Butternut, acorn, delicata, spaghetti, kabocha — winter squash are the keepers of the garden, curing to last months in storage. They need space to sprawl, but the harvests make it worthwhile.
Winter squash grows in Zones 3–11. In Zones 3–5, choose shorter-season varieties and start indoors 3–4 weeks before last frost to maximize the growing window.
How to Grow Winter Squash: Step-by-Step
- Cure harvested squash at 80–85°F for 1–2 weeks to harden skin
- Avoid overhead watering — wet leaves accelerate powdery mildew
- Fertilize at planting and when vines start running
- Pinch off late-season flowers that won't mature before frost
- Store cured squash at 50–55°F for months of eating
