Cucurbita spp.


Plant after all danger of frost has past and when the soil has warmed to 21°C (70°F). Can be started indoors 3-4 weeks ahead of last frost date. Sow 1 seed into a jiffy pot and transplant out after all risk of frost has passed. For early plantings, use floating row covers to raise soil temperature, increase early growth and protect tender plants from wind injury. Sow 1" deep, 6" apart in rows 48-72" apart. Thin plants to 24-36" apart. Plant vining types at the edge of the garden to prevent the plants from over-taking the entire site. Space bush type plants 24" apart in rows 36-48" apart.


Full sun and a soil pH of 5.5-6.5. Moderate feeders; prefer a rich loamy soil of good fertility and moisture retention. Mix plenty of organic matter into soil. Even and sufficient soil moisture is essential. Pumpkins benefit from mild feedings with a fertilizer high in phosphorous to initiate fruit formation.


Harvest before a killing frost or when pumpkins are deep orange in colour. Simply cut from the vine leaving 4-6” of stem attached to the fruit. Store in a cool, dry area.

Pests & Diseases:

Striped and spotted cucumber beetles can be controlled with Rotenone or Trounce (pyrethrum). Powdery mildew can be prevented by using a sulphur or copper fungicide during humid, damp weather. Cold weather can influence fruit set and rainy periods often hamper pollinating insects.


Celery, corn, onion, radish.

Sowing Rate:

2-2.5kg required per acre for large seeded types.
