Many years ago, I used to know a woman who deliberately spread her potato peelings around her garden in every nook and cranny wherever there was a naked bit of soil. Every year she would dig up pound after pound of beautiful, organic potatoes.
If you have spare soil in your garden this is one crop worth trying out - and it's free. Potatoes grow very easily from peelings especially if there are a fair quantity of eyes in the skin. Please remember to wait until after the plant has flowered before digging up the crop. NEVER eat the small green tomato looking fruits that appear where the flowers have been they are very poisonous.
Potatoes and tomatoes belong to the nightshade family which is why their flowers look so very similar.
