potato leaves turning brown
Potatoes planted first of April and growing well. Last few days the leaves are turning brown and drooping down. Why? I am consistent with watering, but daily temperatures have been averaging around 95. Now all plants are affected. Brown leaves started with one plant and now four are affected.
