Best Herbs To Grow In Australia

British Columbia’s rainy coastal areas excel with water-loving herbs like mint, lovage, and watercress. But if you’re gardening in Australia, your climate is a whole different story. Finding the best herbs to grow in australia means picking plants that can handle heat, drought, and sometimes poor soil. You don’t need a green thumb to succeed—just the right choices and a bit of know-how.

Australia’s diverse climate zones, from tropical north to temperate south, offer unique opportunities for herb gardening. The key is matching your herb selection to your local conditions. Whether you’re in Sydney’s humid summers or Perth’s dry heat, there’s a herb that will thrive in your patch.

This section covers the top performers for Australian gardens. These herbs are tough, productive, and useful in the kitchen. They handle our variable weather and need minimal fuss.

Basil

Basil loves heat. It grows fast in summer and gives you leaves for months. Plant it after the last frost in spring. In tropical areas, you can grow it year-round.

Choose sweet basil for pesto
Try Thai basil for stir-fries
Pinch off flowers to keep leaves coming
Water at the base to avoid leaf diseases

Mint

Mint is almost too easy. It spreads like crazy, so grow it in a pot or a contained bed. It likes partial shade and regular water. Perfect for teas and salads.

Spearmint and peppermint are popular
Keep it contained or it will take over
Harvest often to encourage bushy growth
It grows well in most Australian climates

Rosemary

Rosemary is a drought-tolerant champion. It thrives in poor soil and full sun. Once established, it needs little water. Use it for roasting meats or as a hedge.

Plant in well-drained soil
Prune after flowering to keep shape
It handles coastal conditions well
Great for Mediterranean-style gardens

Thyme

Thyme is another sun-lover. It stays low and spreads nicely. It’s perfect for rockeries or between paving stones. The leaves add flavor to stews and soups.

Common thyme and lemon thyme are best
It needs good drainage
Cut back after flowering to refresh
It’s very drought-tolerant once established

Chives

Chives are easy and productive. They grow in clumps and come back every year. Use the leaves in salads or as a garnish. They also have pretty purple flowers.

Plant in full sun or light shade
Divide clumps every few years
Water regularly but don’t overdo it
They grow well in pots or garden beds

Parsley

Parsley is a biennial, meaning it lives for two years. It prefers cooler weather but can handle some heat. Flat-leaf and curly types are both useful.

Sow seeds directly in the garden
Soak seeds overnight before planting
Harvest outer leaves first
It needs regular water and partial shade in hot areas

Coriander (Cilantro)

Coriander is tricky because it bolts quickly in heat. Grow it in cooler months or partial shade. Use both leaves and seeds in cooking.

Sow seeds every few weeks for continuous harvest
Let some plants go to seed for coriander spice
It grows best in spring and autumn
Water consistently to delay bolting

Lemon Balm

Lemon balm is a mint relative with a citrus scent. It’s easy to grow and attracts bees. Use it in teas or as a calming herb.

Grows in sun or partial shade
Keep it contained like mint
Harvest leaves regularly
It’s great for beginners

Oregano

Oregano is a hardy perennial that loves sun. It’s a staple in Italian cooking. The flavor gets stronger after flowering.

Greek oregano is the most flavorful

Sage

Sage is a woody shrub that handles heat and dry conditions. It’s great for stuffing and meat dishes. The leaves have a strong, earthy flavor.

Plant in full sun
Prune lightly after flowering
It needs good drainage
Replace plants every few years as they get woody

Climate Considerations For Herb Gardening In Australia

Australia has several climate zones. Your location determines which herbs grow best. Understanding your zone helps you avoid disappointment.

Tropical North

In places like Darwin and Cairns, it’s hot and humid year-round. Many Mediterranean herbs struggle here. Focus on heat-tolerant varieties.

Grow basil, mint, and lemongrass
Use shade cloth for sensitive plants
Plant in raised beds for drainage
Watch for fungal diseases in wet season

Subtropical And Coastal

Sydney, Brisbane, and Perth have mild winters and warm summers. Most herbs do well here. Just watch for humidity issues in summer.

