How do l tell the difference between male and female flower

Have a look at the thing growing inside the flower. Does it look like a male thing or a female thing? I think this will answer your question.

Female flowers have a tiny pumpkin at the base of the flower, males just have stem.

Why do my pumpkins get to the size of a fifty cent peace and go yellow and drop off

They haven't been pollinated. Try transferring pollen from male flower to female flower.

What is the best method to pollinate? Using a cutip?

Can you let myself know how well pumpkins grow in South Canterbury, NZ? Is it possible to grow pumpkins all around N.Z.? JW Connelly

Select your climate zone, then go to the vegetable you want and then look up the planting guide. NZ cool climate plant Oct to Dec.

Hi there, I am in Sthn Gold Coast. Am I able to plant a butternut pumpkin in a very large pot (for root growth) and then let the vine trail over into the garden. My soil isn't very good, by using a pot I can buy good quality soil / potting mix. Would this work? Thank you, Sam.

Yes it would work - need to water regularly and also fertiliser now and again. Amazing what a little compost and fertiliser can do to poor soil.

Just found this - commercial production. For efficient pollination and fruit set, there must be: both male and female flowers and bees to move pollen from male to female flowers. A number of factors can influence pollination, Cold and overcast days limit pollination activity of bees. Hot dry conditions desiccate pollen making it unviable. Rapid growth promotes earlier flowering. However, high temperatures, long days and high rates of nitrogen can result in: vigorous vegetative growth and few flowers and a higher proportion of male to female flowers. It is important to check the sex of the flowers. A ratio of 1 female to 7 male flowers is usually considered adequate. Flowers open early in the day and for one day only, and they close by mid afternoon. These periods are shorter under high temperatures. Flowers are most receptive to pollination in the morning when bee activity is usually the highest. Bees are necessary for pollination and must be active in the crop. Flowers require at least 12 bee visits for good pollination. If bees are not plentiful, introduce at least two hives per ha after female flowers appear and male flowers start producing pollen. Spread hives around the field outside the crop, preferably so that bees have to fly over the crop to get to another food source. Destroy flowering weeds around the crop.
