    Harden off for 7 days — a little more sun each day — before planting. That's the difference between a seedling that thrives and one that stalls.

  2. Outdoor sowing time: delicata squash

    Keep the top inch of soil moist until germination — a gentle morning watering for 5–7 days does the job.

  3. Sow delicata squash in trays indoors

    Bottom-water once the first true leaves appear — it keeps stems dry and knocks back damping-off.

Delicata Squash Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Delicata Squash needs ~1,305 GDD — county provides 2,523 GDD Excellent fit
