I started lemon cucumber seeds on May 1st. The seed packet warned that these cucumbers are late to mature. They weren't kidding. Four months later, the vines are finally flowering. As a point of comparison, I started Marketmore 76 and Hybrid Soarer seeds on July 12th, and these started flowering at the same time. I went out to hand-pollinate the cucumbers yesterday, and there were several big fat bumble bees already at work gathering pollen. It was fun to see those huge bees forcing their way into the tiny cucumber flowers. I decided to leave them to their work, and hope the females were successfully pollinated. I'll know in a few days.
