Apple on Saskatoon graft

Apple on Saskatoon graft. In late summer well past grafting season I grafted onto about a dozen small trees, happy to see most are leafing out. Saskatoon is in the Rosacea family with apples and pears and has been used experimentally as a dwarfing rootstock for them. There’s some conventional wisdom that pears will work, but few reports about Malus. This is an excellent result and will be followed up on. #grafting
