How to Sow and Plant
+
Sow round white onion seeds indoors from July to September in warm, well-drained soil, ideally using peat pots for easy transplanting. Transplant seedlings outdoors from March to May when the risk of frost has passed. Space plants to allow their bright, round bulbs room to develop fully. For outdoor sowing, prepare soil by loosening it to ensure good drainage. Harvest begins in May and continues through September, depending on planting time. This method ensures both young, crisp onions for salads and mature bulbs rich in sweet, aromatic flavor.
Round white onions thrive in full sun with well-drained, fertile soil enriched with organic matter. Keep the soil consistently moist but avoid waterlogging to promote healthy bulb development. Regularly remove weeds to reduce competition and improve air circulation. Applying balanced fertilizer during the growing season supports vigorous growth and flavorful bulbs. Harvest young for a crisp, mild flavor or wait until fully mature to enjoy their sweet, aromatic richness. These onions benefit from a summer growing period with moderate watering and good airflow to prevent disease and enhance their distinctive taste.
For best results, start sowing these sweet round white onion seeds indoors from July to September, then transplant seedlings outdoors in early spring.
