Short to medium term on-farm potato storage to reduce sprouting and rot without cold storage.

Without a cold store, potato can only be held for a limited time, but you can reduce losses with care. Harvest mature tubers when the skin has set, cure them in a cool, dark, airy place for about a couples of weeks so small cuts heal, and remove cut, diseased or greened tubers before storing. Store in a cool, dark, well ventilated place; light causes greening, which makes tubers bitter and unsellable. Keep them off the bare floor on a slatted base so air can move, and keep the heap shallow enough that the bottom does not get crushed and heated. Avoid damp, which brings rot, and avoid heat, which speeds up sprouting and weight loss. Check regularly and pull out any rotting tubers. For long holding of several months you really need cold storage, because at warm room conditions potato sprouts and loses weight fast. Verify curing time and safe holding period for your variety and climate with your local agriculture office or KVK.
Darkness is everything for potato at home. The moment light gets in, the tubers turn green and the buyer cuts the price.
