Other Common Names: Yamato Sanjaku, Yamato Extra Long, or Japanese Cucumber

How to Grow Yamato Sanjaku

Sow seeds in the late spring or early summer after the last frost in a warm, sunny location. To get a head start, seed indoors 2-3 weeks prior to the last frost and transplant when the weather warms. Keep the soil moist. Fertilize as needed. We recommend training it to climb a vertical support for better air circulation, straighter fruits, and an easy harvest. Allow the soil to dry between waterings occasionally to combat pests and diseases. It has a monecious flowering habit (the plant produces both male and female flowers).

Harvesting Yamato Sanjaku Cucumber

Harvest when the fruit is 18-30 inches long, deep green, and firm. Gently snip off the fruit at the base of the stem.

Culinary Tips

This variety is the most traditional to be used in sushi bars. Its small seeds and long shape are perfect for rolling into your favorite sushi. These are also ideal for thinly slicing and pickling into sumonomo. Snacking on them fresh is also a must-try!

Tips From Our Gardeners

“While trellises are undeniably practical when it comes to growing cucumbers, I recommend training this particular variety to grow on a trellis to allow full appreciation of the attractive, long, and slender fruits.”
