Direct Sowing (Recommended):

• Sow seeds outdoors after the last frost when soil temperature reaches 65-75°F (18-24°C).
• Plant 1 inch deep with 3-4 seeds per hill (small mounds of soil).
• Space hills 4-6 feet apart, with rows 6-8 feet apart for vine growth.

Indoor Sowing:

• Start seeds indoors 3-4 weeks before the last expected frost for an early start.
• Use biodegradable pots to minimize transplant shock.
• Transplant outdoors when seedlings have 2-3 true leaves and nighttime temperatures remain above 55°F (13°C).

Germination:

• Typically occurs within 7-14 days under optimal conditions.
• Keep soil consistently moist but avoid overwatering.

Care & Maintenance:

• Watering: Keep soil evenly moist; water deeply at the base to encourage strong roots.
• Fertilization: Apply a balanced fertilizer at planting and again when vines begin spreading.
• Mulching: Helps retain moisture and suppress weeds.
• Support: Can be grown on a sturdy trellis for space-saving or left to sprawl.
• Pest & Disease Control: Watch for squash bugs, vine borers, and powdery mildew; use row covers if needed.

Harvesting & Storage:

• Harvest when the pumpkin turns dark green to black and the rind is firm and hard.
• Cut with 2-3 inches of stem to improve storage life.
• Cure in a warm, dry place for 1-2 weeks before storing in a cool, dry location for several months.
