| Product Care Instructions | Onions are a staple crop for any home gardener and one of the most rewarding vegetables to grow from seed. Whether in large garden beds or patio containers, they thrive with just a little care. From sweet and red onions to spring onions and shallots, each type adds its own unique flavour to the kitchen. Start seeds indoors early for a strong head start and choose a sunny, well-drained spot for planting. Keep soil moist but not waterlogged for the best growth. Indoor Sowing Fill a half seed tray with fine-textured seed compost and lightly scatter seeds across the surface without overcrowding. Cover lightly and keep moist. A heated propagator or heat mat provides consistent warmth, encouraging quick germination and strong root growth. Planting Out Transplant Professional Grower Plugs 1cm deep, spacing 10cm between plants and 30cm between rows. Rotate crops each season to avoid soil-borne pests and diseases, and avoid planting onions or related crops (leeks, garlic, shallots) in the same spot more than once every 3–4 years. Interplanting Onions store well, so one sowing is usually enough. Use the spaces between rows to grow carrots, cabbages, or lettuce. Their strong scent naturally deters pests like carrot flies and aphids. Companion herbs such as mint and parsley also help keep onion flies away. |
