For a laugh, I took a couple of store bought potatoes (Desiree), and put them in the ground. They seem to have grown quite well, and some of them are even starting to pop up from the soil.
I've read that you should add extra soil on top to keep the potatoes from going green - I shall do that. I'm just wondering when I know it is time to lift them.
I have no idea what i'll find, or what size - it was just an experiment. The green bits which grow on top are quite large, and there are flowers. We've been getting alot of rain, so they have been watered well.
Any other tips? Is it ever too early or too late to dig them up?
