Planting Guide:

We recommend planting Main Crop potato tubers, such as International Kidney, outside between March and April, 10cm deep and 20cm apart in a line. Leave at least 30cm between lines to allow growing space.

Prior to planting, encourage Seed Potatoes to sprout by placing them on a cool, bright windowsill for 4-6 weeks. This process is known as ‘chitting’ and will help prepare the potato tuber for going in the ground.

Once planted, ‘earth up’ the potatoes by drawing the soil up around new shoots to protect them from frost damage and prolong the growing time. Earthing up also protects developing potatoes from sunlight which causes them to turn green and poisonous. Keep potatoes well watered during warm weather.

Main Crop Seed Potatoes require a much longer growing time in the ground and would benefit from an added fertiliser during the Summer months.

Harvesting Guide:

When ready to harvest, cut back haulms (plant stalks) to ground level before gently lifting the plant up with a garden fork.

Carefully remove the potatoes from the plant and wash well before use in the kitchen.
