Waltham Butternut is the benchmark for butternut squash—uniform, tan fruits with small seed cavities and dense, sweet, nutty flesh that stores for months. Bred in Massachusetts in the 1960s, it still outperforms most hybrids for flavor and yield. High in beta‑carotene and fiber, it’s the backbone of winter soups and roasts. Give vines space, mulch to hold moisture, and cure fruits in the sun before cellaring. One planting, many winter dinners—that’s Waltham’s promise.

How to Grow

Start seed indoors 3-4 weeks before transplanting into the garden. Optimum soil temperature for seed germination is 65-85 degrees. Transplant to the garden 2 to 3 weeks after your average last frost. Or, plant seeds directly in the garden 1-2 weeks after average last frost date. Sow 3-5 seeds per hill, thinning to a final 2-3 plants per hill. Squash grow best in a warm site with full sun. Warm soil is essential to good seed germination and emergence. Using transplants can speed production.
