Male blossoms are longer and thinner, with the appearance of trumpets. The males have a stamen on the inside of the blossom. Female blossoms, on the other hand, are wider and shorter, with a more open appearance and no stamens in them.

Use a clean paintbrush to carefully collect the pollen from the male blossoms. Then, use the brush to gently touch the pollen to the base of the female blossom. After pollinating, make sure your pumpkin has enough light and that you water it regularly.
