The unseasonably warm weather would certainly have helped keep the pumpkins growing but with the cooler nights of Autumn and Winter approaching you may not get them ripened in time. If you don't, just treat them like zucchinis or make pumpkin soup with them. Disappointing but you will get something out of them. For best results pumpkins need to be planted in late October to get a good long season in temperate areas.

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.

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.

Planted Karadle Gray pumpkins late spring, they are still growing and prducing female flowers. it is now late March, when will they die of so we can pick the fruits. Peter

The likelihood of them ripening is fairly slim unless you don't get any frosts until late May. The vines will normally start to die off when they are ready. If you run out of time use them to make pumpkin soup or grate them to use in place of zucchinis in cakes or savoury muffins. Next season plant your seed in toilet paper cylinders or egg cartons so they will be ready to plant out in late October. Plant cylinder or egg 'cell' as well as it will rot.

I see from the Gardenate planting guide that the planting time for pumpkins is September to December. I purchased butternut pumpkin seedlings from Bunnings in February. Is the selling of such seedlings out of step with the recommended planting season unethical? The seedlings have grown and there are currently 3 pumpkins visible. I am concerned that by planting them outside the recommended period they will not mature to completion.
