Unpollinated Tomato Flowers

[nightshade]

Anybody else having a problem with their tomato plants? mine have loads of flowers but very few tomatoes (two ripe ones in six plants!)
They are new seeds, one lot standard and the others plum tomatoes, in baskets, the plants look fine and health, and have been grown in the same
way as we have sucessfully grown them for years. Any ideas?
Some are down under the open back porch and some at the top of the garden, in the greenhouse and outside

Are the flowers just dropping off? Maybe lack of insects or watering. You'll have to resort to the old rabbit tail or cotton wool and pollinate them yourself. Have you seen insects on them?

Perhaps you should give the stems a shake on passing .I have done this and get some developing later.

Artdemole is right.
When I did my horticultural apprenticeship, (back in the early 60's), the old head-gardener insisted that if you walked past tomato plants, you must tap the supporting sticks as you went in order to achieve maximum pollination.

Tomato's thrive in a dry atmosphere, watering must be very regular and never over-done especially when fruit is ripening.
