apples on saskatoons

apples on saskatoons. in the third year with this group many are flowering. dwarfing, precocious, reasonably graft compatible. note the union in the second last photo, kind good. so can you graft apples like this, does it work - well yah seems like it, they'll be small trees but despite a lack of evidence on the wider internet, it's working. why use wild saskatoon? well, in my case it's all around our property, and in many areas not very productive, yet it's a very cold hardy tree, very drought tolerant, good properties for a rootstock, also very disease resistant. one thing I need to call out, it doesn't heal over like an apple - so I've had the best result using a whip and tongue or even better a z graft, if you use a bark or modified cleft it leaves a section of stump exposed - don't do that for saskatoon it causes die back the tree won't recover from. so this is an example of technique that will change the outcome.
