Sweetcorn is a variant of forage maize, but the cobs are smaller and the corns are very tender with a sweet taste. Golden bantam is a well known variety of sweetcorn.


They need a sunny, protected location with good garden soil.


  • Allow the cobs to mature until the husks turn brown.
  • Cut the cobs off and hang them up in a dry, warm room for several weeks.
  • Rub off the individual corns and dry them until they turn dark yellow.


Common purslane, Cucumbers, Peas, Pumpkin, Spinach

To sow directly, press the seeds about 4 cm deep into the moist soil, do not water.
Sweetcorn requires very little care.

  • Water regularly but sparingly.
  • Fertilise regularly e.g. with nettle swill.
  • Hoe weeds while the plants are small.
  • Apply a mulch layer (e.g. of straw or grass) between the plants
  • Earth up the soil as soon as the plants reach a height of 30 cm.
  • Soak the seeds in lukewarm water for about 10 hours.
  • Growing sweetcorn in blocks helps pollination by the wind and helps to support them.


Pests: Fruit flies, birds
Control: As soon as as any damage is visible, any control measures will be too late.


Sweetcorn is ripe as soon as the small hairs are brown.
Not all sweetcorn cobs ripen at the same time.


Immediately put corn cobs into cold storage after harvesting.


  • Remove all of the "silk".
  • Put the cobs in boiling water and cook for 10 to 15 minutes.
  • Then put the corn cobs into a pan with a little butter allow them to briefly simmer at a low heat.
Sweetcorn is free from gluten.
Sweetcorn should only be salted after cooking as the corns can harden otherwise.
