Waltham Butternut was selected in Massachusetts and became a widely grown American standard for uniform butternut shape, a long solid neck, deep orange flesh, good kitchen yield, and storage quality. Institutional cultivar records describe the familiar tan fruit and long vines. The named variety belongs to the twentieth-century breeding history of butternut squash, while Cucurbita moschata has a much older domestication history in the Americas. Waltham Butternut squash seeds produce uniform tan butternut squash with deep orange flesh and a small seed cavity. Waltham Butternut squash seeds are warm-season seed. Give runners a planned direction so leaves receive air and fruit can rest on a dry surface. Female flowers need repeated pollinator visits for complete fruit set.

Saving seed
Seed saving for Waltham Butternut Select several healthy, true-to-type plants so the saved lot represents the variety rather than one unusually early or large individual. Squash and gourds are insect-pollinated and cross readily with other varieties of the same species. Confirm the species identified for this crop, then isolate by distance or controlled hand pollination. Mark seed fruit and let it reach full biological maturity; summer squash must become large and hard, winter squash must develop full rind color, and luffa or hard-shell gourds must mature well beyond the edible stage. Cure sound fruit before extraction when the crop benefits from curing. Remove, wash, and dry seed to a hard, storage-ready condition. Maintain several representative plants and record species, population, isolation, fruit selection, curing, cleaning, and test date.
Common problems
Watch Waltham Butternut for cucumber beetles, squash bugs where applicable, aphids, powdery or downy mildew, bacterial wilt, crown rot, poor pollination, and fruit damage on wet soil. Rotate cucurbit crops, provide airflow, water at the root zone, protect young plants before flowering, and remove covers when blossoms need pollinators. Do not work wet vines.
