FAQs

When is the best time to sow White Lisbon spring onion seeds?

You can sow outdoors from March to August for a continuous harvest. For very early crops, sow in September and overwinter. Successive sowings every few weeks during the main season will ensure a steady supply.

What kind of soil do White Lisbon spring onions need?

They prefer fertile soil that is moist but well-drained. Amending the soil with compost or a balanced fertilizer before sowing is recommended.

How much sun do these spring onions require?

White Lisbon spring onions thrive in full sun, which promotes optimal growth and flavor development.

Can I grow these in containers?

Yes, they are suitable for container gardening as long as the containers are deep enough to accommodate root growth and have adequate drainage holes.

How do I keep the soil consistently moist without causing rot?

Water regularly, especially during dry periods, but ensure that excess water can drain away freely. Avoid letting the soil become waterlogged. Mulching can help retain moisture.

What is the difference in taste between young and mature White Lisbon spring onions?

When young, they have a mild, fresh flavor perfect for salads. As the stems mature and start to bulb, the taste becomes more pronounced and pungent, suitable for cooking.

Can White Lisbon spring onions be grown alongside other vegetables?

Yes, their rapid growth makes them ideal for intercropping with slower-growing vegetables, helping to maximize garden space and utilize the soil efficiently.

Troubleshooting

Seeds not germinating

Ensure soil is kept consistently moist after sowing and is at a suitable temperature. Check seed depth; sowing too deep can hinder germination.

Plants bolting (going to seed prematurely)

This is often caused by stress from irregular watering or temperature fluctuations. Ensure consistent moisture and a suitable planting time.

Yellowing leaves

Can indicate a lack of nutrients or overwatering. Check soil moisture and consider a light feed with a balanced liquid fertilizer if necessary.

Pest infestation (e.g., aphids)

Wipe off pests with a damp cloth or spray with insecticidal soap. Encourage beneficial insects like ladybugs.
