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?


Thanks,
