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?
