Growing Sweet Corn

Growing Sweet Corn
Originally a native of sub-tropical areas, sweet corn is the only vegetable which grows in darkness. 

Sweet corn freshly picked from the garden is far tastier than those from shops. The reason is that the sugar in sweet corn quickly turns to starch giving a very dull flavour after only a day or so. Freshly picked sweet corn is also very nutritious, each cob giving roughly 22% of the daily requirement for Vitamins A and C, Magnesium and Iron.

A little care and planning in the early stages will go a long way to ensure that tasty sweet corn can be grown successfully in many areas.

Where To Grow Sweet Corn

Sweetcorn with immature tasslesSweet corn must be grown in full sun, where shelter from strong winds is provided. It is not too particular about the soil, although it hates clay. Because sweet corn sends down deep roots, it prefers a deeply dug bed. 

Sweet corn pollinates best when sown in a block, so for planting, a minimum area of 1.2m (4 ft) square is required.

Message: Give everything a try! Sweetcorn is usually subtropical, you should be OK, it does well throughout Africa. If you cant buy seed at a garden centre, buy from a petshop or corn merchant.

Message: I have corn growing in my flower garden under my patio, the corn stocks are huge. I did not plant them they just started growing. I also have a stock coming up through a small crack in the cement. The soil is mostly clay I added potting soil to cover the bottom of the stock. Should I do anything or just let it grow?
