  • Space plants: 35 - 47 inches apart
  • Harvest in 15-20 weeks.
  • Compatible with: Sweet Corn
  • Avoid growing with: 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 Diane, I'm in the Shoalhaven and I plant mine Sept/Oct. We' have a bumper crop each year. I think once the frosts have finished in your area and the days are warming a bit is fine. Cover them compost and mulch to give them a bit of warmth to start with.

I tried growing pumpkin in composted soil and have 4 tiny pumpkins which stopped growing. How do I get larger fruits in future?

They are not getting pollinated, you need to get a feather and dip it in the flowers that don't have a pumpkin on them, then gently stick the feather into the ones that do.

It's nearly end of April & we had our 1st frost last night & my jap pumpkin plants have turned up their leaves we've only got 2 pumpkins but I don't believe they are ripe yet so do I leave them or take them off?

Put bricks or the like underneath them to get them off the ground, but don't pick them until the stalks turn brown, this is the sign they are ready. If the stalks are green they are still getting nutrient from the plant

Planted potkin & Qld Blue pumpkins. They all keep going yellow and dying when they first form. Does anybody know why this keeps happening please.

My vines develop small green pumpkins and after a week they turn yellow and fall off the stem. What is the problem?

I've had the same problem this year so would be interested to hear from others!
