(Best months for growing Sweet corn in South Africa - Semi-arid regions)

  • P = Sow seed
  • Sow in garden. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 16°C and 35°C. (Show °F/in)
  • Space plants: 20 - 30 cm apart
  • Harvest in 11-14 weeks.
  • Compatible with (can grow beside): All beans, cucumber, melons, peas, pumpkin, squash, amaranth
  • Avoid growing close to: Celery.
  • A seedling
  • A young corn plant
  • Feathery cobs on side of stem. Male flowers at top.

Plant in 4 by 4 blocks to encourage germination Pick when the silky threads on the cobs turn brown or black. Part the top of the leaves and test for ripeness by pressing a grain with your fingernail. If it is milky, it is ready.

Early varieties ripen quickly and are sweeter when just picked.

Avoid planting coloured maize ( for drying) near sweetcorn as they will cross-pollinate and spoil the cobs on both.

Culinary hints - cooking and eating Sweet corn

Pick and cook within an hour. Remove the silks and outer leaves.
Best flavour if microwave about 4 minutes per cob.
Can be barbequed wrapped in foil
Cook large amounts in a stock pot until test soft.
Sprinkle with black pepper and dip in butter.

Dear Sir, i have planted papaya trees in my yard. They are organic & flourishing very well . People got amazed when they see our papayas, they look different from south african pawpaws. They are very sweet & juicy, have also smaller trees growing. I also planted brocolli, lettuce, carrots & spinash. My challenge is not having enough space to grow all these bcos am now planning to plant sweetcorn, watermelon, spanspek or canrteloupe & pumpkin. I need mentorship & somyeone who can help with a land to lease or make partnership to expand business. Your advice & help will be much appreciated.
