  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • P = Sow seed

September: Frost tender

  • 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 20°C and 32°C. (Show °F/in)
  • Space plants: 90 - 120 cm 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, try picking a male flower (straight stem) and gently brushing pollen inside female flowers.

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.

has anybody ever grown a pumpkin vine up a pergola or clothes line with any success, and if so, how is the best way to go about it? thanks.

brendan - have not tried the clothes line, but have tried a pergola of sorts. Grew vine up on to shed and worked a treat, higher, more sunlight.

possums eating my pumpkins had to cover with fruit netting worked well

Brendan, I have seen a pumpkin vine that took over a paling fence Approx 15mts. But all the fruit grew on the neighbours side. Lucky we got to share

About hand pollination can you please give me some more info on the best practice on doing so??? Thanks

Are pumpkins heavy feeders? What do they like? In the soil I mean.
03 Oct 08, Warren (Australia - tropical climate)
Liss, Pumpkins are not really heavy feeders in my experience also to seem to require little water. They really like sulphate of potash, that can be either burnt ashes or a comercial product. A few watering every 3 or four days will keep them thriving. A point to remember is that when the fruit begins to develop don't increase the water or the fruit may split. Hope this helps. Warren

Hello Pumpkin Growers I am attempting to grow pumpkin for the first time. Do I need to grow at least 2 plants? I am not sure if the plants have both male and female flowers, or are single sex? Any tips appreciated; I do realise I will have to "encourage" pollination.

Geraldine, each pumpkin plant should produce both male and female flowers. The earliest flowers that emerge will be male and all up there will be more of them produced in total than female. You may or may not have to encourage pollination. If you have bees hanging around they'll do it for you. Consider making your vegie patch more enticing to bees by companion planting some bright flowers (like calendula, nasturtiums, french marigolds, sunflowers, etc) to attract them. Anyway, the way to tell the difference between male and female flowers (in case you didn't already know) is that female flowers will generally have a bulbous base near the stalk, below the flower. Also, since they take up a lot of room, have you considered training the pumpkin vine along a fence or up the side of a garden shed? A workmate of mine had them fruiting up on his shed roof last summer.

How many pumpkins can I expect on each plant? Thanks

Last year 2014 I planted some Queensland blue Pumpkins at the end of the harvest I picked 22 pumpkins, but much to my dismay a lot of them were very woody why would this be can any one give me an answer as they weren't very good for pumpkin soup. Cheers Bazza
