I'd chip bud them in July...

thx. will give that a try.

how big is the growth caliper wise? If you have nice branching, I would select the ones you want now and start training them, and then graft onto them next year if they're reasonably sized. Chip bud is ok, but you could whip and tongue a nice sized branch to them and be way ahead of the game next year. I had this years grafts flower and fruit on a few.

I would do the chip bud, then any failures still have the top on to be grafted in late winter/spring.

They graft quite easily, I find using grafting grease over the tape and on the cut end of the scion works a bit better.

I also found some stone fruit varieties that were susceptible to bacterial disease benefited from spraying the scion and the rootstock with copper oxy chloride before grafting.
Especially apricots
