Grow a delicious and dependable winter staple with Butternut Squash Seeds from Survival Garden Seeds. This classic heirloom variety produces smooth, tan-skinned fruits with deep orange flesh prized for its naturally sweet, nutty flavor and rich nutritional value. High in beta carotene, fiber, and vitamins A and C, Butternut Squash is an essential crop for sustainable, long-term food storage and homegrown nutrition.

Classic Flavor & Versatile Use:

  • Sweet, nutty flavor ideal for soups, roasting, mashing, or baking
  • Excellent substitute for pumpkin or sweet potato in recipes
  • Perfect for fresh eating, canning, freezing, or pureeing
  • Even the seeds can be roasted for a nutritious snack

Reliable Winter Bounty:

  • Stores for months in a cool, dry place—ideal for survival or homestead gardens
  • Strong producer that thrives in full sun and warm growing conditions
  • Each plant yields several medium to large fruits for lasting harvests

How to Grow Butternut Squash:

  • Sow seeds outdoors after danger of frost, when soil is warm (70°F or above).
  • Plant 1 inch deep in hills, spacing 3–4 feet apart in rows 5–6 feet apart.
  • Water consistently and mulch to retain moisture and suppress weeds.
  • Harvest when rinds turn tan and stems begin to dry; cure in a warm, dry spot before storage.

Harvest & Storage:
Cured butternut squash will store for 3–6 months in a cool, well-ventilated area. This long shelf life makes it a dependable, nutrient-rich food source for winter use.
