Mercury Cucumber is a hybrid, thin-skinned cucumber that is gynoecious and parthenocarpic. Being of a gynoecious variety, the Mercury only produces female flowers. Because the fruits originate from the female flowers, the yield is very high. Parthenocarpic varieties don’t require pollination from male flowers to produce fruit, making them easy to grow almost anywhere and resulting in seedless fruit! The combination of these two traits makes this variety super productive and great for any level grower.

Mercury Cucumber can be grown in a greenhouse but is ideal for outdoor production. Fruits have thin skins and don’t need to be peeled. They are shiny, dark green, and usually average 8″ long when allowed to reach a larger size. Fruits have a small seed cavity and small seeds. Mercury can be used as a pickling variety when harvested small or can be used as a slicer when allowed to get larger.

Cucumbers perform best when direct-seeded. They do not perform as 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 given 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 harvesting and processing. It will also help to prevent fruit discoloration or yellowing from sitting on the soil surface. Our Hortonova Trellis Netting works great for trellising cucumbers and is easy to install.

    Out of 60 seeds planted we have had 3 cucumber plants come up. Still not sure they will make it. Very disappointed. Planted the Lea seeds as well and no luck with them. We were planting for the fall but oh well. Hopefully we will have better luck with the okra and carrots at a later date.

    Planted Mercury, National Pickling, and Dar cucumbers on same day. Mercury had 100% germination rate and were the first to pop the soil. Time will tell how well they grow and taste for us, but I’m happy to report we’ve had no germination issues with these seeds.

    Soaked seeds over night, planted the next day. Two days later, they all popped. 5 out of 5 they all look good, can’t wait!
