Onions, essential for cooking, can be effortlessly grown in any garden. They don’t require much space or special tools. For successful home cultivation, just ensure good soil and follow some key steps.
Varieties of Onions: There are three main types – white, yellow, and red or purple, each with a unique flavor. White onions are sharp and tangy, yellow ones sweeter, and red onions fit both cooked and raw dishes. Your choice depends on taste and climate suitability; some types do better in certain temperatures. Short-day onions sprout in winter for warmer areas, while long-day onions in summer suit cooler regions.
Planting Methods: Choose between seeds or bulbs. Seeds start indoors then move outside, while bulbs, ideal for home gardens, are quicker and sturdier, available from nurseries, and take about four months to mature.
Site Selection: Onions thrive in nutrient-rich, peaty, well-drained soil, preferring organic compost over chemical fertilizers. Prepare the site a month ahead, ensuring it gets plenty of sun.
When to Plant: Plant in spring, late summer, or winter, depending on whether you use bulbs or seeds. Spring is best for bulbs, late summer for both, and winter for indoor starts. Plant during the waning moon for best results.
Planting Process: Prepare bulbs in moist soil two weeks before outdoor planting. Dig holes three times the bulb’s length, spacing plants 10-15 cm apart and rows 40 cm apart. Plant the bulbs and water them well.
Caring for Onions: Regular watering, disease and insect management (try companion planting with radishes or insecticidal soaps), and maintaining 15-25°C are key. Weed with hoeing and consider companion planting with carrots, strawberries, tomatoes, lettuce, cucumbers, and beets, but avoid peas and beans.
Harvesting: Onions are ready when tops yellow. Gently pull them out, dry for a day or two, then store in a dry, ventilated area. Harvest time varies by variety and method.
