Water the spring onions regularly, ensuring that the soil remains consistently moist but not waterlogged. Apply organic fertilizers or balanced NPK (nitrogen, phosphorus, potassium) fertilizers as per the recommended dosage to promote healthy growth.
4. Pest and Disease Management
Monitor the crop for pests like onion thrips and onion maggots. Consider using organic pest control methods such as neem oil or insecticidal soap. Proper crop rotation and practicing good sanitation in the garden can help prevent the spread of diseases like onion white rot.

Spring onions can be harvested at various stages of growth. For green onions, harvest when the stems are around 15-20 centimeters tall. For bulb onions, wait until the bulbs reach a desirable size. Harvest by gently pulling out the plants from the soil.
Store spring onions in a cool, dry place or refrigerate them for a few days.
