@oscar I hadn’t even though of chip bud grafting! That’s not a bad idea, it’d certainly let me pick my preferred position on the rootstock, and I’ve heard that they, while fiddly, have a great success rate.
I’ve also heard that doing notching (making a cambium layer cut) just above the dormant bud will get it to take off (something about disabling the hormone flow back down, that causes apical dominance).
I’ll definitely keep this approach in mind for when the rootstocks arrive!
@BlueBerry This was my initial thoughts exactly! You don’t see any issues with structural integrity doing it this way? i.e. should I take extra care to trellis/stake it than usual because of the nature of the grafts?
