I bought a vigorous butternut/white walnut seedling today.  I just read up on the disease susceptibility in white walnut.  There is a 300+ historic white walnut that near me.  It looks in good shape, although has a large cavity in it's trunk at the base, but still doing well.  Does this mean that this is a tree of unusual disease-resistance?

Should I graft a disease-resistant scion/cultivar unto it?

Are there disease-resistant clones?
