Planter bags are suitable for growing potatoes where space is limited, such as patios or paved areas.

• Use a 40–45 litre planter bag and plant 3–5 seed potatoes per bag.
• Ensure the bag has good drainage and use a general purpose compost. Do not use garden soil.
• Add 15 cm (6 inches) of compost to the base of the bag.
• Place seed potatoes with the eyes facing upwards and cover so they sit around 5 cm (2 inches) below the surface.
• Water lightly at first. Once plants reach around 40 cm (16 inches) tall, keep the compost evenly moist.
• As shoots grow, continue adding compost to cover the stems and prevent tubers from turning green.
• Harvest as needed once plants have flowered, or wait until foliage dies back for a full harvest.
