(Best months for planting Pumpkin in New Zealand - cool/mountain regions)


  • Harvest in 105-140 days
  • 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.
  • Space plants: 90-120cm

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.

Culinary hints - cooking and eating Pumpkin

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

I was told I should "pinch" the end off leaders once a few flowers have set. Is that a good idea? How do i do it? Thanks!

Have just moved into a house in Hamilton. Have pumpkin growing and it is spreading over the rest of the garden, on to path, onto lawn. What is the process for trimming the leaders off. How do I identify which have the pumpkins on.Would value your comments as I have never grown pumpkins before.

Can you pick pumpkins before the plant dies off? Some of my plants are starting to change colour, like they are rotting?

You can pick your pumpkins if they sound hollow when you rap them with your knuckles and look ripe. Make sure that you cut them with a piece of stem attached.

My first pumpkin of the season had a bitter taste when I made it into soup. What might cause this to happen?

Is it possible to store pumpkins in a chiller, temp. around 2-5C?
