Q.What Can I Do With Soil That’s Had Potato Blight?
We grow our potatoes in large containers – clean soil every crop. Unfortunately our Xmas crop was destroyed by blight in October while we were away so were cut down immediately and all foliage was destroyed. I’ve looked everywhere online for help to know what we can do with the soil… can we put it on the garden? Do we have to clean it in some way? Use it for anything? Do we have to wait for a certain length of time? Help would be greatly appreciated.

Sterilizing your soil will make sure there are no "hosts," such as living plants, weeds or viable seeds, that the blight can live on between seasons. Here's an article that explains how to solarize your garden soil. You may need to let this continue into the hotter summer months.
