Imai Early Yellow Onion Seeds | Intermediate-Day Bulbing Onion

Mild Yellow Onions for the Home Garden

Imai Early Yellow onion (Allium cepa) is an intermediate-day bulbing onion with yellow skins and a mild, crisp texture. Grow it in a sunny vegetable bed or raised bed, then bring your harvest into the kitchen for slicing, sautéing, and everyday cooking.

Starting from seed lets you plan a small kitchen patch or a larger planting. Keep the bed weeded and evenly watered as the seedlings develop into bulbs; their final size and harvest timing depend on your location, planting date, and growing conditions.

Choose Planting Dates for Your Location

Onion bulbing responds to day length, so match this intermediate-day variety to your latitude and local planting calendar. Winter hardiness zones alone do not determine whether an onion will bulb well in your garden.

Fall sowing and overwintering may be suitable where local winter conditions allow. In colder areas, follow local guidance for indoor starting and spring transplanting rather than relying on a fixed January transplant date. Harvest timing varies; a short seed-to-bulb maturity period is not guaranteed.

Sowing and Growing

• Use fertile, well-drained soil in a sunny location.
• Start seeds in a fine seed-starting medium or sow into a well-prepared bed when locally appropriate. Follow packet directions for sowing depth and spacing.
• Keep the growing medium evenly moist during germination, without waterlogging.
• Harden off indoor-grown seedlings gradually before transplanting.
• Space plants to allow bulbs to develop, following the packet's recommendations.
• Weed carefully and water consistently during active growth. Do not rely on drought tolerance for a good bulb crop.
• Fertilize according to soil needs and local onion-growing recommendations.

Harvesting and Curing

For mature bulbs, watch for developed skins and tops that naturally yellow and fall over. Lift carefully, avoiding bruising, and cure in a dry, shaded, well-ventilated location protected from rain. Curing time depends on humidity and airflow; allow necks and outer skins to dry thoroughly before trimming and storing.

Store sound, cured bulbs in a cool, dry, ventilated place. Use damaged or thick-necked bulbs first, and check stored onions regularly. Storage life varies with growing and curing conditions.
