lack of fruit

can anyone suggest an answer to my fig tree problems- one tree had lots of fuit earlier this year but they all failed to ripen just went yellow and dropped of over aperiod of some weeks.
The other tree was very slow to develop fuit and I doubt that they will have time to ripen now?

Have a look here warthog, it might help.
Largeish overwintered fruits drop off in spring, the only ones that grow into good fruit are the tiny overwintered fruits. Like wise the early formed fruit of the current season, dont ripen.

 

Thanks Pete, I will try and look out and protect them this winter-will let you know!
