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

Try growing them early in the planting season. Start seedlings in August Sept. Mulch around the plants and give a good watering twice a week. I don't grow things in summer too many problems. You probably have some disease or grubs. Do some research on the net.

I have pumpkins that have come up in my garden .They came up in November and are white skins at the moment.I live in Rangiora North Canterbury.I don't know anything about growing them.Do I leave them in as long as possible as I don't know whether the frost or rain will affect them. Thankyou
