Sprouting
1-2 weeksSmall green shoots emerge from the onion set; initial root development begins
Ensure consistent moisture and full sun exposure. Remove any loose papery skin from sets before planting.
Vegetative Growth
6-8 weeksFoliage develops; plant produces multiple green leaves and begins underground bulb formation
Maintain consistent watering and fertilize with balanced fertilizer every 3-4 weeks. Thin seedlings or sets to proper spacing. Keep weeds controlled.
Bulbing

Maturation
2-3 weeksBulb reaches full size; foliage begins to yellow and lodge (fall over naturally)
Reduce watering to stress the plant and encourage bulb hardening. Stop fertilizing. When 75% of tops have fallen, prepare for harvest.
Harvest & Curing
