You can decide on your harvesting period depending on your varieties and your harvesting goals (early, conservation), your planting date and the earliness of your varieties.
This calendar will help you make the right decisions, bearing in mind that you can spread out your harvests and enjoy fresh potatoes throughout the summer!
Storage potatoes should be harvested once the leaves have completely wilted, to ensure thick-skinned tubers.
In dry weather, lift each plant with a spading fork, taking care not to damage the tubers. Leave to dry in the sun for a while before storing. For long-term storage, after removing any injured tubers, store the harvest in a ventilated, dry, dark place.
