About winter squash

Winter squash — butternut, acorn, delicata — stores for months after harvest, supplying soups and roasted sides deep into winter from a single summer planting.

Spacing & yield

Winter squash wants 36×60 inches and about 10 lb per plant at ~100 days to maturity.

Growing tips

Train vines away from other crops by directing tendrils or using trellises for smaller varieties.
Slip a tile or board beneath developing fruit to prevent ground rot.
Leave squash on the vine until the rind resists a thumbnail scratch.
Cure in a warm, dry spot for 10 days after harvest to extend storage life.

Common mistakes

Under-spacing vines; they need at least 36 by 60 inches to develop full-size fruit.
Harvesting before rind is fully hardened, causing rapid spoilage in storage.

Harvest & storage

Cut stems 2-3 inches from the fruit once rinds are hard and colors deepen, around 100 days from sowing.

Store cured squash in a cool, dry location at 50-55 F for 3-6 months depending on variety.

Companion planting

Good neighbors for winter squash: corn, beans, nasturtium, marigold. Avoid planting beside: potatoes, other squash varieties nearby (cross-pollination concerns for seed savers).

Planting calendar

Start indoors about 3 weeks before last frost, then transplant 2 weeks after frost. Direct sow is also an option around 1 weeks after frost. Use the seed-starting calculator above with your real county frost date — the April 15 default is only a worked example (zone 6 style).
