Also, it is the root that needs the fertilizer/food not the tubers. So it pays to put seed potato on fertile soil with added fertilizer. You can of course give it fertilizer later but it has to get down to the root zone quickly.

Hmmm. Makes sense. So maybe I should put some compost under my sprouts along with some slow release fertilizer. I think the grow bag is deep enough to hill up around the stems. I also have 15 gallon bags if the 10's are not big enough. I was hoping to use the bigger ones for sweet potatoes though.
