Baumgrenze, thanks very much for the links.
Axier, I found that the success rate of my more recent grafts has not been quite as good. A Panachee graft from last year hung on without doing much until this spring, when it finally took off. However, the union didn't look very strong. My intent from the start was to air layer it, which I did, and I'll soon remove it--but for some reason the roots don't look as robust as I'd like. One graft never "took" at all, and another is growing slowly. I had a couple of Persimmon failures, although most did great.
On the other hand, two grafts from Cecil's neighbor's Celeste are doing very well and are about ready to air layer. By contrast, three cuttings from the same tree that I rooted directly in the ground at the same time all started okay, but one died and the others are nowhere near as far along as the grafts.
That said, I'll probably stick with the rooted Celeste cuttings because I know the tree I grafted onto has heavy FMV; maybe the cuttings won't get it. (I planted them at the base of a struggling UCD Celeste, which I will remove once either of the new ones is thriving.) In truth, I'm now less enthralled with the whole notion of grafting figs, and will probably stick to air layering or rooting cuttings in the future.
Here are some photos:
