5. Proper Thinning:

Once the seedlings are a few inches tall, thin them so that they are spaced approximately 4 to 6 inches apart. This prevents overcrowding and allows the onions to develop fully.

6. Watering:

Onions have shallow root systems, making them susceptible to drought. Water them regularly, ensuring the soil remains moist but not waterlogged. Overwatering can lead to bulb rot.

7. Fertilizing:

Fertilize the onions every few weeks with a balanced fertilizer to promote healthy growth. Avoid high-nitrogen fertilizers as they can lead to lush foliage at the expense of bulb development.

8. Weed Control:

Keep the onion bed free of weeds. Weeds compete with onions for nutrients and water, which can hinder growth. Hand-pulling or hoeing are effective ways to manage weeds without damaging the onion plants.
