Back to selecting a female . . . . plant. I assume you know the difference between a male and female pumpkin. If not, the female has the fruit under the flower and the male is long slender stem with a flower on top. Now we have discussed the difference, find a female plant with the correct angle on the vine and with five plus segments. If the vine versus the female plant is acute, the stem will be more likely to be damage as the pumpkin grows.
Segments are the cavities which contain the seeds.
When you look inside the flower, you will see the segments. The female flower is characterized by the multi-segment stigma located in the interior of the flower. Pollinating the blossoms can be done two ways. The primary method is described in Hand-Polli nating Pumpkin Plants. Go back and read it or this will not make any sense.
