Can a Butternut Pumpkin be grown from a top only, and what would be the best method? I'd love to try it if there's a chance it may work. Thank you kindly.

I don't see it working. Stick some skewers in it and hang it in water.

Surprisingly I have pumpkin seeds growing in the shadehouse ??? Is there anyway i can encourage their growth or are they doomed

I would like to grow some pepitas or other breed of squash that has an edible seed. Can you reccomend a type and tell me where i can buy seed, cheers Lindsey

Hi Lindsy. Try Kings seeds, they have two types of oil seed pumpkin (that is the type you want). Austrian Oil Seed Pumpkin and Pumpkin Lady Godiva. Be careful with the water when sowing the seed, as they have no husk they can rot if the soil is too wet.

I have grown my first pumpkins this year, and they hung on the vine. Amazing, 3.8kg hanging! Now, my question is: if I store them outside, will the possum eat them? Thank you in advance

Possums ate mine - so did the rats! So you need to store them where these sharp-toothed creatures cannot reach them.

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.
