Cucumis sativus. Exceptionally sweet, tender, and above all -- hardy. Known in the southern islands of Japan, the seeds have been preserved over generations by an old family in Beppu City on Kyushu Island. The long, slender 8-inch fruit is bitter free and super sweet with inconspicuous seeds, making it a perfect marketing cucumber with flavor that stands out from the rest! The 1939 seed catalog of Tanaka & Co. said: “Hardiness and prolific bearing character are meritorious features of Japanese varieties of cucumber. They withstand drought, moisture and attack of fungoid disease to a remarkable degree.”[1]

- Additional instructions: Cucumber roots are sensitive to disturbance, transplant carefully.
- Fruits are medium green with small, white "spines" can be harvested from 1½"–6" long. Resistant to anthracnose, angular leaf spot, cucumber mosaic virus, downy mildew, and powdery mildew. Apply a slow-release, balanced fertilizer (equal parts nitrogen, phosphorus, and potassium) to soil before sowing. Since root system is extensive, fertilize the entire growing area evenly, as cucumber root are susceptible to fertilizer burn when fertilizer is applied too densely around the base of the plant.[2]
- Cucumbers require rich, well-drained soil, a long rotation cycle (don't plant them in the same spot year after year), consistent moisture and proper spacing help reduce stress on plants and avoidance of common cucumber diseases like scab and mosaic.
- Most varieties of cucumber vines spread from row to row. Training on a cage, trellis or fence along the edge of the garden will correct this and also lift the fruit off the soil. Trellising gets leaves up off the ground so that they dry off faster. Also, if the vines are trellised, the gardener is less likely to step on the vines and there is no need to move the vines for weeding or other purposes, reducing the risk of damage. If trellising is not possible, there are many excellent bush varieties of cucumber available now. Most of them produce well for a limited amount of space and may be a desirable alternative in a small garden. If vines are not trellised, avoid destroying blossoms or kinking vines by gently rolling the vines away rather than lifting them when searching for harvestable fruit. In non-trellised plantings, organic materials are useful in the summer to return moisture and keep the fruit clean. Working in the vines when leaves are wet could spread disease. Wait until after morning dew or rain evaporates. There has been a significant increase in disease resistance in cucumber varieties in recent years. Select resistant varieties when possible[3]
- Harvesting instructions: Pick, and pick some more! Overly mature cucumbers on the vine will slow production of new cucumbers. Cut the stem rather than pulling at the fruit, as stems are fragile. To increase the quality and storage time, once picked, immediately immerse in cold water to disperse “field heat”. Harvest at 8". Harvest frequently to maintain production.
