I obtained these disease resistant pears (among others) to graft from ars grin What scions will you graft in 2017?. Hard to believe I would then turn around and grow abate fetel or forrell. I have a practical side when it comes to growing pears but I’ve had some sensitive varities e.g. Clapps favorite killed to the ground with fireblight. I try to grow my sensitive pears in an isolated location.
