If you want a crop that makes you feel suspiciously competent, Garlic is a beauty. You plant one clove and months later you pull up a whole bulb. It is productive, useful and deeply satisfying in a way only homegrown food can be.
For Australian gardeners, Garlic is mostly an Autumn job. Planting at the right time matters more than people realise and it is one of the main reasons some gardeners end up with fat, well-formed bulbs while others don’t.
If you have been wondering how to grow Garlic properly, this guide will walk you through the whole process, from planting to harvest.
Why Grow Garlic At Home?
Homegrown Garlic tastes better, stores well and does not need a huge amount of space. You can grow it in a vege patch, a raised bed or even a big pot if drainage is decent. It is also one of those crops that does not demand constant emotional support. Give it sun, decent soil and a bit of patience and it gets on with the job.
Another bonus is that once you get the hang of it, you can start saving your best bulbs for replanting the following Autumn. That is when you know you have crossed into proper Garlic-grower territory.
The Best Time To Plant Garlic In Australia
In most parts of Australia, Garlic is planted in Autumn. Early Autumn is often ideal, although local climate makes a difference. In cool to temperate areas, Autumn planting gives the plants time to establish well before Winter really bites. In warmer areas, choosing the right variety becomes even more important.
A simple rule of thumb is this:
| Climate Zone | Best Planting Window | Harvest Period |
|---|---|---|
| Cool to temperate (e.g. Melbourne, Hobart, Canberra) | March to May | November to January |
| Mild and warm (e.g. Sydney, Adelaide, Perth) | March to early April | October to December |
| Subtropical (e.g. Brisbane, northern NSW) | February to April (choose suitable varieties) | September to November |
| Arid inland (e.g. Alice Springs) | March to May | October to December |
| Tropical (e.g. Darwin) | April to May (choose subtropical/softneck varieties) | September to November |
It is worth noting that garlic can be tricky in tropical climates like Darwin. Garlic needs the transition from short day lengths in Winter to long day lengths in Summer to trigger bulb formation.
In tropical areas with less variation in day length, plants can produce plenty of green growth but smaller bulbs. Choosing softneck or subtropical varieties that are day-length neutral gives you the best chance of success in the Top End.
Choosing The Right Type Of Garlic
There are two main types of Garlic, hardneck and softneck. Hardneck Garlic is generally better suited to cooler climates and produces a flower stalk, called a scape. Softneck Garlic is usually better for temperate and warmer areas and tends to store for longer.
If you are buying Garlic to plant, look for bulbs sold specifically as planting Garlic. That means garden centres, growers, nurseries or reputable mail order suppliers. Supermarket Garlic can be hit and miss. It may have been treated with a growth inhibitor, may be imported and may simply not be well suited to your local climate.
Choose bulbs that are:
- firm and healthy
- free from mould and soft spots
- made up of large, plump cloves
- suited to your climate
Big cloves usually produce better bulbs, so save the scrappy little ones for cooking.
Preparing The Soil
If you want to know how to grow Garlic well, start with the soil. Garlic likes full sun, well-drained soil and plenty of organic matter. It hates sitting in wet ground, especially in heavy clay. If your soil holds water for ages after rain, fix that first or grow your Garlic in raised beds or pots.
Before planting, improve the bed with compost or well-rotted organic matter. Go easy on fresh manures and overly nitrogen-heavy fertilisers, as they can encourage soft leafy growth and increase the risk of rot. Garlic also prefers a fairly neutral to slightly alkaline pH.
A good Garlic bed should be:
- loose and friable
- rich in organic matter
- well-drained
- sunny for at least six hours a day
Companion Planting With Garlic
Garlic earns its keep in more ways than one. Along with giving you a useful crop, it is often included in companion planting because its strong scent may help confuse or deter some pests. Companion planting is not magic and it will not solve every garden problem, but it can be a handy part of a healthier, more balanced vege patch.
Garlic is often planted near Tomatoes, Carrots, Capsicums, Beetroot, Lettuce and Roses (true!). It is one of those plants that tends to fit neatly into a mixed garden bed, especially if you like growing a bit of everything rather than running your patch like a military operation.
There are a few pairings worth avoiding. Garlic and other Alliums are not usually recommended alongside peas and beans, so it is best to give legumes their own space. That way nobody is competing and your garden avoids unnecessary drama.
A simple approach is to plant Garlic around the edges of beds or tuck it between slower-growing crops where it can enjoy full sun and good airflow. Just do not cram it in too tightly. Garlic still needs room to bulb up properly and it will not thank you for being overly enthusiastic.
How To Plant Garlic
Break the bulb into individual cloves just before planting and leave the papery skins on. Pick the biggest and best cloves for planting and reject any that are bruised, soft or rotting. Plant each clove pointy end up and base down. Yes, orientation matters. Garlic is not a freestyle situation.
A reliable planting guide is:
- plant cloves 2 cm to 5 cm deep
- space them 10 cm to 15 cm apart
- allow enough room between rows for airflow and access
- water in well after planting
Mulching after planting is a smart move too. Straw or lucerne mulch helps retain moisture and suppress weeds, which is helpful because Garlic does not love competition. It wants to be the main character.
Can You Grow Garlic In Pots?
Yes, absolutely. Garlic grows very well in pots as long as the container is large enough and drains well. Use a quality potting mix and do not crowd the cloves. Stuffing too many into one container is a great way to grow a disappointing amount of tiny Garlic.
