| Hard to know without a photo. "Rotten looking spots" could be anything. It could be a disease or it could be insect damage that's now rotting. The first thing that popped into my head was potato scab. Rodney |

| Are they soft and rotten, or just black and scaly? |

| sometimes there will be little holes, like insects. they are usually not soft. just black and sometimes it so bad you just have to throw it away. they to hard to grow and gather to throw away. we can them for us and the kids family have a blessed day |

| Hard to tell without a picture, but if hard and black (don't know about holes) it sounds like scurf or scab, which is fine, just peel them. Keep the pH of the soil low, around 5.0 - 5.2, and don't use a lot of OM. Rotation helps, so does watering but mostly what you can do to control scab is to plant resistant varieties. http://vegetablemdonline.ppath.cornell.edu/factsheets/Potato_Scab.htm Scurf is a little harder to deal with, I see store-bought potatoes with scurf all the time. Crop rotation helps, as does early harvesting (which you're already doing), but the best thing is to try to get certified disease-free seed potatoes, don't use store-bought potatoes or ones you save from this year. Fungicides don't seem to work. http://vegetablemdonline.ppath.cornell.edu/factsheets/Potato_SilverScurf.htm |
