Sowing indoors: Sow seeds 6 - 8 weeks before planting out date. Apply Sea Magic from first watering. From second set of true leaves to time of transplanting, alternate between Sea Magic and seed-starting fertilizer (such as Evolve) once per week.
Planting Depth: 1/4".
Seed Spacing: Space seeds 1/2” apart and then thin to 2” to 3” apart.
Planting Out: Plant in well-drained fertile soil once seedlings are established and risk of frost has passed or earlier if the seedlings have been sufficiently hardened off. Harden off by gradually setting seedlings outside for a couple of hours in a protected spot the first day and then increasing the time and exposure to elements each day thereafter. By ten days, you should have worked up to leaving them outside over night as long as the temperatures are higher than 10º C. The optimal growing temperature for onions is 13º to 25º C. Onions require lots of light to grow well, so locate in the sunniest areas of the garden. Onions require fertile soil so be sure to work in plenty of quality compost, such as Sea Soil, before planting or direct-seeding.
Plant Spacing: Space transplants 2” - 2” apart; spacing will significantly impact the size of the onion bulbs.
Outdoors: Direct seed as soon as ground can easily be worked. Space seeds 1/2” apart and then thin to 2 to 2” apart. Plant in rows 5” - 10” apart.
Harvesting: Cut stalks when plants reach 14 - 18 inches.
Growing in Containers: Ideal for containers 8 inches and up.
Fertilizing (Containers): Plant in a quality, organic based potting mix with good drainage.
Watering (Containers): Water containers deeply when top inch feels dry to the touch. Monitor every day or two during very hot weather.
Growing in Mixed Planters: This variety is well-suited for larger mixed planters such as half barrels.
Fertilizing (Garden): Plant in a garden recently amended with compost. Application of Sea Magic kelp supplement is beneficial.
