Seedling
7-10 daysTwo cotyledons emerge, followed by true leaves; plants are small and delicate
Thin seedlings to proper spacing once they have 2-3 true leaves; keep soil moist; provide adequate light to prevent leggy growth
Vegetative
2-3 weeksRapid vine and leaf growth; plants develop thick stems and large lobed leaves; vines spread horizontally
Mulch around plants to retain moisture and keep fruit off soil; fertilize every 2-3 weeks; remove any diseased leaves; provide support or space for sprawling vines
Flowering
2-3 weeksLarge, bright yellow flowers appear; male flowers typically emerge first, followed by female flowers with small developing fruit behind the bloom
Ensure adequate bee activity for pollination; do not over-fertilize with nitrogen as it promotes foliage at expense of flowers; maintain consistent watering
Fruiting
2-4 weeksYoung squash rapidly enlarge behind the female flowers; skin color deepens to bright golden yellow; warty texture becomes more pronounced
Pick fruits when 6-8 inches long for best flavor and texture; frequent harvesting encourages continued production; check plants every 1-2 days during peak season; remove any diseased or deformed fruit
Maturation/Harvest
Continuous through summerFruit reaches full size and color; skin hardens if left unpicked; older fruit becomes tough and bitter
Harvest at the 6-8 inch stage for tender, flavorful squash; allow some fruit to fully mature if saving seeds; cut fruit from vine with sharp knife rather than pulling
