Thanks for your response. my space is limited to grow pumpkins as they take up alot of room so the idea of vertical seemed good. Yes I agree I am bit concerned about the grow bag being sufficient as yes agree need to keep water & feed up which I am used to as have had lots of pots. This is a little bit of an experiment for me so will see how it goes the seed were from another pumpkin so I will try & hope for the best.

There are probably pumpkins that require a smallish area but most pumpkins require an area about 4m square. You could try a grow bag but I would never do it. I watched a TV show, Garden Gurus last weekend, show how to grow tomatoes in one. They planted 3 plants in a bag about your size or a little bigger. They planted them 15-20cm apart. ONE tomato plant needs an area approx. 60cm radius and 40-50cm deep. I plant 4 tomatoes along a 2.5m trellis. My suggest is if you have a small area then plant smallish crops. At home I have 13m x 2.5m and I do not plant any vine crops.

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.
