Not only are my spuds (stored in the porch - one of the perils of an upstairs flat) starting to sprout, but one potato in each of two bags has gone spectacularly rotten, and eaten a black nasty hole in my nice hessian potato sacks.
What's really weird, though, is that the rotten spud has then dessicated, and although it's eaten a hole in the bag, it's hardly affected the potatoes in contact with it. Don't get that!
Annoyingly, I didn't think to take a photo of the affected spuds - I'll check the council food waste bin tonight, see if they're still in there.
