Calypso Cucumber is a hybrid, high-yielding pickle cucumber variety. In research trials, Calypso produced earlier and had higher yields than other pickling varieties. It has a very strong disease package that includes resistance to mildews and cucumber mosaic virus. Plants produce firm, uniform fruits that are green with white spines. Fruits average 1" in diameter and are best harvested at 4-5" long. This is a great variety for making cucumber salads or fresh vegetable trays, but it is known for the high-quality pickles that can be made with them. Slice them to make traditional hamburger chip pickles, or quarter them to make delicious pickle spears that fit perfectly into a jar.

Calypso Cucumber is a gynoecious variety, meaning it produces only female flowers. Because the fruits originate from the female flowers, the yield is very high. Each packet of seeds contains 10-20% seeds of a pollinator variety that is similar in shape and size to Calypso. The pollinator is an open-pollinated variety that provides the male flowers needed for pollination. As a result, we recommend planting the entire seed packet to ensure the male flowers are present for pollination.

Cucumbers perform best when direct-seeded. They do not perform well when transplanted. Cucumbers may be direct-seeded by hand or with a walk-behind seeder. To obtain a good stand of plants, we suggest planting seeds every 6-8" inches and thinning to one seed per foot. Cucumbers are a vining plant and grow best when provided a trellised structure to climb. Use a strong trellis that is well-supported with deeply driven stakes. Keeping plants off the ground will reduce the potential of plant diseases like mildews and other diseases that can result from excess plant moisture. Trellising will also keep the fruits cleaner and save time with harvest and processing, in addition to reducing fruit discoloration or yellowing from sitting on the soil surface.
