Clark, this may be a silly question, but could Callery pears be used as a disease resistant semi-dwarf rootstock for apples?
This post seems to infer it has been done before with Bartlett/seedlings on a large scale. Apples grafted onto pear rootstock for cider in old days
If so is there a good reason why this practice has ceased and apple rootstocks are more prevalent? I could see a happy disease free Callery being a superior option for both apples and pears in most circumstances.
An additional question - has anyone tried rooting cuttings from Callery?
