  • Easy to grow. Sow in garden. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 68°F and 90°F. (Show °C/cm)
  • Space plants: 35 - 47 inches apart
  • Harvest in 15-20 weeks.
  • Compatible with (can grow beside): Sweet Corn
  • Avoid growing close to: Potatoes
  • 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.

Hi, I’m curious about the advice not to plant potatoes and pumpkin together. Some sites seem to suggest that the two won’t do well if planted too close together. Is that right? I have a large potato patch (about 40sqm) and was planning to plant pumpkin in about 2sqm at one end. Would that be a mistake? Thanks

A few pumpkin plants would need half your potato patch to grow in - not 2 sqm.

Some plants produce chemicals in the soil or extensive root systems which affect other plants. The advice is generally to avoid planting curcubits (pumpkins, courgettes etc.) and potatoes together. If you have room grow them in separate plots.

Hi :) this is my first go at pumpkins so I planted my own seeds straight from my pumpkin I placed them in a pot that has a maple tree. When should I move these sprouts please

After they produce their first or second set of true leaves. Protect them from the sun the first few days when planting out.

I have the same issue... but i planted in May and apparently should have in February so trying again next year! Did you ever figure it out?

My mum made me put 2 seeds in the same spot, will that ruin the pumpkins?

It is probably so that you can choose which plant is stronger and remove the other one. Ask your mum why.

I just planted pumpkin in 10 spots with 2 seeds at each spot. Only 2 spots had 2 plants germination. Sometimes it is for germination reasons. I basically had the same result from apple cucumbers.
