Last year, I ordered the same variety, "Olympian", from Wellspring Gardens. I also got some shrimpy looking trees. Within a few months, growing in full sun, the trees took off and grew so tall that they had to be nipped back constantly. A few of the trees even set a few main-crop figs...which were also nipped off. I'm sure that I will get some figs off my T-C "Olympian" and "Black Mission" trees in the coming, fig season.
In Zone 9B/California, I'm sure your small little trees will do just fine once they become acclimated to your growing conditions. Good luck.
