    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.

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.

In HB, pumpkin planting of seeds you've stored from last year gets underway in early October. They're easy to grow, plant deeper than 3 cm if birds may dig them out. They will ramble everywhere in your garden! ....Plant mandarins before November. Mandarins do fine semi rural in HB with no frost protection. But once a year, you need to spray them with oil as they can get sooty mould. The sooner you spray the better if the leaves start showing this black mould as it spreads. I hate spraying if there are bees around so check this out first. I underplant citrus with allysium as this little flower is meant to discourage bugs.

Like all curcubitae, planting time is when your soil is up to 20C. Definitely after all risk of frost is over

From time to time I will have a pumpkin from my garden that when I cut it, it has white lumps in it that are hard and when the pumpkin is cooked it remains hard. Do you know what causes this, maybe something in the soil? something lacking in the soil? a virus? I would love to find out and see if I can avoid or cure this problem.
