Christie I clipped something for you so check out my clippings. I think you can skip the sulfur and be fine. I didn't explain how to plant potatoes before because I don't do it the right way. I used to break up the soil lay them on top and put leaves over them. That way I could reach in to get new potatoes. I plant potatoes to get the new potatoes. To me store bought are just as good but not for new potatoes which are great fresh from the garden and small.
