come into
bearing. Just depends on the genetics of the particular tree.

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?

Thanks!

Mark
