Popular Basil Types in Australia
Here's a look at some of the most popular basil varieties you can grow in your Australian garden:
- Sweet Basil: This is the classic Italian basil with a sweet, slightly peppery flavor. It's perfect for pesto, pasta sauces, and salads.
- Genovese Basil: A type of sweet basil known for its large, slightly cupped leaves, it's the go-to choice for authentic pesto.
- Thai Basil: Characterized by its anise-like flavor and sturdy, purple-tinged stems, Thai basil is a must-have for Southeast Asian cuisine.
- Lemon Basil: As the name suggests, this variety has a distinct lemon aroma and flavor, adding a citrusy twist to dishes and drinks.
- Purple Basil: With its striking dark purple leaves, purple basil not only adds flavor but also visual appeal to your garden and dishes. It has a slightly spicier flavor than sweet basil.
- Globe Basil: Also known as Dwarf Basil, it grows in a compact, rounded shape, making it ideal for containers and small spaces. The flavor is similar to sweet basil.
Considering Your Climate
Australia's climate ranges from tropical in the north to temperate in the south. Here’s how different basil varieties fare across different zones:
- Tropical (North Queensland, Northern Territory): Thai basil and lemon basil thrive in the warm, humid conditions. Sweet basil can also be grown with adequate watering and protection from the intense sun.
- Subtropical (Southeast Queensland, Northern NSW): All basil varieties generally do well, but provide afternoon shade during the hottest months.
- Temperate (Victoria, Tasmania, Southern NSW, South Australia): Sweet basil, Genovese basil, and globe basil are good choices. Start seeds indoors in early spring to get a head start. Protect plants from frost.
- Arid/Semi-Arid (Central Australia, Western Australia): Basil can be challenging to grow due to the dry conditions and intense heat. Choose a sheltered location, provide regular watering, and consider growing in pots to control soil conditions.
Planting and Growing Basil in Australia: A Step-by-Step Guide
Now that you've chosen your variety, it's time to get planting! This section will cover everything you need to know about planting basil in Australia.
Starting from Seed vs. Seedlings
You can start basil from seed or purchase seedlings from a garden center. Both methods have their advantages:
- Seeds: More economical and offer a wider variety of choices. However, they require more time and attention.
- Seedlings: Provide a faster start and are easier for beginners.
Sowing Seeds Indoors
In cooler climates, starting seeds indoors is recommended to get a head start on the growing season. Here's how:
- Prepare Seed Trays: Fill seed trays with a good quality seed-starting mix.
- Sow Seeds: Sow seeds thinly on the surface of the soil and lightly cover with more mix.
- Water Gently: Water with a gentle spray to avoid disturbing the seeds.
- Provide Warmth and Light: Place the trays in a warm, sunny location or under grow lights.
- Keep Moist: Keep the soil consistently moist but not waterlogged.
- Transplant: Once the seedlings have developed a few sets of true leaves, they can be transplanted into larger pots or directly into the garden.
Planting Basil in the Garden
Whether you started from seed or purchased seedlings, here's how to plant basil in the garden:
- Choose a Sunny Location: Basil requires at least 6-8 hours of sunlight per day.
- Prepare the Soil: Basil prefers well-drained soil rich in organic matter. Amend the soil with compost or aged manure before planting.
- Plant Seedlings: Space seedlings 20-30cm apart.
- Water Thoroughly: Water the newly planted seedlings thoroughly.
- Mulch: Apply a layer of mulch around the plants to help retain moisture and suppress weeds.

Watering
Basil needs consistent moisture, especially during hot weather. Water deeply and regularly, but avoid overwatering, which can lead to root rot. Check the soil moisture regularly and water when the top inch feels dry.
Fertilizing
Basil benefits from regular feeding with a balanced fertilizer. Apply fertilizer every 2-3 weeks during the growing season. You can use a liquid fertilizer or a slow-release granular fertilizer. Organic options like compost tea or fish emulsion are also excellent choices.
Pruning
Pruning is essential for encouraging bushier growth and preventing basil from flowering. Once basil starts to flower, the leaves become bitter. Pinch off the flower buds as soon as they appear. Regularly harvest leaves by pinching or cutting them off just above a leaf node. This encourages new growth.
Pest and Disease Control
Basil is generally pest and disease-resistant, but it can be susceptible to certain problems:
- Aphids: Small, sap-sucking insects that can weaken plants. Control aphids by spraying them with a strong stream of water or using insecticidal soap.
- Slugs and Snails: These pests can damage basil leaves, especially seedlings. Use slug and snail bait or handpick them from the plants.
- Downy Mildew: A fungal disease that causes yellowing and browning of leaves. Improve air circulation around the plants and avoid overhead watering to prevent downy mildew.
Harvesting and Storing Basil
Knowing when and how to harvest and store basil is essential to enjoy its fresh flavor for as long as possible.
When to Harvest
Harvest basil leaves as needed throughout the growing season. The best time to harvest is in the morning, after the dew has dried. Avoid harvesting more than one-third of the plant at a time.
How to Harvest
Pinch or cut off the leaves just above a leaf node. This encourages new growth and keeps the plant bushy. For larger harvests, you can cut entire stems and strip off the leaves.
Storing Basil
Basil is best used fresh, but it can be stored in a few ways:
- Refrigeration: Wrap basil leaves in a damp paper towel and store them in a plastic bag in the refrigerator for a few days.
- Freezing: Blanch basil leaves in boiling water for a few seconds, then plunge them into ice water. Drain well and freeze in freezer bags or ice cube trays.
- Drying: Dry basil leaves by hanging them upside down in a cool, dark, and well-ventilated place. Once dried, store them in an airtight container.
- Basil Pesto: Blend fresh basil with olive oil, garlic, pine nuts, and Parmesan cheese to make pesto, which can be frozen for later use.
Troubleshooting Common Basil Growing Problems
Even with the best care, you may encounter some challenges when growing basil. Here are some common problems and how to fix them:
Yellowing Leaves
Yellowing leaves can be caused by overwatering, underwatering, nutrient deficiencies, or disease. Check the soil moisture and adjust watering accordingly. Fertilize the plants with a balanced fertilizer. Inspect the leaves for signs of disease and treat as needed.
Leggy Growth
Leggy growth is usually caused by insufficient sunlight. Move the plants to a sunnier location or supplement with grow lights. Pinch off the top growth to encourage bushier growth.
Lack of Flavor
Lack of flavor can be caused by poor soil, overwatering, or allowing the plant to flower. Ensure the soil is rich in organic matter and well-drained. Avoid overwatering and pinch off flower buds as soon as they appear.
Bolting (Flowering)
Bolting is a natural process that occurs when basil plants are stressed by heat or drought. Pinch off flower buds regularly to prolong the harvest. Provide consistent watering and afternoon shade during hot weather.
