I know this might sound like a stupid question, but where on the plant do the new tubers grow? Off side roots of the main stem coming up from the seed? Will you get more spuds the more you earth up, and will they really develop if you use straw/mulch to earth up instead of soil, as some other threads on here seem to suggest? Please excuse my ignorance, like I say, this year will be my first attempt, and I'm just curious as to how all these various methods work...
Cheers!
