…don’t think you are out of the woods. I tried 3 scion grafts to rootstocks, and thought all 3 took, because there were small leaves showing. 2 of the 3 seem to have paused growing a while back, while one has done very well. The 2 aren’t dead but haven’t done much in a couple of weeks, and I have my doubts.
I’m afraid my D’arcy Spice might be a goner because both leaf nodules produced small leaves but the damn slugs ate them to nubs. I can’t believe how much they liked this particular variety, leaving other alone.
