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.

Japanese Pumpkins have really long runners (Vines) The male flowers always come first, then the females follow in a couple of weeks then you may have to hand pollinate them if there are not enough bees or insects. it is easy just pick a male flower and brush the pollen gently on the stigma of the female flower early in the morning, you can recognize the female flower because it has the small pumpkin under the flower. It is often suggested to cut the main long runner when about 10 feet long (3m) But here in the Lockyer valley the farmers plant acres of them & get tons of pumpkins, I am sure they don't go to that trouble, they just let them grow. A fertilizer PK of 6.6,6 is ideal as to much Phos. will grow all leaves and little or no pumpkins when the female flower isn't fertilized it will go black/brown and fall off. also if stung by fruit fly will do the same only if you break it open it will be full of fruit fly larvae. How ever when you have a pumpkin setting , you can grow it larger if you cut the vine runner off. can help protect it from fruit fly and birds by covering with straw or a larger pot with a bit of gauze in the bottom and place fruit fly traps. hope this helps. sgallan07