Rosemary and thyme thrive
Parsley and chives grow year-round
Use mulch to keep roots cool
Water in the morning to prevent mildew

Temperate South

Melbourne, Adelaide, and Hobart have cooler winters. Herbs like mint and parsley love this. You’ll get a longer growing season for cool-season herbs.

Grow coriander in spring and autumn
Protect tender herbs from frost
Use cloches or cold frames in winter
Plant in full sun for best growth

Arid And Semi-Arid

Inland areas like Alice Springs are hot and dry. Water conservation is key. Choose drought-tolerant herbs.

Rosemary, sage, and thyme are ideal
Use drip irrigation to save water
Mulch heavily to retain moisture
Plant in partial shade if possible

Soil Preparation And Planting Tips

Good soil is the foundation of a successful herb garden. Most herbs prefer well-drained soil with moderate fertility. You don’t need rich soil—many herbs actually prefer lean conditions.

Improving Drainage

Australian soils can be heavy clay or sandy. Both need amending. Add organic matter like compost to improve structure.

Dig in compost or well-rotted manure
For clay soil, add gypsum to break it up
For sandy soil, add organic matter to hold moisture
Raised beds help with drainage in wet areas

Testing Ph Levels

Most herbs prefer neutral to slightly alkaline soil. Test your soil pH with a simple kit. Adjust if needed.

Add lime to raise pH in acidic soil
Add sulfur to lower pH in alkaline soil
Aim for pH 6.0 to 7.5
Herbs like lavender prefer alkaline conditions

Planting From Seed Vs Seedlings

Seeds are cheaper but take longer. Seedlings give you a head start. Choose based on your patience and budget.

Basil and coriander grow easily from seed
Rosemary and sage are better from seedlings
Sow seeds in punnets or direct in garden
Transplant seedlings on a cloudy day to reduce shock

Watering And Maintenance

Herbs need consistent water, especially when young. Once established, many are drought-tolerant. Overwatering is a common mistake.

Watering Schedule

Water deeply but infrequently. This encourages deep roots. Adjust based on weather and soil type.

Water in the morning to reduce evaporation
Check soil moisture with your finger
Use drip irrigation for efficiency
Reduce watering in winter

Fertilizing

Herbs don’t need heavy feeding. Too much fertilizer reduces flavor. Use a balanced, slow-release fertilizer sparingly.

Apply compost tea monthly
Avoid high-nitrogen fertilizers
Feed leafy herbs like basil more often
Stop fertilizing in late autumn

Pruning And Harvesting

Regular harvesting keeps herbs bushy and productive. Always cut above a leaf node. Never take more than one-third of the plant at once.

Harvest in the morning after dew dries
Use sharp scissors or pruners
Pinch off flower buds to extend leaf production
Leave some flowers for pollinators

Common Pests And Diseases

Herbs are generally pest-resistant, but problems can occur. Early detection is key. Use natural methods first.

Aphids

These small insects cluster on new growth. They suck sap and attract ants. Wash them off with water or use insecticidal soap.

Check undersides of leaves regularly
Encourage ladybugs and lacewings
Neem oil is effective
Remove heavily infested leaves

Slugs And Snails

These pests love moist conditions. They chew holes in leaves. Use beer traps or copper tape around pots.

Hand-pick at night
Use crushed eggshells as a barrier
Avoid overwatering
Keep garden debris clean

Powdery Mildew

This fungal disease appears as white powder on leaves. It’s common in humid conditions. Improve air circulation and avoid wetting leaves.

Space plants properly
Water at soil level
Remove affected leaves
Use a baking soda spray as treatment

Companion Planting With Herbs

Herbs can benefit other plants in your garden. They repel pests, attract pollinators, and improve soil health. Use them strategically.

Herbs That Repel Pests

Some herbs have strong scents that deter insects. Plant them near vulnerable vegetables.

