In your picture on the newspaper, where you see the tubers all hanging from a central point, that is the top, you should see a little bit of stalk at the top. This goes just below the compost level, it will only shoot out from around there, it's no good planting just a bulbous bit, it won't grow.
so you can now see why you need a fairly big pot, because those tubers should hang downwards, they need to be covered in compost. Those thin fibre type threads are the roots, so these go downwards.
dont plant them out until they have grown into big plants, which should be around the end of May, they stand a better chance of not getting slug chewed. I have never used copper tape, but do use a very few slug pellets when first planted out.
