I have s quite a few PURPLE CORN which I grew a few years ago but over the last 2 years I have been unable to grow them again. Is there any information available about the best time an method to grow them in Sydney?. Thank you

Corn and maize do well if they have plenty of compost or manure and a good water supply. They can normally be planted as the weather warms up in spring. probably mid-September onwards in Sydney. You could also plant climbing beans to grow up the corn stalks once the corn has reached about waist high.

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!

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 - www.depi.vic.gov.au 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

When planting very small seedlings protect them with some shade for 5-7 days. Transplant seedlings when they are 75-100mm high. Seasol is not fertiliser, it is a soil conditioner. Go and buy some fertiliser (organic or chemical). Wait until the plants have grown to 150mm high then fert lightly. Do again a month later, this time use more fertiliser - read the instructions. Buy a 2-3 kg packet of fert. The little tubs of fert are a rip off. When growing corn plant 2-3-4 rows 600mm apart for pollination reasons. Corn needs lots of fert and water.
