Growing Tips: Plant corn seed outside only when all risk of frost has passed. Sow seed 3 cm (1-1 ½”) deep, with 3 to 4 seeds per foot. Once sprouted, thin seedlings to 20 – 25cm (8-10”) apart in rows spaced about 60-75cm (24-30”). To enjoy fresh corn all season long, plant 3 or 4 varieties, all having different dates of maturity. Corn is a heavy feeder, side dress the stalks with fertilizer when knee-high and again when tassels form. Corn borer may be controlled with a drop of mineral oil applied to the inside of each ear after the silk has wilted.

The breeding of sweet corn has produced some exceptionally sweet and flavourful varieties. While SE and SH2 varieties are superior in sweetness to SU corn, they do have some drawbacks including slow germination in cold soils.
- SU Normal Sugary: The traditional sweet corn that contains varying degrees of sugar. Once picked, the sugar rapidly converts to starch. 
- SE Sugary Enhanced: These corn varieties have a higher sugar content than standard varieties of sweet corn, which allows them to maintain their sweet quality for a longer period of time. This is the preferred corn type for most growers. 
- SY Synergistic: Combines the characteristics of SU, SE, and SH2 varieties on one ear.
- SH2 Supersweet: Super sweet varieties have an extremely high sugar content and convert their sugars to starch much slower than traditional varieties. SH2 corn must be isolated from all other types of corn to prevent the kernels from becoming tough and starchy.
