  • 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.

We live in NSW, and have got some butternut pumpkin seedlings that we have grown from seed (we weren't sure if they'd grow but have). Do they have a chance at growing sucessfully, or is it too early for them to grow due to winter?

If you can hold out for a couple of months that will give the seedlings the best chance

It is fairly easy. A male flower has a single central stem in the middle of the flower. Like a small pencil. It has a sort of yellow pollen on it. A female flower has a circular thing in the middle of the flower. If you want to hand fertilise you just break off the male stem and stick it in the female thing and rub the pollen off. It is the same procedure as for all life I suppose.

I have a kent pumpkin vine that is producing huge fruit. The vine is still very healthy, but the pumpkins are easily 5kg each already and don't show any signs of slowing their growth. Any tips on when to harvest? I don't want to lose the lot, but i also don't want to pick too early. I live in central QLD and we have had a fair wet season.
