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.

I've bought some Halloween pumpkin seeds to grow for Halloween 31/10) this year, it's late May now, when's the best time to plant these so they're ready a few weeks before Halloween?

I put my seeds from my bought pumpkin into a glass of warm water overnight then planted them next day into my vege patch. They were everywhere !

I put the kitchen vegie scraps in a blender (with water) and strain it through shade cloth then add the vegie scraps to my worm farm. The pumpkin seeds aren't smashed up and the other week I had about 50 seeds germinate.

I have pumpkins that have come up in my garden .They came up in November and are white skins at the moment.I live in Rangiora North Canterbury.I don't know anything about growing them.Do I leave them in as long as possible as I don't know whether the frost or rain will affect them. Thankyou

Hi Toni you can stop watering your Pumpkins now. After you have a frost the leaves will die off. After the leaves die off you can harvest them any time now. Leave the stem on and store in a place with good air supply and sun to ripen. You can check the ripeness by knocking on them with your knuckles listen for a hollow sound which indicates ripe. Enjoy Jim

I grow pumpkins every season. If you want your pumpkins to grow big you must make sure the entire plant gets watered and fertilised regularly as the vine sends down a root at about 1/2m intervals in search of water and food. When you start getting female flowers (with a pumpkin attached) you need to fertilise them by getting pollen from the male flower, just put your finger inside and you will see the pollen on it, gently brush it on to the middle of the female, once pollinated the new pumpkin will go into a growing frenzy, (I know they are about 90% water ) Water, water, water! And food, My best Kentia/ Jap went 12.2 kg 33cm high, save the seeds and keep them in the freezer. Veggies are the best.

My pumpkins plants get big beautiful blooms, only to fall off. Is this bloom blithe, or a pollination problem etc.? ,

Hi I planted pumpkins in mid November, they are still growing and i'm getting heaps of them. Do I just let them keep growing until they decide to dry off from the stalk? I live in Launceston,Tasmania

My Pumpkins are the same. Still growing like crazy and flowering. I thought they are supposed to be finished? This is my first time growing them down here (Victoria). I guess we'll just have to leave them until the plants die off.
