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 - 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.

Hi, I'm a single mum on a serous budget and only a small space in the courtyard. Am I able to grow sweetcorn in pots? Am I better off planting them in the garden? What size pots do I need ? I like gardening. I sometimes wonder if it's just cheaper to buy a $ 1 cob and be done with it! Thank you for the emails. I find them very helpful. Ingrid

Sweet corn will grow in large pots or tubs. It likes plenty of water and a good food supply (manure, compost, etc). 20 litre buckets may be obtained free from bakeries or fast food outlets. Drill some drainage holes in the bottom. Large planter tubs may also be availble from landscapers who plant advanced trees. With ample food and water you could try 2 or 3 plants per tub. To increase yield from that space plant 2 or 3 climbing bean seeds as well. they will climb up the corn stalks adding another vegetable to your harvest. It maybe too late to plant sweet corn this season but you could try salad greens (lettuce, bok choi, etc), carrots or beetroot. Not too much manure for the carrots or they will have forked roots. There is a huge variety of food that can be grown in small spaces and tests have shown that you can feed a family of 4 in the area of a double carport (6m x 6m). Keep going its great to grow your own healthy food. Trust this helps.
