Planting seed potatoes in the garden

Use healthy, suitable planting stock

Choose sound seed potatoes from a reliable source. A supermarket potato intended for eating is not necessarily suitable planting material and may carry disease concerns. Check the cultivar and whether it is described as early, second early or maincrop; these categories help plan harvest timing but do not guarantee results in every climate. Store planting tubers appropriately before use, avoiding freezing and damage.

Wait for workable soil

Plant when the ground is neither waterlogged nor excessively cold, taking account of local frost patterns. Compacted wet soil is difficult to work and may create poor conditions around the tubers. Prepare the bed so excess water can drain and roots can explore the soil. Follow cultivar and supplier guidance for planting depth and spacing rather than adopting a single figure for all potato types.

Protect emerging shoots

The tubers may be below ground while their shoots remain vulnerable to late frost. Watch forecasts and be ready to cover young growth or earth up appropriately when cold weather threatens. As stems grow, earthing up can help prevent developing tubers from being exposed to light, which causes greening. Avoid damaging stems and roots while drawing soil up around the plant.

Recognise plant health issues early

Monitor for unusual spotting, wilting or rapid decline, especially during humid conditions. Potato blight and other diseases need prompt, evidence-based handling; not every yellow leaf indicates the same problem. Rotate planting locations where practical, and do not use visibly diseased tubers for next year. At harvest, avoid cutting tubers with the fork and keep damaged potatoes separate from long-term storage.

Before you begin: three practical checks

• Choose healthy labelled seed tubers
• Wait until soil is workable
• Protect young shoots from late frost
