planting onion seeds
Onions have a long growing season, so it is recommended to start your seeds indoors about 10-12 weeks before the last frost date in your region.
transplanting onion seedlings
Plant the seedlings with the base of the plant just below the surface of the soil. Space them 4 inches apart in staggered rows, so each bulb has room to fully develop.
Watering
Onions require consistent moisture, so water your plants regularly, providing about an inch of water per week.
Bolting
Bolting is often caused by water stress or growing the wrong day length variety for the location, so re-evaluate your watering schedule or choose a different variety for better results next time.
Harvesting
Harvest the bulbs by carefully lifting the soil under each one with a garden fork. Move indoors to fully cure by keeping them in a location with good air circulation and temperatures between 70 and 90°F for two to three weeks.
