Squash seedlings do not really transplant that well, but it can be done if you are careful. Start transplants at least 3-4 weeks before last spring frost. Sow 2 or 3 seeds 12 mm- 2.5 cm (½-1”) deep in pots. When the seedlings are 5-7 cm (2-3”) tall, select strongest seedling and thin to 1 plant per pot using scissors. Harden off seedlings gradually by cutting back on water and expose them to sunlight daily. Seedlings should have more than 2 to 3 true leaves prior to transplanting outside. Transplant once the soil is warm up to at least 15-21˚C (60-70˚F). Plant 2 transplants per hill. Space hills 2.4-3.0 m (6-10’) apart. If planting in rows space seedlings at 61-91 cm (24-36”) apart. Space rows 2.4-3.0 m (6-10’) apart.
Direct sow seeds into garden from late May to mid-June. Sow 3 or 6 seeds 12 mm- 2.5 cm (½-1”) deep into hills that are 2.4-3.0 m (6-10’) apart. Thin seedlings at 2 per hill.
