Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Notes
Plant in blocks of at least 9 plants, all the same variety, to encourage pollination by the wind. Often planted with squash as they like similar conditions. Keep well watered in dry spells.
Harvesting
Harvest just before eating to get the sweetest taste, when the tassels at the top of the cobs turn brown to black. You can peel back the leaves and check the corn: if they ooze milky sap when pressed with a fingernail then they are ready.
