I transplanted Diva Cucumber vines to our garden in mid April this year. The plants are growing great, and there are lots of small cucumbers on each vine. So far all of them are just falling off. I'm under the impression that Diva does not require bees for pollination, or so the seed package said.

We have had a cool spring here for a change. When should I see cucumbers filling out? Do I need to plant a different type of cucumber to serve as a pollinator?

Thanks for any help that can be offered.
