Known as 'Jersey Royals' when grown on the island of Jersey, these main crop potatoes are perfect for boiling with extremely thin skin which is kept on when boiled, and an almost buttery taste which few other varieties can match. Harvest potatoes early to enjoy 'baby' new potatoes that are perfect for salads.\u003c\/p\u003e\n\u003cp\u003eInternational Kidney potatoes can also be left in the ground for an extra month or two in order to bulk up to a floury maincrop potato which is not as good for boiling but is excellent for roasting, chips and wedges.\u003c\/p\u003e\n\u003ch2\u003eHow to plant\u003c\/h2\u003e\n\u003cp\u003ePlant International Kidney Main Crop potato tubers outside between March and April, 10cm deep and 20cm apart in a line, making sure to leave at least 30cm between lines to allow growing space.\u003c\/p\u003e\n\u003cp\u003ePrior to planting, Seed Potatoes should go through the process of 'chitting'. This process involves leaving the potatoes on a cool, bright windowsill for 4-6 weeks in order to encourage sprouts and prepare the tubers for going into the ground.\u003c\/p\u003e\n\u003cp\u003eAfter planting, draw up soil around the new shoots to protect them from frost damage and prolong the growing time. 'Earthing up' in this way also protects developing potatoes from sunlight which can cause them to turn green and poisonous. Keep potatoes well watered during warm weather.\u003c\/p\u003e\n\u003cp\u003eMain Crop Seed Potatoes require a longer growing time in the ground and would benefit from an added fertiliser during the Summer months.\u003c\/p\u003e\n\u003ch2\u003eHow to harvest\u003c\/h2\u003e\n\u003cp\u003eWhen ready to harvest, approximately 16-22 weeks after planting, cut back plant stalks to ground level before gently lifting the plant up with a garden fork.\u003c\/p\u003e\n\u003cp\u003eCarefully remove the potatoes from the plant and wash well before using in the kitchen.\u003c\/p\u003e\n\u003ch2\u003eDetails\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 2kg bag (16-28 tubers)\u003c\/li\u003e\n\u003cli\u003eWhen to chit potatoes: 4-6 weeks before planting\u003c\/li\u003e\n\u003cli\u003eWhen to plant: March, April\u003c\/li\u003e\n\u003cli\u003eWhen to harvest: July, August, September, October (16-22 weeks after planting)\u003c\/li\u003e\n\u003cli\u003ePlanting depth: 10cm\/4\"\u003c\/li\u003e\n\u003cli\u003eBulb spacing: 20cm\/8\"\u003c\/li\u003e\n\u003cli\u003eSoil type: Moist but well-drained\u003c\/li\u003e\n\u003cli\u003eSoil pH: Acid, Alkaline, Neutral\u003c\/li\u003e\n\u003cli\u003eSunlight: Full sun, Partial shade\u003c\/li\u003e\n\u003cli\u003eHardiness: Tolerant of low temperatures but will not survive being frozen\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kapiteyn","offers":[{"title":"Default Title","offer_id":56082320064837,"sku":"1186877","price":4.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/7458\/1061\/files\/4ffdc080-international-kidney-main-crop-seed-potatoes-2kg-bag.jpg?v=1761657642","url":"https:\/\/www.gatesgardencentre.co.uk\/products\/international-kidney-main-crop-seed-potatoes","provider":"Gates Garden Centre","version":"1.0","type":"link"}
