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.

We live in suburbs in Chatswood Sydney but as soon as the cobs form a rabbit turns up and eats all the corn (also the chillies).

The rabbit stew sounds like a great idea!

Max, Best trap the rabbit and enjoy a rabbit and vege stew.

Rabbits, possums, etc can be a real menace with our vegetables. Multicrop have a product call 'Scat' which is supposed to provide protection for up to 10 weeks. I haven't used it but have used other products from the same company and found them to be safe and effective. It is available at Bunnings but should be available from other hardware stores and garden centres. the DEPI in Victoria, Dept Env. Land and Water have a number of solutions to the problem. Look up - and search for possum repellants. Their recipe using Quassia chips has been around for many years. Trust this helps.

Hi Mark Southcombe About the ants. While I have a lot of ants they are not a problem now that I am using a Bokashi system of compost. In fact no bugs are attacking my vegetables. I am growing corn for the first time and so far so good. I will keep an eye on all the things mentioned in this post.

Hi There! I was wondering how I can get rid of the little black ants that are eating and nesting in my sweet corn. And something is eating away my capsicum........... Thank you

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.
