How to Grow Squash: Easy, Abundant, and Deliciously Versatile

New to vegetable gardening? Start with squash. Nearly guaranteed to thrive and produce abundantly, even for first-timers. Experienced? Branch out from zucchini and crookneck—dozens of varieties await. Cooks love the range: edible blossoms, quick summer grills, long-term storage for soups and winter baking, breads, relishes, desserts.

All squash are warm-season, but “summer” vs. “winter” refers to harvest time and storage. Summer squash: harvested young, skin edible, eaten in summer. Winter squash: harvested late summer/early fall, hard inedible skin, stores months. Planting and care are the same.

Traditionally sprawling, but compact/bush varieties increasingly available for small spaces.

Days to maturity: Summer 45–65; winter 60–110.
Light: Full sun.
Water: Regular.

Favorites:
Summer: Early Yellow Crookneck, Pic-N-Pic, Sundance (crookneck); Benning’s Green Tint, Peter Pan, Sunny Delight (patty pan); Early Prolific, Zephyr (straightneck); Black Beauty, Cocozelle, Costata Romanesco, Eight Ball, Green Tiger Striped (zucchini).
Winter: Honey Bear, Table Ace, Table King, Table Queen (acorn); Banana; Blue Hubbard (hubbard); Bon Bon Buttercup, Early Buttercup (turban/buttercup); Burpee’s Butterbush, Pilgrim Hybrid, Waltham Butternut (butternut); Cornell’s Bush Delicata; Lakota; Spaghetti.

Planting. Warm, sunny, well-drained fertile site. Sow ~2 weeks after last frost, soil 70°F (21°C). Start indoors ~1 week earlier.
Vining summer squash (sprawl to 4 ft): sow 2–3 in. deep, 12–18 in. apart, rows 6–8 ft apart; thin to 4–5 ft. Same spacing for transplants.
Hills: 4–5 seeds per hill, rows 7–8 ft apart; thin to 2 plants/hill.
Bush: 1 ft apart, rows 3–5 ft; thin to 2–4 ft. Pots: large container best.

Largest winter squash (banana, melon) need more room—fruits 1.5–2.5 ft long. Conserve space: grow on sturdy trellis (most squash; zucchini exception).

Caution: Don’t overplant. Midnight doorstep zucchini drops make neighbors hunt you down.

Care. Water deeply after planting, ~1 in./week. Flood soil or soaker hose; wet leaves/stems/flowers invite mildew. Fertilize at flower/fruit set.
Board or foam under winter squash prevents rot. Support trellised fruit with cloth bags/netting—fruit gets heavy.
Pests: aphids, cucumber beetles, cutworms, mites, nematodes, squash borers/bugs. Mildews. Row covers protect young plants; remove at blossom for pollination. Resistant varieties for borers.

Harvest. Summer: ~2 months after planting. Crookneck/scallop: 2–3 in.; zucchini/straightneck: 4–6 in. Cut stem close with sharp knife/shears (stems irritate—wear gloves). Stay on top—overnight tiny zucchini becomes monster.
Winter: vines dried, skin hard (can’t dent with fingernail). Survives light frost; harvest before heavy frost. Cut stem 2 in. above fruit. Cure outside until stems shrivel, store dry at ~55°F (12°C). Keeps 2–6 months.
