Hi, I have a raised bed which had beetroot and tomatoes last season. Noticed a strange plant and decided to let it grow (from curiosity) but it turned out to be pumpkin and has taken over the raised bed despite constant "culling". It has produced quite a few flowers but they just close and fall off. The foliage is very healthy and the flowers numerous (being in a composted bed). My question is - if the season is over by December is it worth letting the plant(s) continue to grow and produce flowers if there is no chance of forming fruit? I have seen only a few bees and tried self-pollinating but nothing seems to be moving. Would appreciate your comments on this.

Pumpkins will not be likely to ripen in temperate areas now as Autumn is setting in. It is better to get an early start in the season, around October to ensure a good crop. Any small pumpkins on your vines could be harvested and treated like zucchinis. Sadly our bee population is declining rapidly. Providing host plants around your garden will help. These include any of the 'daisy' type flowers, a lot of herbs and lavender.

My pumpkins (like many others in this are) have only just flowered and have set a large crop of pumpkins that are only just the size of a golf ball although some are double that size. Should I persist and hope for a mature crop or bite the bullet and pull them all out?

There is not a lot of chance getting a crop of pumpkins now as Autumn is setting in. harvest all the small pumpkins that you can and treat them like zucchini's (they are in the same family) and start earlier next season. In a lot of areas we haven't had a lot of Summer to help development and ripening.

I am retired and live in Masterton and would like to grow pumpkins for a little extra income.My father grew triable variety in New Plymouth.Can they grow down here. Thanks

You should be able to grow pumpkins successfully in Masterton. About four years ago a little chap (3) from Masterton won the biggest pumpkin competition run by Mitre 10. To get a good start plant the seeds in toilet paper cylinders filled with potting mix and kept on a sunny windowsill. You could start them in mid-October ready to plant out in early November. Plant the cylinder as well to save any root disturbance (it will rot). Triamble is a great old variety. If you can get seed of 'Queensland Blue' it will probably give you a higher net yield per plant at an average of 17 kg. Properly ripened pumpkins always sell well. Try pubs, restaurants, etc. All the best.

Hi. A friend once gave me a triable pumpkin, it was firm when cooked and very tasty. He said that they take a long time to mature

Good Day which month is good to plant "Halloween Pumpkin"

The best time to plant pumpkins, squash, zucchinis, cucumbers, etc is when the soil temperature is 15-17 degrees. This is around the end of October in the southern states. Many people say 'after the Grand Final' or 'Melbourne Cup' time.
