Potatoes with a high concentration of solanine taste bitter and are harmful when consumed in large quantities. However, even a single dish of green tubers can cause nausea, headache and dizziness.
In order for your harvest not to spoil, not to turn green, it just needs to be properly stored in a cool, dry, dark place with minimal lighting.
If there is no dark place, then you can use dark agrofiber so that it breathes. In no case do not use black garbage bags: firstly, they create a greenhouse effect and potatoes can rot; secondly, Ukrainians need them for other purposes nowadays.
