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.

Usually crop rotation is done so diseases don't build up in the beds, and also because each type of crop takes different nutrients from the soil. Growing the same crop in the same spot all the time would deplete the soil. Legumes fix nitrogen in the soil, so growing leafy greens to follow would have them benefitting from the nitrogen. Hope this helps...

When i pick the corn of the plants do more corn keep growing or do i just get rid of the plants when all cobs picked

After a corn/maize plant has produced a cob or cobs it will not produce any more. You can cut the stalks off or pull them out of the ground and use them for mulch or plant climbing peas on them - free stakes! Trust this helps

I've had a problem with every corn stalk being chewed open about where the corn would growand also at other places. Im guessing this is by possums or rodents as some stalks are bent over. Anyone else had this issue and can suggest a solution?

Sounds very much like possums or rodents as the 'budding' cob would be very sweet and nutritious. Controlling them is a challenge. There are bark chips of the Quassia tree which should be available online. They can be soaked then boiled to make a very bitter tasting concoction that you spray on. This also works for wallabies on garden shrubs. The bitterness shouldn't affect the cobs as they are inside the husks. Trust this helps.

How can you freeze sweetcorn if you grow a lot of them, instead of just giving it all away?

I also just trim each end and freeze it, leaving the husks on the cobs before i bag them.

James, I love sweetcorn and grow heaps.Used to blanch it and vacumn seal then freeze for up to 12 months, now I just freeze. Still beautiful and sweet and lasts all year.

A more general question regarding crop rotation... I chose corn because I've seen several such discussions on this board. When you plant in rotation 'following' another crop... from where does the benefit come? Must I compost any leftover foliage of the previous crop and dig it back in to gain benefit? Or is there some other reason?
