Thanks for your reply, I was thinking the grow bag and then using a frame for the vine to grow up and do understand the points you made. I was thinking of it as a bit of an experiment as I have some seeds which have sprouted and was thinking of planting just 2 of the seedlings. Some sites gave differing opinions on them being a shallow rooted plant vs a deep rooted which confused me so i wasn't sure if the grow bag would be deep enough. Appreciate your response

Good luck, gardening is all about trying new things. My daughter has me growing sun flowers, first time in 40+years.

I farm in Heidelberg, Gauteng and would like to try pumpkin on a 17 hactre land without irrigating. Please advise me. (Gardenate says : This is not a farm advisory site. Contact your nearest agricultural department. )

I read that they can have trouble pollinating without a little help, though I haven't started growing mine yet.

Because of the heat in zone 9a. Plants have difficulty pollinating when temperatures are 90 degrees or higher. In Southern Nevada temps got to 120 degrees. I plant seeds especially seedlings once temps are below 90 degrees. When temps are high I use Blossom Set to help the fruit to set on

If you don't have active bees when they flower then you can hand pollinate. A female flower is only open for a few hours one day, if not pollinated then no pumpkin grows. Google how to do it.

Hi, I'm on the Central Coast of NSW. Is there any way of growing pumpkins so they're ready for Halloween?

It says 15-20 weeks so you are outside of that timeframe. The seeds need warm weather to germinate. and grow. You could try, the pumpkin grows pretty quickly then takes about 3-4 weeks to mature to eat. Need full sun.

How do I germinate by hand? Are there male and female flowers?
19 Jul 20, Liz (Australia - tropical climate)
There are male and female flowers. The female ones have a tiny pumpkin behind the flower. When you can see the yellow pollen in the male flowers, either pick one and gently rub inside the female flowers or use a cottonbud to collect pollen from the male flower and then rub in the female flower.

I haven't grow butternut but I have Kent pumpkin growing now. The vine did grow out about 1.5-2.0m before the male flowers came out, a few days/week later the female flowers should come out. Hope you have bees otherwise learn about hand pollination.
