How to Grow Lemongrass in Australia

Lemongrass, scientifically called Cymbopogon, belongs to the grass family and is known for its distinct lemony fragrance and citrusy flavour. It boasts long, slender green leaves that grow in clumps and can reach a height of up to three feet. This aromatic herb is commonly used in Asian cuisine, particularly Thai, Vietnamese, and Indonesian dishes, where it adds a refreshing and tangy note to soups, curries, stir-fries, and marinades. 

Getting Started with Lemongrass

When it comes to getting started with growing lemongrass, there are a few key factors to consider. From choosing the right variety to understanding the soil and sun requirements, this section will guide you through the initial steps of cultivating this aromatic herb.

Choosing the Right Variety

Lemongrass comes in various varieties, and selecting the right one for your garden is essential. Some popular choices include Cymbopogon citratus, Cymbopogon flexuosus, and Cymbopogon winterianus. Each variety has its unique characteristics, such as flavour, growth habits, and tolerance to cold weather.

If you live in a region with a colder climate, it's advisable to choose a variety that is more cold-tolerant, like Cymbopogon winterianus. On the other hand, if you're looking for a lemongrass variety with a stronger flavour, Cymbopogon flexuosus might be the perfect pick.

Soil and Sun Requirements

Lemongrass thrives in well-draining soil that is rich in organic matter. It prefers a slightly acidic to neutral pH level, ideally ranging from 5.5 to 7.0. Before planting, ensure the soil is loose and loamy, providing excellent drainage for the roots.

When it comes to sunlight, lemongrass is a sun-loving herb. It requires full sun to grow vigorously and produce the best flavour. Make sure to choose a location in your garden that receives at least six to eight hours of direct sunlight each day.

Planting Techniques

To plant lemongrass, start by preparing the planting area. Dig a hole that is twice the size of the root ball of the lemongrass plant. Gently loosen the soil at the bottom of the hole to encourage root growth.

Next, place the lemongrass plant into the hole, ensuring that the crown of the plant is level with the soil surface. Fill the hole with soil, gently pressing it around the base of the plant to secure it in place. Avoid compacting the soil too tightly, as it can hinder root development.

If you're growing lemongrass from seeds, sow them in a seed tray filled with a well-draining seed-starting mix. Keep the soil consistently moist and provide warmth and light for germination.

Watering and Fertilising

Proper watering is crucial for the success of your lemongrass plants. Water deeply and infrequently, allowing the top few inches of soil to dry out between watering sessions. It's important to strike a balance and avoid both overwatering, which can lead to root rot, and underwatering, which can cause the plant to wilt.

As for fertilising, lemongrass benefits from regular feedings with a balanced organic fertiliser. Apply the fertiliser according to the manufacturer's instructions, typically every four to six weeks during the growing season. This helps provide the necessary nutrients for healthy growth and abundant harvests.

With these getting started tips in mind, you're well on your way to cultivating your very own lemongrass garden. Remember to choose the right variety, ensure proper soil and sun conditions, follow the correct planting techniques, and provide adequate water and fertiliser. Soon enough, you'll be enjoying the fresh and zesty flavours of lemongrass in your culinary creations or homemade natural remedies.

Caring for Your Lemongrass Plant

Once you have successfully planted your lemongrass, it's essential to provide proper care to ensure its health and vitality. Caring for your lemongrass plant involves a combination of pruning and harvesting, managing pests and diseases, and overwintering techniques.

Pruning and Harvesting

Pruning is an essential aspect of lemongrass care that promotes healthy growth and prevents the plant from becoming overgrown. Regular pruning helps maintain the desired size and shape of your lemongrass plant. It also encourages the production of fresh and flavorful stalks.

To prune your lemongrass, start by removing any damaged or dead leaves. Trim the stalks to about 6 inches above the ground, cutting just above the node where new growth emerges. This will encourage the development of multiple stalks and prevent the plant from becoming top-heavy.

Harvesting lemongrass is a delightful reward for your gardening efforts. The best time to harvest is when the stalks reach a height of around 12-18 inches and have a diameter of at least half an inch. Using a sharp knife or a pair of garden shears, cut the stalks at ground level.

Remember to only harvest what you need, allowing the remaining stalks to continue growing and replenishing the plant.

Pests and Diseases

While lemongrass is generally a hardy plant, it can still fall victim to a few pests and diseases. Common pests that may affect lemongrass include aphids, mealybugs, and spider mites. To control these pests, you can use natural remedies such as neem oil or insecticidal soap.

Additionally, keeping your lemongrass plant healthy and well-maintained can help prevent pest infestations. Regularly inspect the leaves and stalks for any signs of damage or pests and take appropriate action if necessary.

In terms of diseases, lemongrass is relatively resistant. However, it can occasionally be susceptible to fungal infections, such as leaf blight or rust. To prevent the spread of diseases, ensure that your lemongrass plant has good air circulation and avoid overwatering.


Overwintering is a crucial step in caring for lemongrass if you live in a region with cold winters. Lemongrass is a tropical plant that thrives in warm climates, so it requires protection during the colder months.

Before the first frost, dig up your lemongrass plant carefully, ensuring that you preserve the root system. Trim the foliage to about 6 inches above the ground, and then place the plant in a pot filled with well-draining soil.

Keep the potted lemongrass indoors in a sunny location with temperatures between 50-70°F (10-21°C). Water sparingly during winter, allowing the soil to dry out slightly between waterings.

By providing the necessary care, pruning and harvesting at the appropriate times, managing pests and diseases, and implementing effective overwintering techniques, you can enjoy a thriving and productive lemongrass plant in your home garden.
