Growing Mustard Greens in Australia

If you're an organic gardener in Australia, growing mustard greens can be a rewarding and delicious addition to your home garden. Mustard greens are versatile leafy vegetables with a spicy kick, perfect for adding flavour and nutrients to your meals. In this section, we will explore the climate and soil requirements for growing mustard greens, as well as the importance of choosing the right variety.

Climate and Soil Requirements

Mustard greens thrive in cool to warm weather, making them well-suited for many regions in Australia. They prefer temperatures between 15°C to 25°C (59°F to 77°F) for optimal growth. It's important to note that mustard greens are sensitive to extreme heat, so providing some shade during the hottest parts of the day can help prevent bolting (premature flowering).

When it comes to soil, mustard greens prefer well-draining soil that is rich in organic matter. Before planting, ensure the soil is loose and crumbly. If your soil is heavy or compacted, consider adding compost or well-rotted manure to improve its texture and fertility. A soil pH between 6.0 and 7.5 is ideal for mustard greens.

Choosing the Right Variety

When selecting mustard greens for your garden, there are several varieties to choose from, each with its own unique flavor and appearance. Some popular varieties in Australia include:

Variety Name


Green Wave

This variety has deeply serrated leaves and a vibrant green color. It offers a mild, mustard-like flavour.

Red Giant

With its large, deep red leaves, this variety adds a pop of colour to your garden and dishes. It has a slightly spicy and peppery taste.

Osaka Purple

This variety features dark purple leaves with a mild, mustard flavor. It is known for its heat tolerance and disease resistance.

Choosing the right variety depends on your personal preference for flavour and appearance. Experimenting with different varieties can add diversity to your garden and culinary creations.

By understanding the climate and soil requirements for growing mustard greens and selecting the right variety, you can set yourself up for success in cultivating these delightful leafy greens in your Australian garden. Whether you're looking to enjoy them fresh in salads or cooked in stir-fries, mustard greens are a versatile and nutritious addition to any home garden.

Planting Mustard Greens

To start growing mustard greens in Australia, you have two options: starting from seeds or transplanting seedlings. Both methods have their advantages, so let's explore each one.

Starting from Seeds

Starting mustard greens from seeds is a cost-effective and rewarding way to grow these leafy greens. Here's how you can do it:

  1. Choose high-quality seeds: Select organic mustard green seeds from a reputable supplier or save seeds from a previous crop.
  2. Prepare the soil: Mustard greens thrive in well-drained soil rich in organic matter. Prepare the soil by removing any debris, weeds, or rocks. Add compost or well-rotted manure to improve soil fertility.
  3. Sow the seeds: Sow the seeds directly into the prepared soil. Plant the seeds around 0.5 to 1 inch deep and space them approximately 4 to 6 inches apart. Leave about 12 to 18 inches between rows to allow enough space for the plants to grow.
  4. Water the seeds: After sowing the seeds, water the soil gently but thoroughly. Keep the soil consistently moist until the seeds germinate.
  5. Provide adequate sunlight: Mustard greens require at least 4 to 6 hours of direct sunlight per day. Choose a sunny spot in your garden for optimal growth.
  6. Thin out the seedlings: Once the seedlings emerge and develop their first set of true leaves, thin them out to maintain proper spacing. Remove the weaker seedlings, leaving the healthiest ones to grow.

Transplanting Seedlings

If you prefer a head start, you can also transplant mustard green seedlings into your garden. Here's how you can do it:

  1. Purchase or grow seedlings: Obtain healthy mustard green seedlings either by purchasing them from a nursery or by growing them from seeds indoors.
  2. Prepare the planting area: Clear the planting area of weeds and debris. Ensure that the soil is well-drained and has been enriched with compost or organic matter.
  3. Dig holes: Dig holes in the soil that are slightly larger than the root ball of the seedlings. Space the holes approximately 4 to 6 inches apart, leaving 12 to 18 inches between rows.
  4. Place the seedlings: Gently remove the seedlings from their containers and place them in the prepared holes. Ensure that the top of the root ball is level with the soil surface.
  5. Backfill and firm the soil: Backfill the holes with soil, gently firming it around the base of the seedlings. Avoid compacting the soil too much, as it may hinder root growth.
  6. Water the transplanted seedlings: After transplanting, water the seedlings thoroughly to help them settle into their new environment. Maintain consistent moisture in the soil as the seedlings establish themselves.

