Growing sweet corn in home gardens

Quick facts

  • Know what genetic type of corn you are planting.
  • Isolate different types of corn to prevent cross-pollination.
  • Direct seed corn in the garden after the soil has warmed.
  • Irrigate to prevent drought stress.
  • Harvest when kernels are full and "milky" when squeezed.

Crisp and tender sweet corn 

There are many types of sweet corn available to gardeners. New varieties have made it easier to bring quality sweet corn to the table. New types are sweeter, crisper and tenderer. They hold their sweetness longer without becoming starchy after picking, but growing these new types can be more challenging.
