  • Easy to grow. Sow in garden. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 68°F and 90°F. (Show °C/cm)
  • 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.

Hi guys, our neighbours are growing pumpkins (look like crown variety with pale skin and flat bottom) and the vines came over into our place and a nice big pumpkin grew, so of course I picked it right away not knowing anything about pumpkins. The inside was a weird pale yellow rather than orange, I presume now that I have just picked it too soon and it is unripe! Is that correct? Thanks.

Not a problem if it is unripe! can still make lovely pumpkin soup (I actually thin it is better with unripe pumpkin!)

Put some curry in it to give it some taste. lol

Check with your neighbour next time. Next time wait until the stem has become hard and woody. About 16-20 weeks after seeds germinate.

I have 3 healthy pumpkins growing on the vine but the new baby ones are going yellow and dying. What causes this?
22 Jan 19, Liz (New Zealand - temperate climate)
They are going yellow and dying because they have not been pollinated. Try using a soft small paint brush, or something similar, to transfer some pollen from a 'male' flower (one without a tiny pumpkin behind it) to a 'female' flower - one with a tiny pumkin behind it.

Thanks for that, I assumed that if a pumpkin formed it must have been pollinated.
