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

Try a seed selling website.

Is the a particular variety of sweet corn I should plant in Zone 10b?

Not really, comes down to what kind of sweet corn you like. Or ask around local people who grow sweet corn in your area. I grow a bi-color variety in warm climates in Australia.

If you are zone 8a, click on Vegetables and Herbs tab, go to sweet corn and look it up. Set your zone at the top of the page. Check planting times and follow the suggested planting methods.

My 6-yr-old came home with an egg carton of sweetcorn seeds he'd planted at school. We put them on the windowsill and they've sprouted beautifully. But it's June, and although it's very mild now (in Waikato) we're expecting to get winter weather soon. He's very excited about these seedlings and would love to grow them to fruition - do you think I could grow them in a large pot as an indoor plant?

Corn needs to be planted in rows about 6-800mm apart. Seeds need to be planted about 150mm apart. Best to grow 2 or more rows together in a block for pollination. When the tassel and silks come out it takes about 5 days for pollination. Then about 21 days for cob to be ready to pick. Read up on the net.

Corn needs full sunlight to produce a good cob. If you fail this time try a more suitable time like spring summer to try again.

I think they transplant ok. They sell corn seedlings in seed trays at Bunnings.
