How to tell it is ready

A mature winter squash has full variety color and a rind hard enough that a thumbnail does not puncture it easily. The surface often loses its glossy look and becomes duller as it matures. The stem turns corky and dry, and the plant often begins to decline. Fruits should be full sized for the variety and feel heavy for their size.

How to harvest

Cut fruits from the vine with pruners, leaving 2 to 4 inches of stem attached if possible. Never carry squash by the stem because it can break off and invite decay. Avoid bruising or scraping the rind during harvest. Keep fruit dry and handle each one as if it will be stored.

Timing

Most winter squash is ready 80 to 120 days after planting, usually in late summer or fall before hard frost. Harvest on a dry day when vines are mostly dying back and rinds are fully hardened. Morning is fine once surface moisture has dried.

After the harvest

Cure squash in a warm, dry place with good air movement for about 10 days if weather and variety allow. Then store in a cool, dry room, not in a cold refrigerator. Remove and use any damaged fruit first.

Tips

Do not harvest immature fruits for storage because they shrivel and rot sooner. Protect fruit from frost because cold injury shortens storage life even if the rind looks fine at first. Different varieties store for different lengths of time, so use shorter keepers first.
