Planting Onions Tricolor Colleaction

Planting and care instructions

For best results, plant this category at the recommended depth and grow it in a suitable location.

• Planting: Plant in spring or autumn in fertile, well-drained soil. Set the onion sets 2–3 cm deep and 5–10 cm apart, with the tip just above the soil.
• Light & location: Grow in full sun.
• Watering: Water after planting and keep the soil lightly moist, but avoid waterlogging.
• After flowering: Harvest when the tops yellow and fall over, then dry the bulbs in an airy place before storage.
• Feeding & care: Feed lightly early in growth; avoid high-nitrogen fertilizer once the bulbs begin to swell.
• Useful tip: Keep the bed weed-free and reduce watering as the bulbs mature to help them ripen well.
