How do you know when they are ready to harvest
10 Jan 19, Jacob (New Zealand - cool/mountain climate)
Wait till the plant dies before harvesting.

Above it says 15-20 weeks to harvest. Take notice of when to plant and how long to harvest.

I have lots of pumpkin flowers but only one pumpkin has formed. A friend mentioned male and female flowers. Can/should I remove flowers that aren't going to produce fruit?

If you go to the Australian - sub-tropical zone - there is quite a bit about this with pumpkin. Pumpkin produce male flowers first then they have female flowers, The female flower is only open for one day (until about mid day). No bees no pumpkin. So hand pollination is required. Take about two male flowers and rub the female flowers with it. Look up the internet on how to do it. This applies to zucchini, cues and melons also I believe.

My pumpkin snapped off the vine. It is very large but the vine is still healthy. What do i do with the pumpkin to ripen it

Support the vine next time. If the vine had started to die back etc the pumpkin would have been ripe/mature - 5-6 mths old. If the plant had only been growing 3 mths then the pumpkin would be immature.

had the same problem early in last season I put the pumpkin in a warm dry place in the garden shed and was left for 3 months decided to cut it and was surprised to see a fresh not fully ripe but very edible pumpkin, warm shed and dry seems to work

Can you grow gem squash in South Taranaki, New Zealand? When is the best time to grow them and how?

I live in Wainuiomata and have grown gems for two years running and I intend to plant a lot more this year. They were delicious. I planted the seed at the end of August and as soon as they had about 4 leaves, I planted them out in the garden, I also cut off the bottom of a coke bottle, took the cap off and put the bottle over the seedling until they were a little stronger. Hope this is helpful and good luck.
