Broad Bean Seeds – Growing Broad Beans in Northern Ireland

When to Sow Broad Bean Seeds in Northern Ireland

In Northern Ireland, broad beans can be sown in autumn (late October to early November) for overwintering, or from February to April for a spring crop. The region's relatively mild winters make autumn sowing a viable option in many gardens, especially in coastal or sheltered areas. Spring sowing remains popular for a reliable and productive harvest.

Overwintering vs Spring Planting

Overwintering broad beans are sown in late autumn and establish roots before going dormant. This method provides earlier harvests (often May) and frees up space for summer crops. However, well-drained soil and shelter from wind are essential. In inland or wetter sites, spring sowing from February to April is more dependable, giving strong crops from late spring into early summer.

Best Time to Plant Broad Beans in Northern Ireland

Direct sow autumn beans in late October or early November. For spring sowing, direct sow outdoors or transplant modules started under cover from late February onwards. Ensure 20cm spacing between plants in double rows and use canes or string for support as needed, particularly for taller varieties.

How to Grow Broad Beans in Northern Ireland

Broad beans prefer a sunny site with fertile, well-drained soil. Sow 5cm deep and water consistently during dry periods. Pinch out the top shoots once the lowest pods begin forming to prevent blackfly and direct energy into pod production. Harvest pods regularly to encourage continued cropping.
