Shintokiwa Long-Fruited Cucumber - Biodynamically Grown and Organic

seeds
Cucumis sativus
(62 days) Open pollinated.

Productive smooth-skinned long slender cucumber first surfaced in the Turtle Tree catalog and highly recommended by our trialers. Combining looks, health and flavor, rated as superior to the Suhyo cultivars with better uniformity, fewer defective bottoms and more resistance to BW. 

The fruits, averaging 9–10" and growing up to an edible size of 12" in good fertility, are sweet, crisp and juicy without bitterness. One trial taster described their flavor as “flowery, buttery and delicious.” Bob of Wasserman Family Farm in Corrales, NM, reports that they have a faithful following at the growers’ market—even among little kids. 

Customer Robert U. wrote to us in 2024: “I live in Idaho where we get quite a mixture of very hot (100˚+) in the summer and cool days heading into the fall, and this cultivar remains productive throughout.”

Additional Information

Long-fruited Types

Asian cukes are more resistant to CMV than other types.

For really straight fruit, consider trellising your cukes. Adam Tomash and June Zellers grow theirs on a 5' arch made from cattle panel, a welded wire material with big holes. They explain this trellis system in an article in the MOF&G winter 2008-9 edition.

Cucumbers

  • About 30-50 seeds/g; variations noted.
  • Days to maturity are from seeding date. From transplant, subtract 20 days.

Culture: May be started indoors for early production, or direct-seeded when soil has warmed. Minimum germination soil temperature 65°, optimal range 65–95°. Very tender, will not survive frost. Direct seed 3" apart thinning to 1' apart in rows 4–6' apart or 6 per mound in hills 4' apart thinning to 3 best plants. For transplants: once seedlings have 1–2 true leaves, about 3 weeks old, plant 1' apart in rows 4–6' apart. Cucumbers require good fertility and regular rain or irrigation for abundant yields. Without adequate water, fruits will be misshapen and bitter. Pick cukes frequently for best production, or else the plants shut down. Make sure to remove blimps to the compost pile.

Combat striped cucumber beetles by handpicking early AM when the dew makes them sluggish, or use floating row covers, removing when cukes flower. Cucumber beetles are the vector for BW.

Using compost in conjunction with row covers (rather than either alone) increased cucumber yields at the University of Michigan.

Parthenocarpic varieties can set fruit without being pollinated, an advantage in cold cloudy summers. Gynoecious varieties produce almost exclusively female flowers for uniformity and high yields.

Saving Seed: Saving cucumber seed is easy! Take that big yellow cuke that got away and save it for seed. Scoop out the guts of overripe fruit and ferment it in an uncovered container for a few days. A moldy gross cap to the slurry means the seeds are ready to rinse and dry. To ensure true-to-type seed, grow only one open-pollinated variety per season.

Diseases:

  • ALS: Alternaria Leaf Spot
  • ANTH: Anthracnose
  • BW: Bacterial Wilt
  • CMV: Cucumber Mosaic Virus
  • CVYV: Cucumber Vein Yellow Virus
  • DM: Downy Mildew
  • PM: Powdery Mildew
  • PRSV: Papaya Ring Spot Virus
  • R: Rust
  • WMV: Watermelon Mosaic Virus
  • ZYMV: Zucchini Yellows Mosaic Virus

Pest: Striped Cucumber Beetle
Cultural controls: use tolerant or resistant varieties, rotate crops, till under crop debris soon after harvest, use floating row covers until flowers appear, use plastic mulch, perimeter trap cropping (Black Zucchini and Blue Hubbard make particularly good trap crops), use yellow sticky strips, hand-pick early morning when beetles are very sluggish.
Materials: Surround, Pyrethrum (PyGanic).
