There is evidence of slight rot where the tom is attached to the plant
which has caused it to fall off.
I cannot find any reference to this problem anywhere.
Any views please

Peter this happened to us once last year. Ours are grown in the
greenhouse in huge pots, We think it is caused by underwatering and
then overwatering. We deduced this by going away overnight during a
hot spell, when we returned the leaves were a bit limp so I gave them
copious amounts of water. They started to ripen and then fell off,
not all just some, exactly with the same black bit of rot at the
stalk. The ones that did not fall off were outside ones.

This year I haven't had a red tomato yet although the crop is big and
healthy, usually I have made pickle by now.

Thank you Judith, I am not aware I have neglected watering but on the
other hand I may have done due to the change in weather from am to pm.
This year one of my plants must have at least 50 mature tomatoes on ,
I have to tie them up. I have already had about 3 lbs off, delicious.
Peter.
