Corn is a hot season grass: it likes growing in large fields with lots of other corn plans near it. Most home gardens are not large enough to grow good corn (you can grow it, but the corn will not do as well - this can still be good enough.) With sweet corn time from field table is critical to good flavor, so people do grow it in their garden anyway, but it would be better to live next door to a large corn farm that you get it from.
