Geraldine, each pumpkin plant should produce both male and female flowers. The earliest flowers that emerge will be male and all up there will be more of them produced in total than female. You may or may not have to encourage pollination. If you have bees hanging around they'll do it for you. Consider making your vegie patch more enticing to bees by companion planting some bright flowers (like calendula, nasturtiums, french marigolds, sunflowers, etc) to attract them. Anyway, the way to tell the difference between male and female flowers (in case you didn't already know) is that female flowers will generally have a bulbous base near the stalk, below the flower. Also, since they take up a lot of room, have you considered training the pumpkin vine along a fence or up the side of a garden shed? A workmate of mine had them fruiting up on his shed roof last summer.

Hello Pumpkin Growers I am attempting to grow pumpkin for the first time. Do I need to grow at least 2 plants? I am not sure if the plants have both male and female flowers, or are single sex? Any tips appreciated; I do realise I will have to "encourage" pollination.

Liss, Pumpkins are not really heavy feeders in my experience also to seem to require little water. They really like sulphate of potash, that can be either burnt ashes or a comercial product. A few watering every 3 or four days will keep them thriving. A point to remember is that when the fruit begins to develop don't increase the water or the fruit may split. Hope this helps. Warren

Are pumpkins heavy feeders? What do they like? In the soil I mean.

Brendan, I have seen a pumpkin vine that took over a paling fence Approx 15mts. But all the fruit grew on the neighbours side. Lucky we got to share

brendan - have not tried the clothes line, but have tried a pergola of sorts. Grew vine up on to shed and worked a treat, higher, more sunlight.

I have been growing Queensland Blues & Jap Pumpkins here in Sydneys West for a while and would like to know the following : Male flowers are plentiful usually at the start of the vine & female flowers are not as many but as the vine lengthens more females appear, so how far do you let the vine grow. If cut does the right ratio of flowers continue shoot or that stops everything, what you have is all you get and do you plug the cut end to prevent disease getting into the vine (read that on the net) Also everyone says when the vine withers pick your crop, mine was going great and green but I picked them (stem still green & firm) as I felt they were large enough but several had started to rot inside, we saved them luckey as another couple of weeks would have lost the lot. So how do you know when to pick. heard about tapping it sound hollow its ripe, pick a piece of skin with fingernail the skin can give you an idea. Noticed in the fruit shop many pumpkins have fingernail pieces dug out ??? somebody know something !!!!! As the pumpkin is pollinated & starts to grow do you sit it on a tile or similar keeping it off the ground ( for air & warmth circulation) sometimes when left on the ground the under side looks soft and worms and bugs seem to love that position.
