5. Watering:

Keep the soil consistently moist but not waterlogged. Onions need regular, even watering. Be mindful not to let the soil dry out completely, especially during hot weather.
6. Sunlight:

Place the container in a sunny location that receives at least 6-8 hours of direct sunlight daily. Onions require plenty of sunlight to grow bulbs.
7. Fertilizing:

Use a balanced, all-purpose fertilizer or one specifically formulated for root crops. Apply fertilizer according to the package instructions, typically every 3-4 weeks.
8. Thinning:

As your onions grow, you may need to thin them to ensure they have enough space to develop properly. Thin to a spacing of 4-6 inches between each plant.
9. Maintenance:

Keep an eye out for pests and diseases, and address any issues promptly. Onions are relatively low-maintenance, but they can be susceptible to pests like onion flies and diseases like onion rot.
