How to grow Winter Squash, step by step
Sow on warm mounds
- Direct-sow after frost in warm soil on rich hills; thin to the strongest.
- Give it room — vines run 6–12 ft.
Feed, then let it run
- Rich soil and steady water size up the fruit.
- Let vines sprawl or train them; mulch keeps fruit clean.
Harvest hard-skinned, then cure
- Pick when the rind is hard and the stem corks; leave a stub of stem.
- Cure 1–2 weeks warm, then store in a cool, dry room for months.
Winter Squash problems & fixes
Winter Squash — Fruit rots before ripe: what's wrong and how do I fix it?
Poor pollination or damp soil. Encourage bees; set fruit on a board or mulch.
Winter Squash — White powder on leaves: what's wrong and how do I fix it?
Powdery mildew, common late. Improve airflow; it usually still ripens the crop.
Winter Squash — Won’t store: what's wrong and how do I fix it?
Picked unripe or uncured. Wait for a hard rind and corked stem, then cure before storing.
Recommended winter squash varieties
