I’m growing several types of cucumber this year, and one of them is a Japanese cucumber called ‘Nippon Sanjaku Kiuri.’ I got it from the Seed Savers Exchange catalog, and apparently the name translates to “Japan Three Foot Long Cucumber,” although according to the seed packet instructions, they’re best harvested at about a foot and a half. It also suggests that you use a trellis if you want them to grow straight, otherwise the cucumber forms a coil.
I was running out of trellis materials, so these plants are being supported with wire shelves I had available. I keep arranging the shelving to support the cucumbers as they appear, and it does help them grow straighter. The cucumber below is over a foot long!
