how often do you water sweet potatoes?
We haven't had rain in about 2 wks. We aren't in a drought like many others, but it is dry. I am growing sweet potatoes for the second year. Last year we had more rain and I rarely watered. This year I am growing with black plastic for the first time. I am wondering how often I should be watering? Right now, I pour about half a watering can of water through the slit of each plant about once a week.
