Highlights

  • High-yielding 'Ruby Red' onions—pick young as mild spring onions or grow to full-size bulbs with a sweet, mild flavour.
  • Easy-care variety suited to full sun and loose, free-draining soil (pH 6.0–7.0); sow indoors in February–March and transplant when ready.
  • Good disease resistance; practice crop rotation and interplant with carrots, cabbage, lettuce or herbs like mint and parsley to discourage pests.

Description

Marshalls Garden Onion Seeds 'Ruby Red' produce versatile, sweet-flavoured onions that can be harvested early as spring onions or left to mature into full-size bulbs. Sow indoors in February–March on fine seed compost, keep moist, then transplant plugs 1cm deep with 10cm between plants and 30cm between rows. Prefers full sun, loose free-draining soil rich in organic matter (pH 6.0–7.0). Expected plant height around 40cm, with green, white and purple colouring; main harvest and blooming period in August–September. Rotate crops every 3–4 years and interplant to help deter pests; one sowing usually supplies a season’s harvest.

Product Care InstructionsIndoor 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.
