Overview
Correa backhouseana is a small shrub native in Australia. It belongs to the family Rutaceae and is commonly known as Backhouse Correa or Coastal Correa.
Appearance
The plant typically grows up to 1.5 meters in height and width. It has narrow, dark green leaves that are about 2.5-6 cm long and 2-6 mm wide. Its bell-shaped flowers are a unique feature, with pale yellow-green petals, red tips, and a tinge of pink on the underside. The plant produces flowers from late summer through fall.
Uses
Correa backhouseana is a popular garden plant, commonly used as a hedging or screening plant due to its dense foliage. The plant thrives in a variety of conditions, including full sun to partial shade and can tolerate frost and coastal conditions. The flowers of Correa backhouseana are also attractive to nectar-feeding birds, making it an ideal plant for bird attracting gardens.
Indigenous Australians used Correa backhouseana for medicinal purposes, including the treatment of respiratory problems, skin conditions and infections.
Cultivation
Correa backhouseana is relatively easy to grow and maintain with low water requirements and occasional pruning. It prefers well-drained soil and can tolerate dry conditions. Fertilizing the plant with low-phosphorous fertilizer helps enhance growth and flowering.

Light requirements
Correa backhouseana needs partial shade to full sun exposure for optimal growth. It requires at least 4-6 hours of direct sunlight per day to thrive.
Temperature requirements
It prefers mild-temperate climates and can tolerate light frost. The optimal temperature range for Correa backhouseana is between 50-77°F (10-25°C). However, it can tolerate temperatures as low as 28°F (-2°C) and as high as 104°F (40°C).
Soil requirements
Correa backhouseana grows best in well-draining soils with a slightly acidic to neutral pH range of 6.0-7.5. The soil texture can range from sandy to loamy, but it is crucial to avoid waterlogged or heavy clay soils. Adding organic matter like compost or well-rotted manure can improve soil fertility and structure.
Fertilizer requirements
Correa backhouseana does not require heavy feeding as it is adapted to nutrient-poor soils. Applying a balanced fertilizer at half-strength once in early spring and once in mid-summer can help enhance growth and flowering. Avoid using high-nitrogen fertilizers as they can promote excessive foliar growth at the expense of flowers.
Water requirements
Correa backhouseana has moderate water needs and prefers consistently moist but not waterlogged soils. It is essential to water deeply and infrequently rather than shallowly and frequently. During the hot and dry summer months, it may require more frequent watering to prevent wilting and stress.
Cultivation of Correa backhouseana
Correa backhouseana, also known as the native fuchsia, is a shrub that requires well-draining soils. It grows well in areas with good air circulation and in full sun or partial shade. In regions with hot climates, it is advisable to plant it in a location with afternoon shade, as extreme heat can affect its growth. Correas are sensitive to frost, so it is essential to plant them in areas that offer some level of protection in the winter.
Watering Needs
Correa backhouseana requires moderate watering, especially in the summer months. Avoid over-watering the plant as it is susceptible to root rot. Water the plant thoroughly when the soil is dry to the touch, and ensure that the soil drains well to prevent waterlogging. In winter, when the plant goes dormant, reduce watering to prevent the soil from becoming too soggy.
Fertilization
Correa backhouseana does not require excessive fertilizer applications, as it is adapted to low nutrient soils. Fertilize the plant twice a year, preferably in spring and late summer, with a balanced fertilizer such as 10-10-10. Apply the fertilizer according to the instructions on the label, and ensure that it does not come into contact with the leaves or stems of the plant.
Pruning
Pruning is a crucial aspect of Correa backhouseana's care. It helps to maintain the plant's shape and promote healthy growth. Prune the plant in early spring before new growth begins, removing any dead or diseased stems and cutting back any overgrown branches to promote new growth. Use clean, sharp pruning shears to avoid damaging the plant's stems. After pruning, mulch around the plant to help conserve moisture in the soil.
Propagation of Correa backhouseana
Correa backhouseana can be propagated through various methods including:
Seed propagation:
Seeds from the ripe fruit can be collected and sown in the spring in a well-drained and fertile soil mix. The seedlings should be watered regularly but not excessively and kept in a partly shaded environment until they develop a strong growth. The young plants can be transplanted to their permanent location when they reach a height of 10 cm.
Cuttings propagation:
Correa backhouseana can be propagated by taking semi-hardwood cuttings in the summer and autumn. The cuttings should be about 10 cm long and should include a portion of the current year's growth. Remove the bottom leaves and dip the cutting stem in a rooting hormone. Plant the cutting in a well-drained and moist soil mix and keep it in a partly shaded area until it develops roots. After the roots have formed, the young plants can be transplanted to their permanent location.
Grafting:
Correa backhouseana can be grafted onto the rootstocks of other species of Correa to create hybrids. This method is mostly used by plant propagators in the cultivation of rare plant hybrids for the horticultural trade.
Propagation of Correa backhouseana can lead to the development of new and vigorous plants with better disease resistance and improved ornamental characteristics, making it an important component of horticultural practices and conservation efforts.
Disease and Pest Management for Correa backhouseana
Correa backhouseana, commonly known as the Victorian Correa, is a hardy plant that usually doesn't suffer from significant disease or pest problems. However, it is essential to keep an eye out for pests and diseases that can harm the plant.
Common Diseases
One of the most common diseases affecting Correa backhouseana is root rot caused by Phytophthora fungus. To avoid root rot, make sure that the soil is well-drained, and do not overwater the plant. If you notice your plant's leaves yellowing and wilting, it might be a sign of root rot.
Another disease that affects Correa backhouseana is Leaf Spot disease caused by the fungus Mycosphaerella. Leaf spot disease leads to the development of brown patches on leaves. To avoid leaf spot disease, make sure to remove any dropped leaf litter from around the plant and dispose of it securely.
Common Pests
The most common pests that can damage Correa backhouseana include spider mites and scale insects. Spider mites are tiny pests that live on the undersides of the leaves and suck the sap from the plant. To get rid of spider mites, use an insecticidal soap and spray it on the affected area. Scale insects are small, wingless insects that attach themselves to the plant's bark and suck the sap from it. To get rid of scale insects, use horticultural oil and spray it on the plant's affected areas.
Pest Prevention
The best prevention for pests and diseases is to keep your Correa backhouseana plant healthy. Make sure to plant it in well-draining soil, prune it regularly, and ensure that it receives enough sunlight. Regularly inspect your plant for signs of diseases and pests and take immediate action to prevent them from spreading.
By following these simple tips, you can ensure that your Correa backhouseana plant remains healthy, thriving, and beautiful.
