I have had a problem with scab. But last year, when I dug my potatoes they were beautiful. I had moved my potatoes to a totally new location. After storing in the basement, they are now developing a rough skin that doesn’t look like scab. The potatoes are solid and beginning to sprout, but when I peel them they have tiny pepper size dots that I cut out. I plant red Pontiac potatoes. What is causing this? The potatoes show no rot or softness. I do not use manure but do use leaves that are composted. I would be grateful for any suggestions. Thank you KK
