Growing Pumpkin in Queensland

Introducing Pumpkin

This warm season crop needs plenty of space, but grows vigorously with few problems. Plant your pumpkins in a sunny spot with rich soil and they’ll reward you with an abundant harvest.

Classic Mistakes

Make sure your pumpkins get enough sun and have enough space to grow.


Grow in: Full Sun

Soil Preparation

Pumpkins like a rich soil. Work in plenty of compost and well-rotted manure.

Sowing Seed

Sow seed: August-February
Sowing depth: 10mm

Pumpkins need warm soil to germinate, so plant your seeds once the soil is nice and warm.

Sow your seeds into mounds about 1 m apart. Once the plants are up and established, choose the strongest 2 plants and remove the rest. Pumpkins are best planted from seed. They don’t like to have their roots disturbed.


Plant seedlings: All Year Round

Seedlings can be planted year-round, but will do better in warmer weather.

Pumpkins don't like to have their roots disturbed, so work gently with them when you plant them out.


Once your vines reach the desired length, pinch out the growing tips to prevent them from growing longer. This will encourage them to branch out.


Pumpkins like moist soil and won’t need to be watered much in the wet and humid Queensland summer. You may need to water your pumpkins if you live in a drier area of Queensland that has less rainfall. When watering, its best to try not to get their leaves wet, as they are prone to fungal diseases. If you must wet the leaves, water them in the morning so that the leaves can dry off quickly during the warmth of the day.


Pumpkins are heavy feeders and benefit from regular feeding. Feed with a balanced organic fertilizer every 4-6 weeks throughout the growing season.


Mulching helps to keep the soil moist and cool. Apply a generous layer of organic mulch such as shredded leaves, straw or coconut husk. Since pumpkins are such heavy feeders, so a compost mulch is also a good option.


Harvest: 15 to 20 Weeks After Planting

Pumpkins can be harvested once their skins have hardened and thickened. Pick mature fruit as you need them. Use a sharp knife to cut them away from the vine. Be sure to leave a piece of stem attached to each pumpkin. If you want to store your pumpkins, only harvest them at the end of summer so that their skins can become hard and thick. Pumpkins should be cured before storing.

What to do about Snails and slugs?

Lay down grit, like eggshells or silica sand or create barriers around your plants. Remove any slugs or snails that you see.

What to do about Powdery Mildew?

Milk spray or baking soda solution work well and can be sprayed on affected plants.
