Why Choose Squash Winter Butternut Waltham?

• All American Selections Winner: The AAS designation is awarded only to varieties that outperform all existing varieties in independent trials across North America — the highest recognition in home garden seed performance.
• Exceptional Sweet, Nutty Flavor: Rich, deep orange flesh with a naturally sweet, nutty flavor that intensifies in storage — no added sugar or seasoning needed for standout results.
• Outstanding Long-Term Storage: Stores 3–6 months in cool, dry conditions (50–55°F) — one of the best winter squash varieties for pantry storage and year-round use.
• High-Yielding: Each plant produces multiple 3–5 lb fruit throughout the season on vigorous vines.
• Disease-Tolerant: Strong resistance to common squash diseases — reliable performance even in challenging growing seasons.
• Nutritional Powerhouse: Exceptionally high in beta-carotene (Vitamin A), Vitamin C, potassium, and dietary fiber — one of the most nutritious winter vegetables available.
• Heirloom & Open-Pollinated: Save seeds year after year for a self-sustaining garden.
• Non-GMO: DNA structure never altered from natural traditional breeding methods.

Planting Tips for Success

• Sunlight: Full sun — at least 6–8 hours per day. Winter squash needs maximum heat and light for vigorous vine growth and well-developed fruit.
• Soil: Rich, well-drained soil with a pH of 6.0–7.0. Amend generously with compost before planting — Waltham Butternut is a heavy feeder. Plant in raised hills or mounds for optimal drainage.
• Planting: Sow seeds directly outdoors after all frost risk has passed and soil temps reach 60°F+. Plant 1 inch deep, 3–4 seeds per hill. Thin to 2–3 plants per hill once seedlings are established. Can start indoors 3–4 weeks before transplanting, though direct sowing is preferred to avoid taproot disturbance.
• Spacing: Space hills 4–6 feet apart; rows 6–8 feet apart. Butternut vines spread aggressively — plan for ample room or train vines vertically on a sturdy trellis.
• Watering: Water deeply once or twice per week at the base of plants. Avoid wetting foliage — wet leaves promote powdery mildew. Reduce watering as fruit approaches maturity to concentrate flavor and sugars in the flesh.
• Fertilizing: Apply a balanced fertilizer at planting. Side-dress with a low-nitrogen, high-potassium formula once vines begin running to support fruit development over foliage.
• Pollination: Butternut produces separate male and female flowers on the same plant. Male flowers appear first; female flowers (with a small fruit at the base) follow 1–2 weeks later. Hand-pollinate with a soft brush if bee activity is low in your area.
• Harvesting & Curing: Ready in 85–90 days. Harvest when skin is fully tan, the stem is dry and corky, and your thumbnail cannot pierce the skin. Cure at 80–85°F for 10–14 days to harden the skin and maximize sweetness before storage.
