  • 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.

Hi is sept with warm temps too late to plant pumpkins?

It is about 4 months too late by the guide here. It is not the temps now but what they will be in 4-5months time when the pumpkin are suppose to mature.

I read that they can have trouble pollinating without a little help, though I haven't started growing mine yet.

Because of the heat in zone 9a. Plants have difficulty pollinating when temperatures are 90 degrees or higher. In Southern Nevada temps got to 120 degrees. I plant seeds especially seedlings once temps are below 90 degrees. When temps are high I use Blossom Set to help the fruit to set on

If you don't have active bees when they flower then you can hand pollinate. A female flower is only open for a few hours one day, if not pollinated then no pumpkin grows. Google how to do it.

I was hoping to plant some pumpkins, but I am worried they won't grow very well since it is almost the middle of July. Can I still plant some in my garden? I live in a very warm climate too.

I think you should still get decent pumpkins in zone 8. Because it's so hot right now they should grow quickly, much more quickly than if you'd planted earlier. Make sure they have plenty of water, though, and mulch them so they don't fry. Good luck!

Hi my name is Caroline and I’m not from New Zealand, but I love pumpkins! I REALLY REALLY have the urge to carve a pumpkin but unfortunately they are all out of season in America. This might sound stupid but are pumpkins on the same schedule in New Zealand bc of the difference in climate? Like would I be able to get one shipped ?
