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.

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.

Hi, our house is on rock so we have very little garden. I have been trying to grow buttercup in large pots with varying degrees of success. I was wondering why sometimes the fruit or females are yellow as soon as they start to form.

Hello Jenny, The most likely cause is they haven't been pollinated. When a female flower opens pick a male flower and carefully remove the petals then put the male part of the flower onto the centre of the female flower and turn it slightly to transfer pollen (male sex cells) onto the female flower. Insects would normally do this but a shortage of bees will affect pollination rates. Pumpkins are hungry and thirsty plants so ensure watering is consistent and that they are well fed. Trust this helps. John

Thanks John I am aware of the pollination process. What I want to know is why the females are yellow as soon as they form ie really tiny buds, they are yellow as soon as they show on the vine.

Sorry, I haven't got a conclusive answer for you. I have done some research and found that female flowers often don't set early in the season and also that they can be stressed by heat or dryness and not set. Sorry I can't help you more

Hi, my female flowers and small pumpkin are going brown and falling off anywhere in size from and marble to squash ball size. The plant is quite vigorous but have started getting yellow spots on the more mature leaves. have fertilized with granules with trace elements but do I need something else. it is planted in a raised bed near a brick wall.

Are their enough bees to help pollination? If the female flowers are not pollinated, this fruit drop can happen. Tou can hand pollinate them.

I live in suburban Adelaide can I use a slow release fertilizer on my pumpkin seedlings and how often should I water them?

Growing pumpkins here in Gracemere CQ. Has always be a difficult crop because of the powder mildew fungi , over watering the soil seems to be the main action that is the cause of this problem .pumpkins need to be kept moist but not damp. This year I am trying to water under ground method and covering the soil around the plant so as to stop the damp rising towards to plant leaves . . I will see if this will help ?

Paul, try spraying the leaves with a mix of 1 tablespoon of full cream milk to 1ltr of water to get rid of the powdery mildew. The underground watering should help also. Cheers, Rob

Hi y'all, What is the reason that pumpkins should not be grown in the same plot as potatoes? How far separated do they need to be? Best wishes, John
