Juanita, Purchased soil may contain some nutrients, but it will be depleted quickly as the plants use it, and washed out from watering. You will need to feed with additional all-purpose fertilizer to nourish the plants and keep them healthy.

Karen, Potatoes do like cooler soil. You could try moving them daily to the shade. Potatoes will grow in partial shade too, just at a slower rate and will produce smaller potatoes. With that being said, I would give it a try. Also consider growing potatoes in the cooler weather of fall for a winter harvest.

Maria F, Potatoes cannot survive frost or freezing temperatures. I would bring them in if you can, or harvest now.
