True confessions: 2013 or so I benchgrafted Virginia Beauty on G 30 rootstock. I then (inadvertently) burned the foliage by spraying insecticidal soap at 95 degrees weather; next year sprayed it with Roundup (had wrong sprayer); and next year smeared Tanglefoot for ants/aphids directly on the trunk bark. In each case I scrambled to limit damage after discovering the error of my ways.
The tree survived these insults in puny, weakened condition: almost no new growth. Two years ago I started topworking Belle de Boskoop, an extremely robust, vigorous grower. Photo below: tree in stunningly good health today, can hardly believe it. Plus Boskoop is one of three best apples I’ve ever eaten right off the tree; highly recommend. I should name this tree Rasputin.
