Expert tips
The key tip
Pumpkins need rich, deep soil: amend generously before planting with 10 cm of compost. Water copiously but avoid wetting the foliage (powdery mildew risk).
The common mistake
Planting too densely: plants compete for water and light.
The pro's trick
Pinch the tips of each vine once 3-4 female flowers have set to concentrate energy on the fruits.
Care
Exposure
Pumpkin requires a location in full sun, with a minimum of 6 to 8 hours of direct sunlight daily. A south or south-west facing exposure promotes the production of sweet, well-developed fruits. Avoid shaded or overly windy areas that would slow growth.
Watering
Water regularly and deeply, especially during fruit formation: the soil should remain moist but not waterlogged. Favour watering at the base in the morning to prevent fungal diseases. During dry periods, watering every 2 to 3 days is necessary.
Soil Preparation
Prepare rich, well-draining soil amended with compost or well-rotted manure. Pumpkin prefers slightly acidic to neutral soil. Good drainage is essential to prevent root and fruit rot.
Fertilizing
Enrich the soil before planting with well-matured compost. An application of balanced fertilizer (NPK) during flowering and fruit formation optimizes yield. Prefer an organic approach with regular additions of composted matter.
Pruning and Training
Pinch the tip of the main stems after 2 to 3 metres to encourage branching. Remove excess male flowers and limit the number of fruits per plant (2 to 3 maximum) to obtain larger pumpkins. Keep stems on the ground for better rooting of the nodes.
Diseases and Pests
Watch out for powdery mildew and moulds: ensure good air circulation and avoid wetting the foliage. Slugs, aphids and squash bugs can damage young shoots and flowers. Thick mulching and regular inspections prevent attacks. In case of serious problems, favour biological solutions.
Did you know?
The pumpkin, originating from North America and Central America, has become emblematic of European autumn. According to legend, it was the pumpkin that inspired the tale of Cinderella: the magic pumpkin transformed into a carriage. In reality, pumpkin and squash are two different species, but both belong to the genus Cucurbita and share this timeless folkloric prestige.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
