I've just been mooching about my cherries, plums, gages and damsons and it looks like an appalling yield this year. All the trees look hale and hearty but next to no fruit. There were lots of cherries forming but the ground around them is now covered by under developed, unripe cherries that have fallen off and I think this is due to lack of pollination, certainly the couple I broke open this am don't have stones in them.
This makes me think that maybe there was a shortage of pollination insects doing their thing during the wet and windy Spring we had here.
Strawberries, raspberries, black currants, blue berries and gooseberries are great and apples look to be doing OK so far but nothing with a stone. As far as I can remember there were plenty of flowers on the trees, l do think I'd have noticed an absence of flower anyway.
I'd be interested to hear whether anyone else has a similar picture this year.
