Mercury Cucumber is a hybrid, thin-skinned cucumber that is gynoecious and parthenocarpic. Gynoecious cucumbers produce only female flowers, which results in larger harvests since the fruit originates from the female flower. Parthenocarpic varieties don’t require pollination to produce fruit, making them easy to grow almost anywhere! 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.
