Onion Japanese Senshyu Yellow Seeds

Onion Japanese Senshyu Yellow is a classic overwintering variety. 

 

Valued for its strong growth, firm bulbs and dependable performance in cooler climates. It produces rounded golden onions with a mild flavour that suits everyday cooking, salads and gentle sautéing.

 

This traditional Japanese strain is known for its resilience through winter, forming sturdy plants that establish well in autumn and surge into growth as temperatures rise. The bulbs mature earlier than spring sown varieties, giving gardeners a welcome early season harvest.

 

Plants develop upright green foliage and uniform bulbs with tight skins that store well for several weeks. The flavour is smooth and balanced, making it a versatile choice for the kitchen and a reliable favourite for home growers.

 

Japanese Senshyu Yellow thrives in fertile well drained soil and benefits from a sunny open position. It is ideal for autumn sowing and performs well in beds, raised plots and vegetable gardens where early cropping is desired.

 

Sowing Instructions

Sow seeds thinly in trays or modules filled with moist free draining compost. Cover lightly with a fine layer of soil and maintain gentle warmth until germination. Transplant young seedlings into their final position once they are large enough to handle, spacing them to allow good air flow. Water well after planting and keep the soil lightly moist during establishment.

 

Grow and Maintenance

Keep the area free of weeds and water during dry spells to support steady growth. Avoid heavy feeding as onions prefer moderate fertility. Allow the bulbs to swell naturally in spring and early summer. When the foliage begins to bend and dry, lift the bulbs and allow them to cure in a warm airy place before storing. Rotate crops yearly to maintain healthy soil.
