There is no need to isolate Casino from other varieties, but plant seeds in blocks of at least 4 parallel rows to ensure good wind pollination and well filled out ears. Corn is a heavy feeder, so add plenty of compost or aged manure to the soil at sowing time, and then fertilize when young plants are 7 or 8 inches tall and again as ears begin to form.
HARVEST AND USE
Well filled out ears of corn are ready to eat when the silks are very dark brown but not dried out. Test by choosing a plump ear and peeling back the husk very slightly. The kernels should be tender and milky when slit with a fingernail. Luscious is a SE corn, so the tender crisp kernels will hold their sweetness after harvest.
