Pototoes

Q: Even though I knew better, I planted my potatoes only two inches deep. Should I pile dirt around them to protect them?

A: To protect the developing potatoes from growing at the surface and being exposed to light, yes. As you know, if daylight reaches the surface of potatoes, they will turn green and taste bitter. Even more important, piling dirt around the stems will increase the size of your harvest. Since no potato can grow deeper than the seed potato which was planted, your plants can produce very few new potatoes in the two inches of dirt available to them.

I would start building mounds...
