Sweet Corn

Sweet Corn is another one of those vegetables that tastes so much better picked and cooked fresh. Sweet Corn must be grown in a sunny spot sheltered from strong wind. As the plants are wind pollinated they should be grown in blocks with the plants 25cm apart.


Sow at 18-21°C. The plants hate root disturbance so sow indoors from August in peat pots; setting the seeds 2.5cm deep. Otherwise sow seed directly into the garden from October. Sow two seeds one inch 2.5cm deep, 25cm apart in rows 50cm apart; remove the weakest seedling.


Plant out indoor-raised plants early October depending on the weather. Stake tall varieties if the position is windy. When roots appear at the base of the stem cover with soil. Water well in dry weather; this is vital when the plants are flowering. Liquid feed when the cobs begin to swell. Tap the tops of the plants when the male flowers (tassels) open to help pollination; poor pollination will result in poorly filled cobs. Many varieties of corn should not be grown close together as cross-pollination can occur.

Test for ripeness when the tassels have turned chocolate brown; squeeze a grain between thumbnail and fingernail - if a watery liquid squirts out then it is unripe, if it is creamy the cob is ready. Twist the ripe cob from the stem.
