Plant out hardened off plants after the last frosts. Arrange the plants in a grid pattern, 35cm apart, as this will aid wind pollination. Cobs are ready to harvest when the tassels turn brown and the kernels exude a milky fluid if pierced with a thumbnail. See Sweetcorn cultivation for further information
