About Japanese Suyo Long Cucumber
This heirloom Japanese variety produces long, slender cucumbers with a delightfully mild and sweet flavour. The skin is thin and tender, making peeling unnecessary. Plants are vigorous and productive, especially when trellised, which encourages straighter fruit and improves air circulation. Great for fresh eating, slicing, and pickling, the Japanese Suyo Long is a favourite among home gardeners looking for both performance and flavour.

Where Can You Grow Japanese Suyo Long Cucumber?
This variety prefers full sun and rich, well-draining soil. Ideal for gardens, raised beds, and greenhouses in Zones 3–9, though it benefits from added warmth in cooler zones. Trellising improves yield and ease of harvest.

History and Historical Uses
The Suyo Long cucumber has long been grown in Japan, valued for its mild flavour and long, graceful shape. Its popularity has spread globally due to its superior eating qualities and reliable productivity in both traditional and modern gardens.
