Grow in a different area next time.

Google it - organic or in-organic.

Organic or inorganic spray that is.

This year my pumpkins are quite robust, a good yield due to creating a beehive I reckon. But its very hot here in NE Victoria, the plants are struggling, despite 2 daily waterings and although the stems haven't dried off my instincts tell me to pick them before they get affected as well. Am I right or wrong?

If the stems haven't dried off fruit will be immature and tasteless. They will not keep .Leave on the ground. Risk of rotting is slight and worth the risk. If you are unduly concerned you could always lift the fruit off the ground onto a piece of wood or similar. I rarely lift mine until May / June. Graham (berwick Vic)

Go by the guide here of 15-20 weeks. But a good indication is the stem holding the pumpkin to the vine is woody and hard. Pick one of the oldest ones and try it - judge from that when to pick the rest.

Hi. We live in Zone 9. We were able to get beautiful pumpkin plants and florets, but never produced a pumpkin this year. We know they can grow bc there is a pumpkin farm nearby that produces plenty. I thought that I had only males, but then female plants appeared and still no flower. We started them in Late July, I think. Any advice?

My butternut pumpkins are growing well but when the pumpkin gets to a good size approx 100-150mm long it goes brown and dies off. It is about 38 deg here the last week and I water twice a day (morning and late arvo) Is it the heat or too much water or needs some fertiliser???

Hi Wayne, I planted my pumpkin seedlings last September and luckily it happened to be next to a lavender bush which attracts bees. It gave me 4 pumpkins which ended up growing under the lavender bush and next to the fence. I watered it a few times and then it just took care of itself. But they do tend to prefer growing under or around other plants for shade.

Hi Wayne, A possibility is they are not being pollenated. Are there bees in your garden? I would suggest pollenating the flowers yourself with your fingers gently. Touch the male, then touch the female flower. Good fun. Carl

I am just south of Townsville and planted Qld Blue pumpkin seeds in early April in good soil with correct PH levels. Plenty of space to run and good sunshine and watered daily. The plants grew well for about 6 weeks producing masses of mostly male flowers?? I had plenty of bees doing their job, but still only got two pumpkins that didn't reach maturity before the plants died off about 2-3 weeks ago. We did have a couple of 6deg nights but nothing lower. Any advice would be very much appreciated. Cheers
