Lemongrass is a fast-growing, low-maintenance plant that thrives in warm, sunny climates like Australia. It is a popular ingredient in Asian cooking and can be easily grown at home in pots or garden beds. Lemongrass is a perennial plant that can grow up to 1.5m tall and 0.8m wide and has a variety of uses, from cooking to essential oils and herbal remedies. In this article, we will explore the different ways to grow lemongrass in Australia and the ideal conditions for its growth.
| Characteristics | Values |
|---|---|
| Growth | Lemongrass grows well in all climate zones of Australia. In tropical, sub-tropical, and warm-temperate climates, it will grow as a perennial, therefore, all year round for a few years. |
| Height | Lemongrass can grow between 0.9-1.5 m tall and 0.8 m wide but can be trimmed to size as needed. |
| Soil | Lemongrass grows best in rich, well-drained soil with plenty of organic matter. It prefers a slightly acidic to neutral pH of 6.0-7.5 but can tolerate a pH range of 5.0-8.4. |
| Sunlight | Lemongrass thrives best in full sun. Ideally, it should receive 6-8 hours of sunlight daily. It can also grow in part shade as long as it gets direct sunlight for at least half the day. |
| Watering | Lemongrass is drought-tolerant but still needs water to thrive. Water the plant when the soil has fully dried out to prevent root rot. |
| Fertilizer | During the growing season, use a balanced, slow-release fertilizer with equal parts nitrogen, phosphorus, and potassium. You can also feed your lemongrass with organic liquid plant food every few weeks. |
| Pruning | Lemongrass requires regular pruning to keep it from overgrowing. It can be pruned back at the end of winter to encourage new growth in spring. |
| Harvesting | You can harvest lemongrass at any time of the year, but stalks will take longer to grow back in winter. Simply cut whatever leaf or stem is needed, being careful not to damage the growing points at the base of the plant. |
| Varieties | West Indian Lemongrass (Cymbopogon citratus) is the most commonly grown variety for cooking. East Indian Lemongrass (Cymbopogon flexuosus) has purple-tinged stems and is used for essential oils and herbal remedies. Australian Lemongrass (Cymbopogon ambiguus) is native to Australia and has a more delicate flavor. |

What You'll Learn
Lemongrass thrives in Australia's climate
Lemongrass is a low-maintenance plant that thrives in Australia's climate. It is a small clumping grass that grows to a maximum of 1 metre high, with thicker white stems producing bright green leaves. It is a perennial plant that can be propagated by splitting up a large clump or by division. It can also be grown from seeds, seedlings, or cuttings.
Lemongrass grows best in full sun, so it is important to place it in a warm and sunny position. It thrives in warm growing conditions and well-drained soil and is drought-tolerant, so it does not need much water. However, regular watering will encourage lush growth. It prefers a slightly acidic to neutral pH of 6.0-7.5 but can tolerate a pH range of 5.0-8.4. Before planting, improve the soil with compost or well-rotted manure.
Lemongrass can be grown in pots or garden beds, but it needs room to grow as it can spread widely. In tropical, subtropical, and arid regions, lemongrass will grow as a perennial, so it will last all year round for a few years. In cold climates, it is better to grow lemongrass in pots so that it can be moved indoors during winter to protect it from frost.
There are two common varieties of lemongrass: West Indian Lemongrass (Cymbopogon citratus) and East Indian Lemongrass (Cymbopogon flexuosus). West Indian Lemongrass is the most commonly grown variety and is commonly used in cooking. East Indian Lemongrass has purple-tinged stems and a stronger lemony scent, and it is often used for essential oils and herbal remedies. There is also an Australian native lemongrass called Cymbopogon ambiguus, which has finer growth.

