Sounds like the fruits aren't pollinating properly. when you get both a female and male flower open at the same time, early morning is usually best. Pick the male flower and peel back the petals to reveal the stamen with the pollen on it. find the open female flower (with the baby pumpkin at the base of the flower) and gently rub the male stamen against the female stigma inside the flower. It's like artificial insemination. The fruit should set and grow after the female flower closes and falls off the pumpkin fruit after a few days.

It depends where you are- Pumkins ned a warm, long growing season- 3-4 months. In melbourne thats late spring- end of summer, up further north you need to be mindful of humidity.

Hot weather can be a bit shocking for plant if you've had a bit of a heat wave. I would also suspect under nutrition. They are extremely heavy eaters- early on, they use heaps of nitrogen used for rampant leafy growth, but then need lots of K for flowering after that ( as well as a lot of other nutrients, inc N). Try giving a top dressing of manure, and liquid feeds of Seasol powerfeed. It's got a nice NPK ratio for fruit and flowering. I think in Perth it's not too late.

Hi Phil ..i'm in Mandurah and planted 3 butternuts in Oct and they have gone mad- now about 40 feet long.Lots of flowers and fruit growing but i thought that they would be larger by now.On hot days i water twice as they seem to suffer badly.I've asked a question if i can cur off the end of the runners to max fruit and stop it just growing nad growing.Mine are in sun about 4 hours a day..regards bruce

Yes, i think pinching the tips is one way to try to concentrate metabolic energy. With the water thing- absolutely. In Melbourne here, summer is shorter but can be brutal (I've lived in Perth too). Ours grew in a wicking bed and it was the best thing for it. 45 deg days, not one leaf drooped, all around the neighbours plants were scorching. For WA in general, wicking beds rock, also great for curcurbits which need bottom watering to help avoid fungal diseases.

Why do I have almost all male flowers and only one or two female. I only have 4 plants growing. Thanks
