Summer Squash Growing Basics

Squash has been cultivated in the Americas for thousands of years. Summer squash differs from winter squash mainly in when it is gathered: the fruits are harvested young, while the skin, seeds, and flesh are still tender. Zucchini, yellow crookneck, straightneck, cocozelle, and pattypan all belong to this broad group.

Most summer squash grows on compact, bushy plants that produce heavily once warm weather arrives. Sow into warm soil, leave plenty of room around each plant, and keep moisture steady through flowering and fruit development. Check the plants often—small fruits can reach harvest size in only a few days.

Sow outdoors after frost danger has passed and the soil has warmed to at least 60–65°F. Cold, wet soil slows germination and increases the chance of seed rot.

For an earlier start, sow indoors 2–3 weeks before transplanting. Move plants outside only after nights remain above about 50°F and the soil is warm.

In long-season areas, a second sowing in early or midsummer can replace older plants affected by pests or disease.

Direct sow seeds about 1 inch deep. Space bush varieties 24–36 inches apart, with enough room between rows for airflow and harvesting. For hill planting, sow several seeds and thin to the strongest two or three plants.

Start indoor seedlings in individual pots because squash roots dislike disturbance. Transplant while plants are small, usually with no more than two or three true leaves.

Keep the soil evenly moist during germination. Avoid saturated conditions, especially before seedlings emerge.

Choose a site with full sun and fertile, well-drained soil. Work compost into the bed before planting, but avoid excessive nitrogen, which can encourage leaves at the expense of flowers and fruit.

Water deeply at soil level whenever rainfall is lacking. Consistent moisture is especially important during flowering and fruit development. Mulch after the soil has warmed to conserve moisture and limit soil splash.

Squash produces separate male and female flowers. Male flowers usually appear first. If small fruits begin to grow and then yellow or rot, poor pollination may be the cause.

Harvest elongated squash such as zucchini and yellow squash when they are about 6–8 inches long and the skin is still tender. Pick pattypan types when they are roughly 3–4 inches across.

Check plants every day or two. Once pollinated, fruits can reach harvest size within a week. Frequent picking keeps the plants flowering and producing.

Cut fruits from the plant with a knife or pruners, leaving a short stem attached. Remove overlooked, oversized fruits even if they are no longer tender enough for the table.
