Tony,
You are right. My main goal was to preserve all these precious Portuguese varieties (thanks, Francisco) that are disappearing and grafting has proved invaluable for that objective, as some of them are not the easiest to root and i might have lost them, otherwise.
Francisco,
Negronne (Whip and Tongue graft) has produced figs 7 months after being grafted and they were very good - Here's a few photos
Sbayi, grafted with the same technique, also had figs developing - Photos - but they didn't mature before the cold and the rains arrived (they started to develop too late, due to being grafted in March).
Of the 4 varieties i grafted in 2017, only 1 - Grise de S' Jean - is showing a couple of figs (it was a very small branch that i grafted and has all the competition of the others, but it's developing well).
It was the only variety (of the 4 i grafted in 2017) where i used whip and tongue and this technique tends to produce a stronger union and the development is usually faster, sometimes with figs in the same year, if the root stock is mature enough, so i prefer it, whenever possible.
The only drawback is that it uses at least half a cutting, usually 3 buds. That's 1 graft versus 3 possible one's with chip-budding so, if i don't have enough cuttings, i tend to use chip-budding which, usually, tends to develop a bit slower and rarely produces figs in the same year - there are exceptions, like the Strawberry Verte i posted about in another thread.
