No Richard, that is not the growing season for garlic. People plant the cloves in April to June. We normally harvest around November to December. The old farmers used to say plant on the shortest day (June 21) harvest longest day (December 21).

Leontine, I second what Abbie said. I've tried to grow supermarket garlic. When it was cheap imported garlic it just rotted in the ground. Local stuff, when available, grew ok.

You might not be able to plant the garlic from the supermarket depending on where it has come from. Most imported stuff is sprayed with all sorts of toxins, and many are sprayed with various growth inhibitors. Try getting some Australian garlic, or even better some organic garlic. Otherwise, try diggers.com.au as they have garlic for sale online.

So when it says plant garlic cloves, you can just break up and plant the individual cloves that you get from the supermarket?

Garlic has a long growing season. The old saying "Plant on the shortest day and dig on the longest day" is the easiest way to remember how long. If it is planted in good soil you won't need to fertilize it. In the hot months water regularly, it doesn't like long dry periods.

Can someone please supply a set of rules for growing garlic. I've not grown it before. My garlic has just shot and is looking healthy but I don't know if I have to fertilize or not, nor do I know how much water to give it
