Over-night temperatures on May 22 to 23 dipped to -2 to -3 oC in many parts of Ontario. Cereal crops are hardy to light frosts. Leaf tissue on plants that have not hardened off will withstand temperatures of -4 oC or lower before the cells will freeze and damage occurs, making late spring frosts of little consequence.
