(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.

KamoKamo baked in the oven with, or without a roast, is also nice filled with stuffing, then wrapped in foil. Ryan, I agree...it is about the nutrients, after all

We cook our Kamokamo by steaming them when young. Delish!

I would like some advice on growing giant pumpkins please. From seed to the table.

A question. Our pumpkins are doing really well but we are wondering if we can trim off the growing tips now so that all the remaining growth goes into the formed pumpkins.Our weather is getting cooler and we won;t get any new ones come to fruition.Help please!

Please help. Out of 20 odd pumpkins forming on our plants, about 15 went rotten while still very small. We have pea straw down and I water every day.

Cherry, it sounds as though your pumpkins are not being pollinated. You can do it by hand with a small soft brush. Touch the pollen from a male flower (one without a miniature pumpkin behind it) and gently brush the pollen onto the centre part of a female flower.

Why are my pumpkin plants only forming female flowers? Not one male flower to be found. Needless to say, crop a complete failure!

Male flowers usually appear first followed by the female which have a small bulb at the base of flower. Hand pollination recommended if lack of bees.. Small pumpkins that rot off are usually result of non-pollination.
