  • Space plants: 35 - 47 inches apart
  • Harvest in 15-20 weeks.
  • Compatible with (can grow beside): Sweet Corn
  • Avoid growing close to: Potatoes
  • Pumpkin on vine

A large trailing plant with yellow, bell-shaped flowers, pumpkin is frost tender. Most varieties will take up a lot of room . Grow them at the edge of your garden patch so that they can spread away from other vegetables. Butternut produces small to medium pear-shaped fruit with deep orange flesh . Buttercup are small to medium round pumpkins with dark green skin. There are a number of large pumpkins, some round and flattish - good for storage and eating - others will produce the "Cinderella coach" type giant round fruit which are not such good eating.

Harvest when the vines die off and the pumpkins' stalks are dry. Leave a small piece of stalk attached to the fruit to prevent damp causing rot. The fruit can be stored for months in a cool airy place. In some parts of New Zealand, they are stored on shed roofs.

Pumpkins sometimes need hand pollination if the fruit are not setting well or die off after starting to grow.

Culinary hints - cooking and eating Pumpkin

Cut up, remove the skin and roast with other vegetables or meat.

Young crisp shoots with young leaves can be cooked and eaten - stewed in coconut milk they are popular in Melanesia. Remove any strings and tough parts and stew until tender, or cook as a vegetable in boiling water 3-5 minutes.

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

I have pumpkins coming up now from garden compost. Is it too late to let them grow?

Depends what climate zone you live in, what type they are and if you have cold conditions and frost. They probably germinated due to the warmth of the compost so if they are in a warm sheltered position you could let them grow and see if they reach maturity. Then you will be able to keep the seeds as they will be acclimatised to local conditions and should always grow better than seeds introduced from elsewhere. All depends on if you have the room to experiment.

I have 19 butternut pumpkins on my vine and it is starting to die off, how long should I continue to feed the plant for and is it best to wait till the plant has completely dead before harvesting the pumpkins?

I live on the NSW South Coast in Australia and my butternut pumpkin gets pumpkins up to about 4 inches then they go yellow , die and fall off. Should I pull them out and try again next year.

Do some research on the internet butternut pumpkin turning yellow and falling off. Many reasons why it is happening.

I am trying to grow Queensland Blue pumpkins. They are next to a lavendar bush and well polinated. Lots of baby pumpkins, but they do not grow very big before they go yellow and die. Some of the leaves have gone brown, so I have removed them. Any thoughts on how I can remedy the situation.

Do not water pumpkin plants in the evening. If the leaves stay wet in the night, there are higher chances of powdery mildew.
