Plant squash in a sunny, sheltered spot with fertile, well-drained soil, ideally enriched with plenty of organic matter. Space plants around 1.5m (5ft) apart to allow room for sprawling vines, and water consistently to keep the soil moist but not waterlogged, especially during dry spells. Mulch around the base to retain moisture, suppress weeds, and keep the developing fruit clean.

Support young plants by checking for slugs and removing any damaged or diseased leaves. Feed lightly during the growing season with a balanced fertiliser or compost tea to encourage strong growth and abundant fruiting. Harvest summer squashes when the fruits are tender and still immature, picking regularly to encourage further production.

For autumn and winter cultivated varieties, leave fruits on the vine until the skin has hardened and the colour is fully developed, then cut carefully with a sharp knife, leaving a short stem attached for storage. Store winter squash in a cool, dry place for several months.