By following these planting methods, you'll be on your way to growing delicious and nutritious mustard greens in your own garden. Remember to provide proper care, including regular watering, fertilising, and pest management, to ensure healthy growth.

Caring for Mustard Greens

To ensure the successful growth of your mustard greens, it's important to provide proper care and attention. This includes watering and irrigation, fertilising and nutrient requirements, as well as pest and disease management.

Watering and Irrigation

Mustard greens require consistent moisture to thrive, especially during the germination and growth stages. It's important to keep the soil evenly moist, but not waterlogged, to prevent the roots from rotting. Aim to provide about 1 inch of water per week, either through rainfall or irrigation.

When watering, it's best to do so in the morning to allow the leaves to dry before evening. This helps prevent the growth of fungal diseases. Avoid overhead watering as it can increase the risk of diseases. Instead, use a soaker hose or water at the base of the plants to ensure the roots receive sufficient moisture.

Fertilising and Nutrient Requirements

To promote healthy growth and maximize yield, mustard greens benefit from regular fertilisation. Before planting, incorporate well-rotted compost or aged manure into the soil to improve its fertility. This provides a good foundation of organic matter and nutrients for the plants.

During the growing season, you can further support your mustard greens with a balanced organic fertilizer. Apply the fertiliser according to the manufacturer's instructions, ensuring you distribute it evenly around the plants. This helps provide the necessary nutrients for robust growth and flavorful greens.

Pest and Disease Management

Like any plant, mustard greens can be susceptible to pests and diseases. Common pests that may attack your mustard greens include aphids, flea beetles, and caterpillars. Regularly inspect the plants for signs of infestation, such as chewed leaves or sticky residue. If you notice any pests, consider using organic pest control methods, such as handpicking or applying neem oil.

In terms of diseases, mustard greens can be affected by fungal infections like powdery mildew and downy mildew. To prevent the spread of diseases, it's important to maintain good air circulation by spacing the plants adequately. Additionally, avoid overhead watering and water at the base of the plants to minimise leaf moisture. If necessary, apply organic fungicides as directed.

By providing adequate water, proper nutrition, and managing pests and diseases, you can ensure the health and vitality of your mustard greens. This will result in an abundant harvest of delicious and nutritious greens. For more information on growing other vegetables and herbs in Australia, check out our A-Z grow guides.

Harvesting and Using Mustard Greens

Once your mustard greens have reached maturity, it's time to enjoy the fruits of your labour. In this section, we will explore harvesting techniques, culinary uses of mustard greens, and storing and preserving these flavorful greens.

Harvesting Techniques

Mustard greens can be harvested at various stages of growth, depending on your preference. For baby greens, harvest the outer leaves when they reach about 3-4 inches in length. This allows the inner leaves to continue growing. Alternatively, you can wait for the plants to mature and harvest the entire plant when it reaches about 8-12 inches in height.

When harvesting mustard greens, use a sharp pair of scissors or garden shears to cut the leaves just above the soil level. Be sure to leave a few leaves on the plant so it can continue to grow and produce more greens. Harvesting regularly promotes new growth and ensures a continuous supply of fresh mustard greens.

Storing and Preserving Mustard Greens

To extend the shelf life of your harvested mustard greens, it's important to store them properly. Here are some tips for storing and preserving mustard greens:

  • Refrigeration: Place unwashed mustard greens in a plastic bag or container and store them in the refrigerator. They can stay fresh for up to a week.
  • Freezing: If you have an abundance of mustard greens, consider blanching them before freezing. To blanch, briefly submerge the greens in boiling water for a few seconds, then transfer them to an ice bath to stop the cooking process. Once cooled, drain and package the greens in airtight freezer bags or containers. Frozen mustard greens can be stored for up to six months.
  • Preserving: Mustard greens can also be preserved by pickling or fermenting. These methods add tanginess and depth of flavor to the greens, allowing you to enjoy them long after the growing season.

By using proper harvesting techniques and exploring various culinary uses, you can make the most of your homegrown mustard greens. Whether you enjoy them fresh in salads or cooked in a warm, comforting dish, these nutritious greens are a delightful addition to any meal.
