Seedling
2-3 weeksCotyledons emerge, followed by true leaves with characteristic lobing. Plants are tender and compact.
Start seeds indoors 2-3 weeks before last frost or direct sow after soil reaches 65°F. Thin to strongest seedlings. Protect from slugs and cutworms.
Vegetative/Vine Growth
4-6 weeksVigorous vining growth with large palmately-lobed leaves. Plants spread rapidly along the ground or trellis, producing tendrils.
Provide ample space for sprawling vines or train to vertical support with slings for fruits. Fertilize every 3-4 weeks with balanced fertilizer. Mulch to retain moisture and suppress weeds.
Flowering
2-3 weeksLarge, bright yellow trumpet-shaped flowers appear singly or in clusters. Male flowers bloom first, followed by female flowers with visible ovary at the base.
Ensure adequate pollination by attracting bees with flowers or hand-pollinating with a small brush. Reduce nitrogen to encourage flowering. Keep soil consistently moist.
Fruit Development
4-6 weeksYoung fruit appears pale green, gradually turning distinctive creamy white. Fruits grow to 2-4 pounds, developing smooth skin and compact, squat shape.
Thin to 2-3 fruits per plant to encourage larger, quality pumpkins. Place straw under developing fruit to prevent rot. Continue regular watering and monitor for pests and diseases.
Maturity/Harvest
1-2 weeksSkin hardens and fully develops the characteristic milky white color with slight ribbing. Stem becomes woody and brown. Field curing deepens flavor and hardens skin for storage.
Leave on vine until vine dies back naturally or first hard frost threatens. Harvest with 3-4 inches of stem attached. Cure in warm, dry location for 10-14 days before storage.

Harvest Tips
Harvest when skin is fully white and unblemished, typically in mid to late fall before the first hard freeze. Cut (don't pull) pumpkins from the vine, leaving 3-4 inches of stem attached to prevent rot. Test ripeness by pressing thumbnail against skin—it should be hard to penetrate. Cure harvested pumpkins in a warm (70-80°F), dry, well-ventilated location for 10-14 days to harden skin and seal cuts. Store in a cool (50-60°F), dry place with good air circulation; properly cured Lumina pumpkins can store 2-3 months.
