Sweet corn is not a difficult vegetable to grow these days. there are some good varieties available for growing in most situations.

What you need to do to grow your own sweet corn successfully.

  • Sweet Corn needs a long growing season to mature and produce the cobs before the autumn sets in.
  • Grow it in the sunniest, sheltered position in your garden or allotment.
  • Sow the seed indoors in April in single pots. They will not germinate outdoors until it is too late to provide a good Sweet Corn plant. They hate root disturbance - so individual pots are better then seed strips.
  • If you insist on sowing outdoors, then wait until may and space the seeds (two to a station) 15in apart.
  • If you are growing just a few plants, then they are best planted in 'blocks' rather than in long rows. If you are planting in rows - aim for at least three rows to help with the pollination.
  • Sweet corn are normally pollinated with the help of the wind.
  • Keep them well watered and with regular feeding throughout the summer. Liquid Tomato feed is good - or Seaweed extract.
