Maximize your garden's potential with high-quality Spacemaster 80 Cucumber seeds. If you have a small backyard, a balcony, or just a few patio pots, this is the cucumber you’ve been waiting for. Developed by Cornell University, the Spacemaster 80 is an improved version of the original "space-saving" classic, bred specifically to provide full-sized, delicious cucumbers on compact, 2-to-3-foot vines. At The Seed Guy®, we recommend this variety for urban gardeners and homesteaders alike who want to reclaim their garden space without sacrificing the crunch of a fresh-picked slicer.
In the garden, Spacemaster 80 is a sturdy, bush-type performer that resists many common garden diseases, including scab and mosaic virus. While the plant stays small, the fruit is impressively large—producing smooth, dark green cucumbers that reach 7 to 8 inches in length. They are never bitter and have a refreshing, crisp texture that is perfect for summer salads, sandwiches, or even quick refrigerator pickles. At The Seed Guy®, our seeds are tested for elite germination and vigor, ensuring that even in a small container, you can harvest a mountain of garden-fresh cucumbers all summer long.

Spacemaster 80 Cucumber Planting Instructions:
1. When to Plant: Cucumbers love the heat. Sow seeds directly into the garden or large containers once the soil temperature has reached at least 70°F and all danger of frost has passed.
2. Preparation: Because Spacemaster 80 is often grown in containers, use a high-quality organic potting soil mixed with compost. If planting in the ground, ensure the site receives full sun and has excellent drainage.
3. Sowing: Sow 2-3 seeds per pot or per space, about 1/2 inch deep. If planting in a row, space the plants about 12 inches apart. Spacemaster does not require a trellis, but a small cage can help keep the fruit off the soil in very tight spaces.
4. Watering and Care: Cucumbers are mostly water, so consistent moisture is the key to preventing bitterness. Water deeply at the base of the plant to keep the leaves dry, which helps prevent powdery mildew. Mulching helps retain moisture in the soil.
5. Harvesting: For the best flavor and texture, harvest Spacemaster 80 cucumbers when they reach 6 to 8 inches in length. Pick them frequently to encourage the plant to keep producing new flowers and fruit throughout the season.
