2. Preparing the Container
- Size and Depth: Choose a container that is at least 6 inches deep and wide enough to accommodate several plants. Spring onions don’t need a lot of space, but they do require adequate room for their roots to grow.
- Drainage: Ensure the container has good drainage holes at the bottom to prevent waterlogging, which can lead to root rot. You can add a layer of gravel or small stones at the bottom to enhance drainage.
3. Planting Spring Onions
- Soil: Use a well-draining, fertile potting mix. You can enhance the soil with organic compost to provide extra nutrients.
- Sowing Seeds: Sow the spring onion seeds about 1/2 inch deep and 1 inch apart. Cover them lightly with soil and water gently.
- Spacing: If using seedlings, plant them about 1 inch apart. Ensure each plant has enough space to grow without overcrowding.

4. Watering and Care
- Watering: Keep the soil consistently moist but not waterlogged. Water the plants regularly, especially during dry periods.
- Fertilizing: Feed the spring onions with a balanced liquid fertilizer every 2-3 weeks to promote healthy growth.
- Sunlight: Place the container in a location that receives at least 6 hours of sunlight daily. Spring onions thrive in full sun but can tolerate partial shade.
5. Harvesting
- Timing: Spring onions are usually ready to harvest in 8-10 weeks. You can start harvesting when the plants reach a height of about 8 inches.
- Method: Use a sharp knife or scissors to cut the onions just above the soil level. This allows the plant to regrow for another harvest.
