  • 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.

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.

Pumpkins are best planted when soil temperatures have reached 15-17 degrees C. This varies between climate zones, Australia is a large country. A soil thermometer is aa good investment to check this. They usually cost around $20.00. If you plant seedlings in February you would need to have about 4 frost-free months to harvest. As for ethics many companies sell what looks good or what people want. Tomato plants are available in Victoria as early as July. They will not do well until mid to late October when the soil has warmed up and many will die. This suits the seedling growers as they will sell more plants as replacements. Having said that if you have a sheltered spot you could get tomatoes going earlier. The best thing to do is to check the planting times on this site relevant to your area and don't be tempted by what's on offer.
