Squash Seeds

🌱 Summer & Winter Varieties

Squash are a versatile garden favourite, split into two main types: fast-growing Summer squash (like zucchini) and the slower-growing, sweet-flavoured Winter squash, which can be cured for long-term storage.

• Growing Essentials: Squash are a hot-weather crop. They thrive in full sun with deep, rich, organic soil (pH 5.5–6.5) and require plenty of water. Work in lots of compost before planting.

• Sowing: Direct sow outdoors from late May to early June, 2.5 cm deep in hills 2.4 m apart (4–6 seeds per hill, then thin to 3). If starting indoors 3 weeks early, use paper or fibre pots to minimize root disturbance, as they do not transplant well.

• Pollination Note: All squash produce male flowers first, followed by females. Ensure good pollination to avoid misshapen fruit.

• Harvesting: Protect mature fruit from frost and cold temperatures.
