Cucumber Seeds,
Boston Pickling

Sow Boston Pickling cucumber seeds after your last spring frost, once soil temperatures are at least 70°F. In cooler zones, start seeds indoors 3–4 weeks before transplanting. This variety loves warmth and grows quickly in raised beds, containers, or garden rows with full sun exposure.

Choose well-draining, fertile soil amended with compost or aged manure. Sow seeds 1/2 inch deep and space plants 12 to 18 inches apart in rows or hills. Install trellises or supports at planting time to guide vines and keep fruit clean. Keep the soil moist but not waterlogged during germination and early growth.

Water deeply and regularly, especially during flowering and fruit development. Apply mulch to maintain moisture and deter weeds. Fertilize with a balanced organic formula every few weeks. Trellising improves air circulation and makes harvesting easier. Pick cucumbers at 3–6 inches long for best pickling quality and to keep the plant producing abundantly.

• 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.
