I have a question about my potatoes. I planted a light skinned, I believe it was Yukon Gold, potato. I have graveled a few and the skin is red. I am puzzled. Can you give me an answer? Thanks. cheadr

If it is a blotchy red, it could be blight on the potatoes, but you would likely also see some unhealthiness in the foliage as well.
Another possibility is that the seed potatoes were mislabeled. The fungicide that was used to treat them may have masked the red color and had given them a lighter colored cast.