If you are setting up a Garlic patch or filling a few pots, our Garden Hand Tool Combo Pack is perfect for loosening soil, planting cloves and working compost through smaller beds without dragging out half the shed.
Watering And Feeding Garlic
Garlic likes consistent moisture while it is actively growing, especially once shoots appear and while the bulbs are swelling. The trick is to keep the soil moist, not wet. Overwatering is one of the fastest ways to head straight for rot. Water at the base rather than over the leaves, which helps reduce the risk of leaf disease.
Feeding can help too, especially once the leaves are up and growing strongly. If the bed is well prepared, Garlic may not need much extra at first, but feeding during active growth can encourage strong leafy growth and better bulb development.
A sensible routine looks like this:
- water in after planting
- keep the soil lightly moist once shoots appear
- feed during active growth
- avoid soggy soil
- ease off watering as harvest approaches
Should You Remove Garlic Scapes?
If you are growing hardneck Garlic, you may see curly flower stems called scapes appear before harvest. These are edible and very tasty but most gardeners remove them so the plant can direct more energy into forming the bulb.
Snip them off and cook them. Very satisfying. Nothing wasted.
Common Garlic Growing Mistakes
Garlic is fairly forgiving, but there are a few classic mistakes that can derail the whole thing.
- Planting At The Wrong Time – Timing affects bulb formation. Too early or too late can reduce clove development.
- Using Poor Planting Stock – Soft, damaged or supermarket bulbs can be unreliable. Use quality planting Garlic from a reputable source.
- Wet Soil – Garlic hates sitting in soggy ground and bulbs can rot in poorly drained soil.
- Not Enough Sun – Garlic needs a sunny spot, with at least six hours of direct sun a day.
- Harvesting Too Early – If the bulb has not separated into proper cloves yet, it is not ready. Leave the rest in for a bit longer and check again.
- Planting In The Same Spot Every Year – Avoid growing Garlic in the same soil year after year. Rotating crops helps reduce disease problems and gives the crop a cleaner start.
When To Harvest Garlic
This is the part where patience pays off. Garlic generally takes about six to eight months to mature, depending on the variety, when it was planted and your local conditions.
Signs your Garlic is ready include:
- leaves starting to yellow or brown
- tops bending or beginning to die back
- flower stalks bending on hardneck types
- bulbs feeling firm and properly formed
Do not wait until the entire plant is a crisp, tragic memory. If left too long, the bulb wrappers can split and storage life can suffer.
How To Harvest, Cure And Store Garlic
Harvest on a dry day if possible. Loosen the soil first, then gently lift the bulbs rather than hauling them out by brute force. Once lifted, keep the roots and tops attached initially and move the bulbs somewhere dry, shaded and airy.
For curing, hang the plants in bunches or lay them in a single layer somewhere dry, shaded and well ventilated, such as a shed, garage or covered patio. Avoid direct sun and anywhere damp or stuffy. The exact curing time depends on your climate and humidity but it usually takes around two to four weeks.
You will know the Garlic is cured when the outer skins feel dry and papery, the neck has dried out and tightened, and the roots look wiry rather than fresh and fleshy. The bulbs should feel firm, not soft and there should be no obvious moisture left in the stem.
If the neck still feels thick, greenish or slightly damp, it needs more time. Properly cured Garlic should look and feel dry all over before you trim the roots and tops for storage.
Once cured:
- Trim roots and tops if you like
- Brush off excess dirt
- Store in a cool, dry, well-ventilated spot
- Avoid sealed plastic bags
Softneck Garlic generally stores longer than hardneck types, which is one reason it is so popular in warmer parts of Australia.
Garlic Is One Of The Great Gateway Crops
Once you learn how to grow Garlic, it becomes one of those crops you keep planting year after year. It is useful, productive and oddly confidence-boosting. You put one clove in the ground and months later you pull out a whole bulb. That is a good deal by any measure.
Plant some this Autumn, keep the soil free-draining, do not drown it with love and future you will be in the garden harvesting bulbs like an absolute legend, already mentally halfway to a rustic pasta sauce, roast veg tray or homemade salsa made with garden-grown Garlic, Tomatoes and Capsicums.
While your Garlic is quietly getting on with the job underground, there is no reason the rest of your gardening life cannot be a bit more enjoyable. Our Garden Hand Tool Combo Pack is perfect for all the small but satisfying jobs, from planting cloves to tidying pots and poking about in the soil like the curious garden gremlin you are.
Pair it with our Activated Charcoal and Pumice Gardener’s Soap and you have the full before-and-after experience, grubby hands in the garden followed by a proper scrub once the dirt, compost and general evidence of your efforts have built up nicely.
FAQs – How To Grow Garlic
It is not recommended as supermarket garlic is often treated with sprouting inhibitors and imported bulbs are fumigated before entering Australia. For the best results, buy planting garlic from a nursery or garden centre.
Garlic typically takes six to eight months from planting to harvest, depending on the variety and your local climate.
This usually happens when garlic is harvested too early, planted too late in the season or grown from poor quality cloves. If the first bulb you lift has not separated into cloves, leave the rest in the ground for a few more weeks.
Yes, garlic grows well in pots as long as you use a container at least 30 cm wide and 20 cm deep with good drainage holes and a premium potting mix.
