  • Easy to grow. Plant cloves. Best planted at soil temperatures between 10°C and 35°C. (Show °F/in)
  • Space plants: 10 - 12 cm apart
  • Harvest in 17-25 weeks.
  • Compatible with (can grow in same bed): Beets, Carrots, Cucumbers, Dill, Tomatoes, Parsnips
  • Avoid growing in same bed: Asparagus, Beans, Brassicas, Peas, Potatoes

Garlic is traditionally planted in cold weather and harvest in summer ("plant on the shortest day, harvest on the longest"). Plant the cloves (separated from the bulb), point upwards, deep enough to just cover with soil. A fairly tough and easy-growing plant. On better soil with regular watering you will get a better crop. On poorer soil, and forgetting to water them, you will still get some garlic, only not quite so much.

Leave a garlic to go to seed, and you will probably get plenty of self-sown plants the following year.

To keep for later use, dig up and leave to dry out for a day or so after the green shoots die down. To use immediately, pull up a head when you need it, or cut and use the green shoots.

Culinary hints - cooking and eating Garlic

Cut the growing shoots or use the entire young garlic plants as 'garlic greens' in stirfry.

I am in Sydney, When will be good time to grow garlic ?

Hi I have tried growing garlic a couple of times now. Generally I plant on the 23 March and harvest 23 June. First few times garlic was small except for a couple decent sized ones. Last year, I ended up with one large bulb only, on each plant; almost like a small onion. What would cause this to happen?

Hi Dianne I am in a sub tropical area too and I plant late April/May and harvest in November when leaves start to die down. Perhaps you are harvesting to early?

The easiest way to get garlic is to buy it from a green grocer (fruit shop) or nursery and separate the cloves before planting. one garlic bulb will yield 8 - 12 cloves. Seed is often available from seed companies, nurseries or garden centres. Refer to the Vegetables & Herbs guide on this site for more planting information. Happy garlic growing!

Can I just grow garlic and store for more than 6 weeks?

When the tops die off garlic is ready for harvest. If you hang it in a dry airy place it will keep for months. You can use some of the cloves to gro your next crop. Trust this helps.

This is a transcript of a article on growing garlic in central Australia (desert). It is on ABC Rural News and may be a help to you. Trials reveal potential for garlic-growing in Northern Territory Posted 7 Oct 2016 MAP: Alice Springs 0870 A trial exploring the capabilities of seven garlic varieties in the red centre is showing some early positive results. Seven varieties of garlic are being trialled at the Northern Territory's Arid Zone Research Institute (AZRI), alongside the standard industry garlic variety, Glen Large. The Alice Springs environment will demonstrate how varieties that have never been grown commercially in the Northern Territory respond to extreme cold and extreme heat. Central Australian Horticulture Development Project manager and researcher Stuart Smith said despite challenges such as poor water quality, the results so far had been positive. "We're hoping, because we're just south of the Tropic of Capricorn, we're just a bit a little subtropical, that we're in the right area," he said. "We've got the right heat profile, right day length and we're able to grow some good bulbs. "If it'll grow here, it'll grow anywhere. "Central Australia is a bit isolated from the rest of Australia so it doesn't have the pests and diseases of the other garlic-growing areas." Plan to get garlic onto market early in season Mr Smith believes there is a market opportunity for garlic that grows early in the traditional growing season. We thought we could get a few varieties to come early on the market, so we can get some good prices for them and replace the imported garlic," he said. The first successful harvested trial crop has reached a stage of maturity that would be ready for market. "It's got a code name called AF. We're getting some good-sized bulbs out of this," Mr Smith said. "I estimate we're getting 6-8 tonnes per hectare."

(ABC Rural: Katrina Beaven) Mr Smith said the early trial results were encouraging despite poor water quality and salty soils. "We have to keep watering them pretty constantly to keep moving the salt out of the root zone," he said. "The water we're using at AZRI is pretty low quality. "Most of the water other people are using in horticulture around the Central Australian region is a lot better quality than this." Mr Smith said the research results would also add value to what was being learned by a grower at Orange Creek Station, south of Alice Springs, who is conducting a commercial garlic trial this year.

Hi, I was wanting to grow garlic on the Atherton Tablelands, some 800m above sea level, in the tropics. We have a subtropical to temperate climate. Which garlic would be best suited to our conditions? Thanks
