Potato plant grown in a tub suddenly wilted. As there are other plants in the same tub, I removed it. one tuber was complete mush--although others on the plant that were very small looked ok. I couldn't find any other signs of bugs or disease. Right now all other plants in this tub and in the others look ok. This is my first time growing potatoes, what should I be looking for and any advice to prevent further problem. We have had an uncharacteristically wet early summer and had a series of very rainy days last week. Don't know if that could have impacted. In general my garden is being attacked by more pests than usual this year.
