How Long Do the Flowers Bloom on a Pumpkin Vine?

Pumpkin plants are monoecious, which means that each plant produces both male and female blooms.Pumpkin vines produce male pumpkin blossoms several days before female pumpkin blossoms, and only female pumpkin blooms produce fruit.The tiny, swollen ovary at the base of the flower begins to grow as soon as the female pumpkin flower is fertilized, which happens after pollen is transfer from male pumpkin blossoms to a female flower by bumblebees and other insects.With both male and female pumpkin blossoms lasting only a few hours each day, conditions need to be ideal for pollination.Cucurbit plants like pumpkins rely on specific insects – bumblebees and squash bees – for pollination, and bad weather can keep these pollinators from venturing out into the open to collect pollen, reducing the chances that these short-lived squash flowers will be pollinated. .
