Jan..to keep birds away from cobs slip a plastic bag or stocking foot over the cob....problem solved

Why does my sweetcorn end up with no kernals on the cob. I prepared the soil with organic pellets and chicken manure but didn't have any luck.

Sounds like they weren't pollinated

Can you get coloured sweet corn in Australia? If so, where? They have heaps of types overseas, but the only coloured types I can find in Australia are not sweet corn.

Yes you can get diffrent colours, try ebay (check the seller is in Australia). I'm growing Inca purple corn that I bought from a local market... It's huge, I'm so excited!

There are several varieties of coloured sweet corns available in Australia, please never buy them from ebay as you will rarely get what you order. Google search

Perhaps they haven't been pollinated enough or gotten enough water.

I'd like to know how to dry the corn - it'd be good to have it on the cob for convenience. Some internet advice includes drying in the oven for extended periods of time. Can it be air dried?

Ants can be a problem in the garden. You don't say in your note how many plants you have but if it is only a few you could smear a band of petroleum jelly around each stalk to trap them. Ants are also deterred by pepper. Buy some cheap pepper and sprinkle it liberally around the plants. this works well to stop ants stealing carrot seed, which they love. Regarding the ones that are nesting I don't have any suggestions. Maybe a small amount of kitchen washing up liquid mixed with water and sprayed onto the affected plants will suffocate them. Regarding chewing pests on your capsicums. Yates 'Natures Way' is a very saafe spray to use for caterpillars. I don't use synthetic sprays or chemicals in my garden. Trust this helps.
