Aspen Hybrid Pumpkin Seeds 2040. Aspen is a semi-bush variety producing 3 to 5 pumpkins per vine. Spherical fruits are a dark orange colour averaging 8-9 kg (18-20 lbs) and 25 cm (10″) across. Aspen produces a strong, heavy handle and stores quite well. As pumpkin seed does not tolerate cool soil, it is best to wait until the soil warms to at least 25 C (77 F) before sowing directly to the garden. Straw mulch helps prevent damage to fruit caused by contact with wet soil. Grows best in rich well drained soil. Avoid heavy clay soils.
How to Grow
Pumpkin is a hot weather crop. They need full sun and deep, rich, well drained, organic soil with a pH of 5.5 to 6.5. Before planting, work in lots of compost. Sow seed directly outdoors from late May through early June 2.5 cm (1″) deep in hills 2.4 m (8′) apart with 4-6 seeds per hill. After germination, thin to 3 plants per hill. Seed can be started indoors 3 weeks before the plant out date. Pumpkins do not transplant well–use paper or fibre pots that can be set directly in the soil. For competition sized pumpkins, allow only two pumpkins per plant to mature. Protect mature pumpkins from frost and cold temperatures.