Lemongrass can be grown from seeds, seedlings, cuttings or stem division
Lemongrass is a low-maintenance herb that can be grown in a variety of ways, including from seeds, seedlings, cuttings, or stem division. Here is some detailed information on each method:
Seeds
Lemongrass seeds can be purchased from larger garden centres or online seed suppliers. To grow lemongrass from seeds, sow them in small pots or modular trays in late winter or spring. Place the pots in a heated propagator or on a warm windowsill at 20–25°C (70–75°F). Keep the seedlings warm, well-watered, and in good light to ensure strong growth. Move them into slightly larger pots once the roots start to show through the holes in the base.
Seedlings
Seedlings refer to young lemongrass plants that have already been started from seeds. You can purchase these young plants and transplant them into your garden or pots. Keep in mind that lemongrass grows well in rich, well-drained soil, so improve your soil with organic matter if needed. Choose a sunny or partially shaded spot in your garden, and space the plants at least 30 cm (1 ft) apart. If growing in pots, choose a pot that is at least 30 cm (1 ft) wide and deep and fill it with a potting mix.
Cuttings
Cuttings involve taking a section of a stem from an existing lemongrass plant and rooting it to create a new plant. You can use store-bought lemongrass stalks or stems from your own plant for cuttings. To increase the chances of success, start with fresh lemongrass with the entire stem intact. Trim any brown, older leaves and cut off the stiff, topmost leaves. Place the cuttings in a jar or vase with a few inches of water and put them in a sunny location. Change the water regularly, and wait for new roots and leaves to emerge, which can take about a week. Once the roots are at least 3 inches long, plant the cuttings in a nutrient-rich bed of soil or potting mix.
Stem Division
Stem division involves dividing the clumps of an existing lemongrass plant to create new, separate plants. To do this, tip the plant out of its pot and use a sharp tool to cut the rootball into multiple pieces, ensuring each piece has a good set of roots and several strong stems. Then, replant each section into its own pot and water it well. This method is particularly useful for controlling the size of your lemongrass plant, as it can become wild and unruly if left unchecked.

Lemongrass grows best in rich, well-drained soil
Lemongrass is a tropical grass that is easy to grow and maintain. It is a herb that requires warm, humid conditions, full sunlight, and plenty of moisture. It is commonly grown as an annual in cooler areas. Lemongrass thrives in rich, well-drained soil with high nitrogen content. The soil should be slightly acidic to neutral, with a pH of between 6.0 and 7.5.
To create the ideal environment for lemongrass, you need a blend that retains moisture without becoming waterlogged. Before planting, improve the soil with organic matter, compost, or well-rotted manure. A layer of organic mulch, such as sugarcane or pea straw, can help retain soil moisture and suppress weeds.
The type of soil you use is important. A good base is high-quality potting soil, which provides structure and basic nutrients. Coarse sand or perlite can be added to ensure good drainage and prevent root rot. Worm castings are also an excellent source of nutrients and can improve soil structure.
If you are growing lemongrass in pots, use a quality potting mix and a large pot that is at least 300mm wide and deep to support a healthy root system. Potted plants may need to be watered daily and brought indoors during cold temperatures to protect them from frost.

Lemongrass can be grown in pots or garden beds
Lemongrass is a low-maintenance plant that can be grown in pots or garden beds. It is a tropical or subtropical perennial that thrives in warm, sunny climates like Australia.
When growing lemongrass in pots, choose a container that is at least 12 inches wide and deep, or a 5-gallon bucket, to support a healthy root system. Use a quality potting mix and place the container in a sunny or partially shaded spot in your garden. Lemongrass likes as much sun as possible, so give it 6-8 hours of sunlight daily. If you're growing it indoors, place it in a bright, south-facing window. Water potted lemongrass regularly, as it can dry out quickly, and feed it with a nitrogen-rich fertiliser or organic liquid plant food.
Lemongrass can also be grown in garden beds or directly in the ground. Improve the soil with plenty of organic matter, like compost or well-rotted manure, and ensure good drainage. Garden beds give lemongrass room to spread, but you'll need to prune regularly to keep it from overgrowing. Feed lemongrass with fertiliser a few times a year and water regularly until it is established. Once established, it is fairly drought-tolerant but will perform better if the soil is kept moist.
Lemongrass can be grown from seeds, seedlings, cuttings, or stem division. It is easy to propagate lemongrass in water by placing a stalk in a glass of water with the bulb facing downward. Change the water every few days and once roots have emerged, transplant the stalk into soil.
