A neighbour has a fig tree laden with figs which which aren't ripening. He

ripening.

Anyone have any ideas on this please?

He's grown it as recommended here.

"Figs can produce three crops simultaneously and invariably have two
on the go at any one time. At this time of year there will be the
large ripening figs, half-sized ones and, if you look closely, tiny
pea-sized - even pin-head - fruit tucked into a joint between stem and
leaf. These tiny ones are next year's harvest. The in-between ones -
essentially any that do not ripen by the middle of October - will
never ripen in northern Europe. In a mild winter they start into
further growth, but the skins are tough, so they split and fall off,
which weakens the plant and delays the growth of the very small ones,
meaning that they often fail to ripen too. So the solution is to wait
until November and then ruthlessly remove every single fig bigger than
a pea. Resist the temptation to spare some that are hazelnut sized and
put your trust in the minute figlets - these will grow and swell
rapidly the following summer."

I don't recall ever finding wild ripe figs up here in North Yorkshire
and there are plenty of mature fig trees with big unripe ones on.

We just don't get enough sun. You might stand a chance some years in the
London heat bubble or the extreme south but I reckon it is borderline. I
do have a Brown turkey fig but it never has useful fruit. Its
predecessor was killed in the same winter that did for my tree fern.
