Golden Jubilee corn seeds are the highest-yielding, main crop variety for canning or freezing. The tall plants bear 20-25cm (8 1/2-9") ears that have 16-20 rows of deep, sweet, yellow kernels with a rich corn flavour. If you don't process or cook the cobs soon after harvest, they only stay sweet for a relatively short time. But cooked fresh, they are sweet and flavourful, and worth waiting for. Make sure that the soil temperature is 15°C (60°F) before planting these untreated corn seeds. Corn is wind pollinated to it needs to be planted in blocks as opposed to single rows. Isolate Golden Jubilee from all other super sweet varieties for the best results.
Matures in 95 to 105 days. (SU hybrid sweet seeds)
These big plants will grow in almost any soil, but getting the cob to mature is another matter. The maturity of the ears (cobs) is not controlled by the size of the plant, nor by day-length, but by the accumulated heat the plant has had while it grew. They call this the “heat units”. Only temperatures above 50 F count after the last killing frost of spring. Temperatures above 50 F add up to create the heat units. Corn plants generally grow very tall, and will shade other vegetables. Some plants will benefit from this shade, such as lettuce, but heat-loving plants must be placed so that the corn does not shade them. This heavy-feeding plant also provides a stalk for plants such as Pole Beans. Follow along with this handy How to Grow Corn from seeds Guide and grow food.
