Cucumber Seeds,
Dragon's Egg

Direct sow Dragon’s Egg cucumber seeds after the last frost when soil temperatures are at least 70°F. In cooler climates, start seeds indoors 3–4 weeks before transplanting. These warm-season plants thrive in full sun and fertile, well-drained soil for optimal growth and fruit production.

Plant seeds 1/2 inch deep in nutrient-rich, well-drained soil. Space them 12 to 18 inches apart in rows or mounds, with ample room for vine spread. Install a trellis at the time of planting to keep fruits off the ground and ensure easy harvesting. Keep soil evenly moist during germination and early growth.

Water regularly at the base to avoid foliar diseases and maintain consistent moisture. Fertilize with compost tea or organic fertilizer every 2–3 weeks. Trellised plants benefit from better air circulation and straighter fruits. Harvest when cucumbers reach the size of a goose egg—about 3–4 inches—for peak flavor and texture.

• Select disease-free plants for seed saving.
• Allow fruits to fully ripen on the vine (they will turn yellow or orange).
• Scoop out seeds and pulp into a jar or bowl with water.
• Ferment at room temperature for 2–3 days, stirring daily.
• Rinse seeds thoroughly and dry on a screen or paper towel for 1–2 weeks.
• Store in a cool, dry place in a labeled and dated airtight container.
