Botanical Profile
Lemon myrtle, scientifically known as Backhousia citriodora, is a flowering tree native to subtropical rainforests of Queensland. You’ll recognise it by its elegant branches and fragrant, creamy autumn flowers.
In ideal conditions, lemon myrtle can grow up to 8 metres tall. However, you can easily keep it smaller in pots or gardens. The tree’s leaves are rich in citral, giving them their distinctive lemon scent.
You’ll find lemon myrtle thrives in most soil types, though it prefers well-drained conditions. It’s a hardy plant that responds well to slow-release fertilisers.
Historical Use
Indigenous Australians have long valued lemon myrtle for its medicinal properties. You might be surprised to learn they’ve used it for thousands of years to treat various ailments.
In modern times, lemon myrtle has gained popularity in the culinary world. You can use its leaves as a lemon substitute in both sweet and savoury dishes.
The plant’s essential oil is also widely used in aromatherapy and skincare products. You’ll find it in soaps, lotions, and even toothpaste, where it offers antibacterial benefits.
Cultivation and Harvesting
Lemon myrtle thrives in specific conditions and requires proper care to flourish. You’ll need to understand the ideal growing environment and farming practices to successfully cultivate this aromatic Australian native.
Growing Conditions
Lemon myrtle prefers full sun and well-drained soil. You’ll want to choose a spot that receives at least 6 hours of direct sunlight daily. The plant flourishes in subtropical climates but can adapt to cooler regions if protected from frost.
For potted lemon myrtle, select a large container with good drainage. Use a high-quality potting mix enriched with compost and well-aged manure.
In the garden, space your plants 5-10 metres apart to allow for their mature size. Lemon myrtle can reach heights of 20 metres in ideal conditions, so consider this when planning your garden layout.
Farming Practices
To get the best from your lemon myrtle, you’ll need to follow proper farming practices. Water your plants regularly, especially during dry spells. Mulching around the base helps retain moisture and suppress weeds.
Prune your lemon myrtle annually to maintain its shape and encourage bushier growth. This also makes harvesting easier. You can harvest the leaves year-round for culinary or aromatic uses.
Fertilise your plants in spring and autumn with a slow-release native plant fertiliser. Be cautious not to over-fertilise, as this can lead to excessive leaf growth at the expense of flavour.
Keep an eye out for pests like scale insects and mealybugs. If you spot any, treat them promptly with horticultural oil or insecticidal soap.

Environmental Impact
Lemon myrtle cultivation offers significant ecological benefits while presenting some important considerations. Its production aligns with sustainable practices and interacts closely with local ecosystems.
Sustainability Practices
Lemon myrtle is well-suited for sustainable commercial farming due to its native Australian origins. The plant thrives in the harsh Aussie climate, adapting to both drought and heavy rains.
This resilience reduces the need for intensive irrigation and chemical interventions, lowering your environmental footprint. Lemon myrtle farms often employ water-efficient techniques and minimal pesticide use.
Many growers adopt a no-waste approach, utilising all parts of the plant. Leaves are processed for oils and spices, while leftover material can be composted or used as mulch.
Ecosystem Considerations
As a native species, lemon myrtle supports local biodiversity. Your lemon myrtle plantation can provide habitat for native wildlife and pollinators.
However, it’s crucial to be aware of myrtle rust, a fungal disease affecting plants in the Myrtaceae family. This pathogen poses a significant threat to lemon myrtle and other native species.
To protect ecosystems, you should implement strict biosecurity measures on your farm. Regular monitoring for signs of myrtle rust and prompt action if detected are essential.
Responsible land management practices, such as maintaining wildlife corridors and preserving natural vegetation, can help balance commercial production with ecosystem health.
