Thanks so much, Can we put Blight free potatoes such as Cara in the infected ground next year, and also some plot holders are asking about liming the soil over winter.?
Cara is a blight-resistant variety rather than blight-free. There's a difference. They will still become infected if the pathogens arrive on the breeze and the weather conditions are conducive. They will just battle on a bit better than non-resistant varities. But, to answer your question, you can certainly plant them.
I'd only lime the soil if the soil needs it. Spuds like soil slightly acidic. Lime will send the soil's pH in the other, wrong, direction. It's a good idea to invest in a soil pH test kit and test the soil before amending it.
