Setup, Compatibility & Care
Sowing Seeds: Sow seeds indoors 6-8 weeks before the last frost or directly outdoors after the danger of frost has passed. Plant seeds about 1/4 inch deep in well-draining soil. For containers, use a good quality potting mix.
Spacing: If sowing directly, space seeds about 1/4 inch apart, thinning to 2-3 inches apart once seedlings are established. For mature bulbs, allow 3-4 inches between plants.
Sunlight: Plant in a location that receives full sun (6-8 hours per day).
Watering: Keep the soil consistently moist but not waterlogged. Water more frequently for plants in containers, as they dry out faster.
Soil: Prefers fertile, well-draining soil. Amend garden beds with compost before planting.
Compatibility: Compatible with most common garden vegetables. Can be grown alongside carrots, lettuce, and brassicas. Avoid planting near peas or beans.
Care: Once established, onions require minimal care. Monitor for pests like onion flies or thrips. Weeding is important, especially when plants are young, to reduce competition.
