Are you looking for a low-maintenance, flavorful addition to your garden? Look no further than Welsh onions, also known as spring onions or scallions. These versatile alliums are a delight to grow, offering a mild onion flavor with a touch of sweetness. Learning how to plant Welsh onions is a simple process that can reward you with fresh, homegrown flavor all season long.
Understanding Welsh Onions
Welsh onions are a perennial variety of Allium fistulosum, meaning they come back year after year. Unlike their bulb-forming cousins, Welsh onions don’t develop a true bulb. Instead, they produce a cluster of edible, elongated stalks that are harvested for their flavorful green leaves and white bases.
Choosing the Right Location
Welsh onions thrive in a sunny location with well-drained soil. They prefer a soil pH between 6.0 and 7.0, which can be adjusted with lime if needed. Choose a spot that receives at least six hours of sunlight daily for optimal growth.
Preparing the Soil
Before planting, prepare your soil by loosening it with a garden fork or cultivator. This will improve drainage and allow roots to spread easily. Incorporate a layer of compost or aged manure to enrich the soil and provide essential nutrients.
Planting Welsh Onions
Welsh onions can be planted from seed or purchased as transplants.
From Seed:
- Timing: Sow seeds directly outdoors after the last frost has passed, typically in early spring.
- Spacing: Space seeds 1/2 inch apart and 12 inches between rows.
- Depth: Sow seeds 1/4 inch deep.
- Watering: Keep the soil consistently moist until germination occurs.
From Transplants:
- Timing: Transplant seedlings outdoors in the spring or fall.
- Spacing: Space plants 6 to 8 inches apart in rows 12 inches apart.
- Depth: Plant transplants at the same depth they were growing in their containers.
- Watering: Water thoroughly after planting.
Caring for Welsh Onions
Once established, Welsh onions are relatively low-maintenance.
Watering: Water regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
Fertilizing: Apply a balanced fertilizer every few weeks, especially during the growing season.
Weeding: Keep the area around your Welsh onions weed-free to prevent competition for nutrients and water.
Pest and Disease Control: Welsh onions are generally resistant to pests and diseases. However, keep an eye out for onion flies, aphids, and fungal diseases.
Harvesting Welsh Onions
The beauty of Welsh onions is their continuous harvest. You can start harvesting individual stalks as soon as they reach a usable size, typically around 6 to 8 inches tall.
Harvesting Tips:
- Cut the stalks: Use a sharp knife or scissors to cut the stalks at ground level.
- Harvest selectively: Harvest only the stalks you need, leaving the rest to continue growing.
- Harvest throughout the season: You can harvest Welsh onions throughout the growing season, from spring to fall.
Winter Care and Overwintering
Welsh onions are hardy and can survive mild winters. However, in colder climates, they may require some protection.
Winter Care:
- Mulching: Apply a layer of mulch around the plants to insulate the roots from frost.
- Protection: In extremely cold areas, consider covering the plants with burlap or frost blankets.

Prepare for Winter:
- Cut back: In late fall, cut back the foliage to about 2 inches above the ground.
