Goji Berries In Australia: Can They Grow?

do goji berries grow in australia

Goji berries, native to the Himalayas and inner Mongolia, are known for their health benefits and can be consumed fresh, dried, or in juice form. They can also be grown in Australia, where the climate is suitable for their cultivation. Goji berries can be grown from seeds or seedlings, and they thrive in full or partial sunlight and moist, well-drained soil. They are also suitable for container gardening, though they fruit better when grown in the ground. With proper care, Australians can enjoy the benefits of growing their own goji berries.

Goji berries are well-suited to the Australian climate

Goji berries, also known as Chinese Wolfberries, Boxthorn, Duke of Argyll's teaplant, or Lycium barbarum, are indeed well-suited to the Australian climate. Native to the Himalayas and inner Mongolia, goji berries have been used for thousands of years as food and for their health benefits. They are now cultivated in Australia, particularly in northern NSW, and can be purchased from Bunnings stores.

Goji berries are a perennial plant, which means they grow year-round in most climates. They are well-suited to the hot, dry summers of Australia, thriving in full sun or partial shade. When planting, it is recommended to choose a position with full or partial sun and moist, well-drained soil. Goji berry plants will grow in nutrient-poor soils and do not require additional fertiliser during the growing season. They can be grown directly from seeds, which can be sown directly into the garden or started in trays and then transplanted. The ideal soil temperature for germination is 20-25°C, and germination typically occurs within 14-28 days.

In terms of care, goji berry plants respond well to regular pruning and can be kept neat and tidy. They can be grown in containers, but they will fruit better when cultivated in the ground. It may take up to five years to reach maximum production, but with proper care, goji berry plants can provide an abundant harvest of nutritious berries.

When harvesting, it is important to wait until the berries are fully coloured. The berries can be consumed fresh, dried, juiced, or frozen. Goji berries have a flavour similar to sour cherries or cranberries, making them a versatile ingredient in both sweet and savoury dishes.

Overall, goji berries are a resilient and well-adapted crop for Australian gardeners, offering a tasty and healthy treat.

Germination and soil requirements

Goji berries can be grown from seeds or seedlings. Seeds can be sown directly into the garden, or seedlings can be raised in trays or other containers and transplanted to the garden once they are established and large enough to handle (around 5-10cm tall). The germination time for goji berries is approximately 14-28 days when sown at a soil temperature of 20-25°C. However, it is important to note that soil temperature usually differs from air temperature and germination may occur outside this window or not at all if the ideal temperature is not met.

Goji berries can be grown in various soil types, but they prefer a sunny position with moist, well-drained soil. They will grow in poorer soils, but it is recommended to improve the soil before planting by adding compost, manure, or fertiliser to increase moisture retention and nutrient content. The soil's pH level should be between 6.8 and 8.1, and you can add sand or compost to improve the texture if necessary. Goji berries also grow well in pots when planted with a premium potting mix, but a container size of at least 20 litres is recommended.

Container gardening

Goji berries can be grown in containers, which is a good option if you lack garden space. The goji berry plant is a perennial that grows year-round in most climates, including in Australia. It can be grown in USDA plant hardiness zones 3 to 10, and containers allow you to bring the plant inside when temperatures drop in autumn.

When selecting a container, choose one that is large enough for the mature plant. A minimum volume of 40 litres is recommended for goji berries, and while width is not as critical, a deep container is best to allow for more growth. A pot with a diameter of at least 18 inches (46 cm) is sufficient.

Use a good-quality potting mix and refresh it at least once a year by working in some organic material. Place the container where the plant will receive at least eight hours of sunlight per day. If this is not possible, you may need to use a full-spectrum or grow light. Stake the plant if it begins to sprawl. Goji berries generally don't require much pruning, but you can prune lightly to encourage branching and maintain a neat appearance.

Goji berry seeds can be sown directly into the container, or seedlings can be raised in trays and transplanted once they are established. Seeds should be sown 8mm deep and 200cm apart. Keep the soil moist but never wet or dry. Germination should occur within 14-28 days at a soil temperature of 20-25°C. Protect young seedlings from pests, pets and weather until they are established.

During the growing season, container-grown goji berry plants may need additional fertiliser to encourage healthy growth. Water the plants when the soil is dry about 5cm below the surface. Water deeply in the early morning or late afternoon and avoid watering the leaves to prevent fungal diseases.

Pests and diseases

Goji berries are susceptible to a variety of pests and diseases. They are prone to blossom end rot, a physiological disorder caused by a lack of calcium uptake, often due to inconsistent watering. This can be remedied by regularly adding calcium to the soil and maintaining a consistent watering schedule.

Common pests affecting goji berries include aphids, trips, and gall mites. Gall mites are a significant concern, as they target the leaves, chewing on the foliage and forming galls within the leaf structure to lay their eggs.

Fungal diseases are also a primary concern for goji berries. Powdery mildew, a common issue, appears as white patches on the leaves and can reduce fruit production. Horticulture oil sprays can help manage this disease. Anthracnose is a more severe fungal infection that occurs during hot and humid weather, leading to fruit rot. Affected branches should be removed promptly, and special attention should be given to cleaning up garden debris where the disease can overwinter.

Additionally, goji berries are susceptible to insect infestations and fungal infections, often requiring large volumes of pesticides for control. However, the pervasive use of chemical pesticides has led to widespread contamination of raw goji berries. Unlicensed and improperly applied pesticides can have adverse effects on consumers, causing short-term ailments and potentially contributing to long-term disorders.

Goji berry seedlings also require protection from pests and weather conditions until they are fully established.

Harvesting and aftercare

Goji berries are usually ready for harvesting in late spring to summer. They turn red very quickly but will be bitter until fully ripe. It is best to leave them on the plant for several weeks after turning red to allow their flavour to develop. Taste the berries regularly to determine when they are ready for harvest.

Goji berries are easy to harvest. The berries grow in clusters, making harvesting simple and efficient, even in smaller spaces. The plants are self-fertile, meaning you will get fruit from a single plant. However, the harvest will be heavier if you have two varieties acting as pollinator buddies.

The goji plant matures and develops lateral branches over time, leading to more abundant harvests in the years to come. Regular pruning encourages healthy fruit production and can also induce a second fruiting period. Pruning in late winter will encourage strong new growth in spring.

To promote healthy growth, the soil should be amended with compost or rotted manure to boost fertility, while mulching helps retain moisture and suppress weeds. Goji berry plants also benefit from fertilisation when they break dormancy in spring and after fruiting in the autumn. Ensure the plants are well-watered during late spring and summer as the fruit develops. A regular liquid feed during this period will be beneficial.

Finally, managing pests and diseases is crucial for a successful harvest. Spider mites and powdery mildew are common concerns, especially in hot weather and poor air circulation. Goji berry plants should have adequate spacing, and pruning can improve airflow around the foliage. Insecticidal soap can effectively control pests without harming the plants.
