We had already established that frost was the root of Bruce’s problem. His corn plants were brown and wilted as a result of the temperature dipping to around -3 C for several hours. The tricky question Bruce faced was whether or not to replant.
There are a number of factors we had to weigh, including plant survival, loss of yield due to both potential lower stand and later planting date. After weighing all of these and looking closely at the plants, I advised him not to replant. And, indeed, after several days his crop outgrew its frost symptoms. The damaged leaves were replaced with new leaves within a week.
