I am having the same problem. One at a time they seem healthy, then the leaves start to wilt, then the plant
just dies. The ones right next to them still seem healthy? I have not tried to dig anything up yet - they are only about 2 months old. I am puzzled. This is my 1st year of potato plants
. wondering if I might be over watering, or wrong soil (compost mix from the yard & garden store). Any help would be appreciated.
