Potatoes – looking poorly

QuestionsPotatoes – looking poorly
Ray Dunford Staff asked 13 years ago

I planted 2nd earlies (Maris Peer) in late Feb and early Mar 2011 into approx 14 tubs (2/3 plants in each tub). Most of the plants are still in flower but there 5/6 of them looking half withered and dying? The normally dark green leaf is now a very light green with brown spots. Am I in trouble?If so, are they all infected?
