Seedling
7-14 daysEmergence of cotyledons (seed leaves) followed by first true leaves with characteristic lobed shape
Keep soil consistently moist but not waterlogged. Provide bright light. Thin to strongest seedling once true leaves appear.
Vegetative
2-3 weeksRapid growth of large lobed leaves and development of sturdy main stem and lateral branches
Maintain consistent watering and fertilize every 2-3 weeks with balanced fertilizer or nitrogen-rich feed. Support vining varieties with trellising.
Flowering
1-2 weeks (overlaps with fruiting)Appearance of bright yellow male and female flowers; female flowers have a small bulge (immature fruit) behind the bloom
Ensure adequate pollination by allowing bee access or hand-pollinate if needed. Reduce nitrogen fertilizer to encourage fruit set rather than excess leaf growth.
Fruiting
3-4 weeks of peak productionRapid development of tender, green courgette fruits from pollinated female flowers, reaching 6-8 inches within days
Begin harvesting when fruit reaches 6-8 inches long. Regular harvesting promotes continued production. Watch for powdery mildew and ensure good air circulation.
Harvest & Peak Yield
4-8 weeksMature courgettes ready for picking; plant continues producing new flowers and fruits with consistent harvesting
Pick fruit every 2-3 days when small and tender. Leaving mature fruit on vine signals plant to stop producing. Maintain moisture and nutrients for sustained yield.

Harvest Tips
Pick courgettes when 6-8 inches long and skin is tender for best flavor and texture. Harvest every 2-3 days; larger fruits become seedy and watery. Cut with a sharp knife or pruner close to the stem. Early morning harvesting yields the crispest fruit. Continue picking to encourage continued flowering and production.
