So this question is basically centered around Pastiliere and it dropping fruit but growing out of it eventually. I wonder if it and other varieties like Celeste drop their figs because propagation  has triggered them to show juvenile characteristics ie. growth at the expense of fruit.Would grafting one off these varieties onto an established rootstock change it's fruiting habit as it does for seedlings?

If grafting was only 60% effective I think more people would talk about it and less people would do it. Plants simply do not reproduce or change in that way. Making new hybrids would be very easy if that were the case. I do think that using a rootstock with less juvenile tendency might help though.

Pastiliere is tough to spell, Hirta would be easier.

I hope to see for myself if My UcDavis Pastiliere will be like a normal fig tree holding its figs.
In 2009 it was a mere baby.   Im having patience with my pastiliere as the fig taste is up to my personal standard and this is reason why i will give it some years to see what happens with this type of plant.

I came very close to discarding it or planting it in ground unprotected to punish it but i held back in doing so.
I now let it get more seasons in my yard to see actually whats what.

There are lots more people trying or re-trying Pastiliere based on your few  figs last season Martin (they snatched up those cuttings I wanted on eBay anyway). I was hoping to figure out some way to get more of those figs to hold on. I do not have any extra nodes of Pastiliere to try a graft this year but I think I will try Celeste to test my theory (and get grafting practice). Please consider the idea of grafting Pastiliere in your yard for posterities sake, and of course for the figs.
