Certified Organic Heirloom Winter Squash Yielding Heavy Crops of Smooth, Sweet, Deep-Orange Flesh.
Waltham Butternut Organic Winter Squash (Cucurbita moschata) is an all-time favourite open-pollinated heirloom, now available as certified organic seed.

Featuring a small seed cavity localized in the bulbous base, each squash is packed with thick, fine-grained, deep-orange flesh that is rich, sweet, and completely fibreless.

What you need to know to Plant & Grow
Squash are heat-loving crops that thrive in full sun with organic-rich soil and careful transplanting to protect sensitive roots.
-
Direct Sowing (Recommended): Direct sow seeds outdoors from late May to mid-June once soil temperatures have warmed thoroughly. Plant seeds 2.5 cm deep in hills spaced 2.4 m apart, placing 4 to 6 seeds per hill. Thin to the 3 strongest seedlings per hill after emergence.
-
Indoor Starting: In shorter-season regions, start seeds indoors 3 weeks before outdoor planting. Sow directly into paper, fibre, or peat pots to avoid root disturbance during transplanting.
-
Soil Preparation & Watering: Work generous amounts of rich compost or well-rotted organic matter into garden beds prior to planting. Keep plants evenly watered throughout the growing season for optimal fruit development.
-
Harvesting & Storage: Harvest mature squash before the first hard autumn frost when the skin turns a uniform tan-cream colour and hardens. Cut from the vine leaving a short stem section attached. Cured fruits store exceptionally well in a cool, dry location for long-term winter eating.
