Cucumber Seeds,
Armenian Yard-Long

Start Armenian Yard Long cucumber seeds outdoors after the last frost, once the soil warms to at least 75°F. In cooler areas, start seeds indoors 3–4 weeks before transplanting. These long-season, heat-tolerant vines love summer conditions and perform best when planted in raised beds or mounds. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Choose a sunny site with well-draining, fertile soil. Direct sow seeds 1/2 inch deep, spaced 18 to 36 inches apart. If transplanting, harden off seedlings before setting them outdoors. Use compost-enriched soil to boost early growth. Provide trellis support immediately to train vines upward for straighter, cleaner fruit development.

Maintain consistent moisture, especially during flowering and fruiting. Water at the base to prevent leaf diseases. Feed with a balanced organic fertilizer every 3–4 weeks. Trellising improves airflow and fruit shape. Harvest cucumbers when 12–18 inches long for best flavor and texture, though they can grow much longer without losing quality.

• 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.