Basil repels tomato hornworms
Mint deters ants and aphids
Rosemary repels carrot flies
Thyme confuses cabbage moths

Herbs That Attract Beneficial Insects

Flowering herbs bring in bees, butterflies, and predatory insects. This helps pollination and pest control.

Dill attracts ladybugs
Fennel draws hoverflies
Coriander flowers attract parasitic wasps
Lavender brings bees

Herbs As Ground Cover

Low-growing herbs can suppress weeds and retain soil moisture. They also look attractive.

Thyme works well between stepping stones
Oregano spreads as a ground cover
Chamomile forms a soft mat
Mint is too aggressive for most areas

Harvesting And Storing Herbs

Proper harvesting and storage extend the life of your herbs. You can enjoy fresh flavors year-round with simple techniques.

Fresh Storage

Keep herbs fresh longer with these methods. Treat them like cut flowers or store them in the fridge.

Place stems in a glass of water on the counter
Wrap in damp paper towel in the fridge
Use herb keepers with water reservoirs
Change water every few days

Drying Herbs

Drying concentrates flavors. It’s easy to do at home. Use dried herbs within a year for best taste.

Harvest in the morning after dew dries
Bundle stems and hang upside down
Keep in a dark, well-ventilated area
Store in airtight jars once dry

Freezing Herbs

Freezing preserves fresh flavor. It’s great for soft herbs like basil and mint. Use within six months.

Chop herbs and place in ice cube trays
Cover with water or olive oil
Freeze and transfer to bags
Add cubes directly to cooking

Making Herb Oils And Vinegars

Infused oils and vinegars are easy to make. They add flavor to salads and marinades. Use clean, dry herbs to prevent spoilage.

Use extra virgin olive oil for herbs
Use white wine vinegar for delicate flavors
Store in cool, dark place
Refrigerate and use within a month

Seasonal Herb Gardening Calendar

Knowing when to plant and harvest helps you plan. Australia’s seasons are opposite to the Northern Hemisphere. Adjust accordingly.

Spring (September To November)

Spring is the main planting season. Soil warms up and growth accelerates. Plant most herbs now.

Sow basil, coriander, and parsley
Plant seedlings of rosemary and thyme
Divide chives and mint
Start fertilizing monthly

Summer (December To February)

Summer is peak growth for heat-lovers. Harvest regularly to keep plants productive. Watch for pests and heat stress.

Harvest basil and mint weekly
Provide shade for sensitive herbs
Water deeply in the morning
Mulch to keep roots cool

Autumn (March To May)

Autumn is for planting cool-season herbs. It’s also time to prepare for winter. Reduce watering and stop fertilizing.

Sow coriander and parsley
Plant garlic chives
Cut back perennial herbs
Clean up dead plant material

Winter (June To August)

Winter growth slows down. Protect tender herbs from frost. Focus on harvesting hardy varieties.

Harvest rosemary and thyme sparingly
Cover basil and coriander if frost expected
Move potted herbs to sheltered spots
Plan next season’s garden

Container Herb Gardening For Small Spaces

Not everyone has a garden. Herbs grow well in pots on balconies, patios, or windowsills. Choose the right containers and soil.

Choosing Pots

Drainage is critical. Use pots with holes at the bottom. Terracotta pots dry out faster but look nice.

Use at least 20cm diameter pots
Larger pots hold moisture longer
Use saucers to catch water
Lift pots on bricks for airflow

Potting Mix

Use a quality potting mix designed for containers. Add perlite or sand for drainage. Avoid garden soil in pots.

Choose a mix with slow-release fertilizer
Add water-retaining crystals in hot areas
Replace mix every year or two
Top up with fresh mix as needed

Best Herbs For Pots

Some herbs adapt better to containers than others. Choose compact varieties for best results.

Basil, chives, and parsley are ideal
Mint needs a large pot to spread
Thyme and oregano stay small
Rosemary can outgrow small pots
