Germination & Seedling
2-3 weeksSeeds sprout and develop first true leaves. Cotyledons emerge within 7-10 days.
Keep soil warm (70-80°F) and consistently moist. Thin to strongest seedling per hill once true leaves appear. Protect from cold drafts if starting indoors.
Vegetative Growth
3-4 weeksVines grow vigorously with large lobed leaves and developing tendrils. No flowers yet.
Water deeply and consistently; mulch around base to retain moisture and regulate soil temperature. Watch for powdery mildew in crowded conditions. Fertilize with balanced fertilizer every 3 weeks.
Flowering
2-3 weeksLarge yellow flowers appear on the vine. Male flowers bloom first, followed by female flowers with small fruit behind the bloom.
Ensure adequate pollination by maintaining a healthy garden environment for bees. Reduce nitrogen fertilizer to encourage fruit set. Continue consistent watering.
Fruit Development
4-5 weeksSmall green fruits develop and enlarge gradually. Skin hardens and becomes pale green/cream colored.
Water consistently; irregular watering causes cracking and poor quality. Allow 2-3 fruits per plant for best size and quality. Mulch keeps fruits clean and prevents rot.
Maturity & Harvest
Ongoing until frostFruits reach 2-4 pounds with hard, pale green skin. Vines may slow production as weather cools.
Harvest when skin resists fingernail puncture and vine begins to decline. Leave 2-3 inches of stem attached. Store in cool (50-60°F), dark location for months.

Fun Facts
- 🌱 Snowmass was specifically bred at Colorado State University to excel in high-altitude, short-season mountain climates while maintaining excellent eating quality.
- 🌱 Unlike summer squash, winter squash like Snowmass develops a hard rind that cures and hardens after harvest, creating a natural preservative coating that allows storage for months without refrigeration.
- 🌱 The name 'Snowmass' references the Colorado ski resort near where this variety was developed, emphasizing its cold-climate heritage and reliability in northern gardens.
