Onions are one of the most widely grown vegetables in the world and an essential ingredient in countless recipes. Growing onions from seed provides gardeners with access to a wide range of varieties while reducing gardening costs and allowing complete control over the growing process.
Popular onion varieties include Yellow Sweet Spanish, Red Burgundy, White Lisbon, Walla Walla, and various storage onions. Some onions are best suited for fresh use, while others can be stored for several months after harvest.
Onion seeds should be started indoors 8 to 10 weeks before the last expected frost or sown directly into the garden in suitable climates. Plant seeds approximately ¼ inch deep in fertile, well-drained soil enriched with compost.
Onions require full sunlight and consistent watering during their early growth stages. Proper spacing allows bulbs to develop fully and improves airflow around the plants. Balanced fertilisation supports healthy leaf development, which directly influences bulb size.
Onions are rich in vitamin C, vitamin B6, potassium, antioxidants, and sulphur compounds that contribute to heart health and overall wellness. They are widely used in soups, curries, stir-fries, salads, sauces, and roasted vegetable dishes.
Harvest onions when the green tops naturally fall over and begin to dry. Allow harvested bulbs to cure in a warm, well-ventilated area before storing them for long-term use.
Growing onions from seed is both economical and rewarding, providing gardeners with fresh, flavourful bulbs that can be enjoyed throughout the year.
