Choosing the Right Variety
When it comes to spring onions, there are several varieties suitable for the UK climate. Here are some popular choices:

Sowing and Planting
Spring onions are typically grown from seeds. Follow these steps to sow and plant your spring onions:
- Sowing method: Directly sow spring onion seeds in the garden from early spring to late summer. Plant them about 1/2 inch deep and space them 1-2 inches apart in rows that are 6-8 inches apart.
- Soil conditions: Spring onions prefer well-drained soil that is rich in organic matter. Prepare the soil by incorporating compost or well-rotted manure.
- Succession planting: To enjoy a continuous harvest, sow seeds in batches every few weeks.
- Thinning seedlings: When the seedlings have developed their first true leaves, thin them out to allow proper spacing. Leave the strongest seedlings spaced about 3-4 inches apart.
Growing
To ensure healthy growth and a bountiful harvest of spring onions, consider the following tips:
- Sunlight: Spring onions prefer full sun but can tolerate partial shade. Aim to provide them with at least 6 hours of direct sunlight each day.
- Watering: Keep the soil consistently moist, especially during dry spells. Spring onions require regular watering to promote bulb development.
- Soil conditions: Spring onions prefer well-drained soil that is rich in organic matter. Mulching around the plants can help retain soil moisture and suppress weeds.
- Fertilizing: Apply a balanced fertilizer or side-dress with compost or well-rotted manure during the growing season to provide additional nutrients.
- Pest control: Monitor your spring onion plants for common pests such as onion flies or thrips. Use organic or chemical controls as necessary.
- Harvesting: Spring onions can be harvested when the stems have reached a desirable size, typically about 8-12 inches in length. Gently pull the onions out of the ground, or cut them just above the soil level.
