How to Grow

🌞 Choosing a Location

To thrive, White Lisbon bunching onions need full sun, requiring 6-8 hours of sunlight daily. They flourish best in temperatures ranging from 15°C to 24°C (60°F to 75°F), so pick a spot that meets these conditions.

🌱 Soil Preparation

These onions prefer well-drained, fertile soil with a pH between 6.0 and 7.0. Before planting, enrich your soil with compost or well-rotted manure to ensure optimal growth.

🌾 Planting Techniques

When planting, sow seeds at a depth of 1/4 inch and space them 6-12 inches apart. The best time to plant is either early spring or late summer for a fall harvest.
