It is fairly easy. A male flower has a single central stem in the middle of the flower. Like a small pencil. It has a sort of yellow pollen on it. A female flower has a circular thing in the middle of the flower. If you want to hand fertilise you just break off the male stem and stick it in the female thing and rub the pollen off. It is the same procedure as for all life I suppose.

I see we should avoid growing pumpkins and potatoes together. I have 2 vegie gardens, they are about 8 meters apart. I grew potatoes(sebago?), tomatoes (gross Lizze), and for the first time capsicum and lettuce in the big one, and jap pumkins in the smaller one last year. Lettuce were great until a hail storm hit, tomatoes, potatoes and capsicum all went well. But the pumkin in a virgin patch went ok, although some fruit did not develop. I had about 8 vines, and at one point there were 25 fruit starting to grow. Some of the flowers did not even open. Others got bulb end rot. I got about 10 good pumkins off the patch, which I think is ok considering it is smaller than recommended at 2 by 3.8 meters, and it was the first time anything had been grown in the soil. Did I have a lesser success with my pumkins because the potatoes were close by? I did have to hand pollinate a bit. What are the main reasons for not growing spuds and pumkins together?
