To plant squash seeds, sow them about 1/2 to 1 inch (approximately 1.3 to 2.5 cm) deep in the soil. This depth is suitable whether you are planting seeds directly outdoors or starting them indoors in pots or seed trays. Planting at this depth ensures good soil contact for moisture retention and proper germination. Seeds typically germinate within 7 to 10 days if the soil is warm enough, ideally around 70°F (21°C)
. When planting outdoors, space the seeds or seedlings 12 to 18 inches apart for summer squash, allowing room for the plants to grow large. For bush varieties, space planting sites about 3 feet apart, and for trailing varieties, about 5 feet apart
. In summary:
- Plant squash seeds 1/2 to 1 inch deep.
- Space seeds 12 to 18 inches apart for summer squash; larger spacing for bush or trailing varieties.
- Ensure soil temperature is warm (around 70°F) for best germination.
- Seeds should sprout in 7 to 10 days under proper conditions
