Tips & Best Practices
- Count back from your desired harvest (usually October) to determine planting date.
- Direct sow 1–2 weeks after the last frost, or start indoors 2–3 weeks before transplanting.
- Pumpkins need lots of space — vines can spread 20+ feet.
- Reduce watering as fruit ripens to concentrate sugars and toughen the rind.
