Ishikura Long White is a type of bunching onion intended for all-season cultivation in both open and protected ground. The plant features robust growth, reaching a height of 70-80 cm, forming a long and juicy stem with a delicate and zesty taste. The leaves are long, upright, fiberless, ensuring ease of use and good storage at room and reduced temperatures. The leaf coloration varies from medium to dark green, while the taste is characterized by medium spiciness, making this onion versatile for various culinary purposes.
The maturity period of the variety is mid-early — about 60 days, although some sources indicate a vegetation period of up to 160-200 days, which may depend on growing conditions. Ishikura Long White onion is characterized by high yield and disease resistance, particularly to powdery mildew, ensuring a stable and quality harvest. Thanks to these characteristics, the variety is suitable for both amateur and professional cultivation.
For successful cultivation, it is recommended to apply fertilizer to the soil before sowing and observe crop rotation, as prolonged growing in one place may lead to plant weakening. Seeds can be sown either in a seedbed or directly into a permanent spot. The onion is ready for harvesting when the foliage reaches a height of 20-30 cm. This variety is valued for its durability, good storability, and excellent taste qualities, making it an excellent choice for gardeners and lovers of fresh greens.
