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

Usually the un-pollinated little pumpkin only grows to about 50-70mm then shrivels up and dies. I had one grow to about 6

No I haven't been able to get any more Windsor Black seeds I only had a couple of seeds that were given to me, I planted them on the side of a very small hill in Heavy soil they grew and branched every where were getting male flowers And the female flowers were forming, but 10 days of solid rain the patch was absolutely saturated the rest of our property was flooded I thought they would be alright but thr female buds went yellow & dropped off. I prayed & begged for the vines not to die but 90% did.I was shattered. one vine in the row above it The McLeay Mongrel survived Another Victorian Pumpkin, was so sick I just forgot it, went down the Hill the other day the grass was 2 & 1/2 feet high and I trod on something in the grass and nearly fell over looked and found one McLeay Mongrel Pumpkin I have collected the seed from what has to be the weirdest Pumpkin ever, But probably the nicest eating Pumpkin ever, I would say it is probably the rarest as well. The McLeay Mongrel Is a very dry pumpkin with superb flavor much like Iron Bark sweeter & nuttier, I have looked at it it is more than likely a Triamble Iron Bark cross Maybe some Qld. Blue. I am offering 4 seeds up for Auction on eBay I do not have many seeds, so thought if I put a good reserve in them only the very serious growers would buy them. Be Warned it is not a pretty pumpkin but needs some serious pumpkin growers to keep it from extinction, it is a heavy solid pumpkin, looks like an Alien lava Rock. visit eBay Pumpkins just to see it. Regards. Sylvia.
