As with most vegetables, when planting pumpkin, it’s important to take into account the climate of your region.

December is the last month that it is recommended to plant pumpkin seeds in Melbourne.

Here’s why:

  • Pumpkins grow best in temperatures in the range of 20°C to 35°C.
  • A pumpkin takes around 3-4 months from planting to harvest.
  • Therefore, if a pumpkin is planted after December, it will still be growing in March/April, which in Melbourne is too cold for optimal growth.

Pumpkin FAQ

Does pumpkin need full sun?

Yes, pumpkin will grow best when it receives at least 6 hours of direct sun per day. This is especially important in cooler climates.

How do you harvest a pumpkin?

To harvest a pumpkin, cut it off the vine with a sharp knife or secateurs. Do not tear it off as this will damage the fruit. The goal is to keep your pumpkin as healthy as possible until you are able to use it for cooking, so take care not to damage it.
