I have the same problem as w Watson with plenty of male and female flowers but no fruit setting. I've tried hand pollinating but the male flowers don't seem to have any pollen. Anyone know why or have any suggestion? Thanks

I have had hit and miss with hand pollinating the last two months. Then again if all female flowers hand pollinated set fruit I would have 30 or so pumpkin on 2 vines. I have come to the conclusion that you look for male flowers that are a few days old. When you pick a male flower just touch the stamen to see if there is pollen on it (yellow powdery stuff). I feel the new male flowers don't have mature pollen. Use 2-3 male flowers and give it a good gentle rub around the inside of the female flower and on the end of the pistil. I don't normally grow pumpkin but have given it a go this year. A big learning curve with no bees.

I always leave the skin of pumpkins on when cooking. I eat it along with the pumpkin, its delicious and is also where the nutrition is...especially on roasted! If you dont wish to eat the skin for whatever reason its easy to scrape the flesh off the skin when cooked.

I have a 3x3 m patch of garden where I had potatoes. I've harvested all of these now. Would it be unwise to grow pumpkins there next?

It says don't grow next to each other. I would think if you had no or little disease with the potatoes then you might have a successful pumpkin crop.

Are pumpkins short-day plants? Mine are spreading all over the yard, but there are still no flowers. I've forced early flowering of other short-day plants by covering them in black plastic every second evening and keeping it on the next morning to create a twelve hour night for them and it's worked well, chokos being a good example, but I can't find anything to suggest pumpkins react the same. If no one has the answer I suppose I'll just get myself some black plastic and try for myself, but with some 40'C days around I'm hesitant.

I think you are on the wrong track with length of daylight hours. I have plants growing now. Just hand pollinated a dozen or so female flowers last week. My vines are 4m+ long. Maybe you have given them too much Nitrogen. 40c would probably cook them under black plastic.

Well I don't know if it was just coincidence and time for the pumpkins to start flowering anyway but after five nights of covering most of the pumpkins with just a light weed mat instead of black plastic, those covered now have 2-4 male flowers on each. No sign of female flowers though! The one I did not cover still has no flowers. I put the covers over at around 7.30 pm each evening and pulled them off anywhere from 8 am to 9.00 am the next morning giving them roughly only 11 hours of daylight.
