potatoes main crop harvesting..
This is rather a pain, I grew King Edwards main crops in several tubs and have harvested about 2/3rds so far. I stored the unwashed booty in a large hessian sack in a cool dry place. Today I cooked up a few and to my dismay, some potatoes didn't seem to cook normally and these had a more solid icy feel and were not nice..
There was no sign of any diseased tubers.. I cannot therefore pick them over an discard the dodgey ones.. What is this problem as I have never had this happen before.. Any way of preventing this happening again would be appreciated..
