I think you can plant before December during spring already, as soon as the danger of frost has passed. Also, if you are planting more than one variety, it is best to do so a few weeks apart so they don't mature at the same time, because they cross-polinate between species.

I only have a small home garden. I generally start planting my first batch around more d Sept and the every 6 to 8 weeks thereafter. If my first batch was planted in September , my sweet or green corn is harvested in Early Jan or Feb. I plant pumpkins in between the rows and when the corn is about shin high I interspace with climbing green been. The pumpkin protects the corn roots and the beans provide nitrogen.

What is the best sweet corn maize seed to plant? I want the one that can produce bigger corns.

I am in Australia and don't know the varieties you have available in South Africa. I would google search 'sweet corn seed' on your computer. There are three mail order seed companies that I am aware of in your country. They will have a range of sweet corn seed available and each will have details regarding colour, size and sweetness to choose from. I trust someone from your area will respond to your query with some suggestions. Trust this helps.

What season does the mealies get harvested in South Africa
02 May 17, John (Australia - temperate climate)
You would normally harvest mealies when the stalks and leaves have dried off. This would generally be in May but seasons do vary. If you harvest them before they are properly dry they may be susceptible to mould. Store your mealies in a dry, airy place.

Hi, Would you know where I can buy some white maize seeds in Cape Town? Do think they will grow here without any problems? Many thanks, Mario
