When to plant or sow Pumpkin?

Pumpkins demand full sun and rich, moisture-retentive loam to produce their famously large fruit. Choose a sheltered spot with at least six hours of direct sunlight daily. In temperate Europe, sow seeds directly outdoors in May once all risk of frost has passed and soil temperature reaches at least 12°C. Alternatively, start seeds indoors in late April in 7–9 cm pots, sowing two seeds per pot on their side about 2 cm deep, and transplant the strongest seedling after hardening off in mid to late May. Prepare the planting site thoroughly. Pumpkins are greedy feeders, so dig in at least two buckets of well-rotted manure or garden compost per square metre a few weeks before planting. The soil should be free-draining yet able to hold moisture; heavy clay benefits from added organic matter and grit, while light soils need generous compost to improve water retention. Space plants 150 cm apart in all directions—pumpkins sprawl vigorously, with vines reaching 2–4 metres, and crowding invites fungal problems and limits fruit size. Plant or transplant so the base of the stem sits just above soil level to reduce the risk of stem rot. Water in thoroughly after planting, soaking the root zone deeply. Immediately after planting, apply a 5 cm layer of well-rotted compost or straw mulch around each plant, keeping it clear of the stem itself. This suppresses weeds, conserves moisture, and keeps developing fruit clean. In exposed gardens, consider using cloches or fleece for the first two weeks to help young plants establish in cooler May weather.
