Overview
Pittosporum feddeanum Pax is a species of flowering plant in the Pittosporum family. It is native to China and was first described by eminent German botanist Ferdinand Albin Pax in 1902. It is known for its ornamental value and medicinal properties.
Common names
The Pittosporum feddeanum Pax is commonly known by various names, including Chinese Pittosporum, Fei Hua Che, and Bai Jian Lan.
Appearance
The Chinese Pittosporum is a small to medium-sized evergreen tree, which can grow up to 10 metres tall. The leaves are glossy, leathery, and dark green, ranging in shape from oval to lanceolate, measuring about 8-12 cm in length. The tree produces clusters of small, sweet-scented flowers that are white to cream in colour and bloom in late spring and early summer. The fruits are woody capsules that contain seeds that are covered in a sticky substance.
Uses
The Chinese Pittosporum is highly valued for its ornamental value and is widely used in landscaping and gardening. It is an excellent tree for hedges, borders, and screens as it can be pruned and shaped to form various shapes and sizes. The tree is drought tolerant, making it a suitable choice for gardens in dry areas.
It is also used for medicinal purposes in traditional Chinese medicine. Its leaves and branches are used to treat intestinal and respiratory ailments, including cough, asthma, and bronchitis. It is also known for its anti-inflammatory and anti-tumor properties.
Light Requirements
The Pittosporum feddeanum Pax plant requires a moderate amount of sunlight for optimal growth. It can thrive in partially shaded areas, but insufficient light can slow down growth and result in a spindly, weak plant. Therefore, it is best to place it in an area that receives at least four to six hours of indirect sunlight per day.
Temperature Requirements
The Pittosporum feddeanum Pax plant prefers a warm and humid environment like its native habitat. It can tolerate a wide range of temperatures but is sensitive to frost and cold drafts. Ideally, the plant should be kept in a temperature range of 60°F to 80°F (15°C to 27°C). To maintain the required humidity, misting the plant regularly can help.
Soil Requirements
The Pittosporum feddeanum Pax plant prefers well-draining soil that is rich in organic matter and slightly acidic. A good potting mix can be made by mixing equal parts of peat moss, perlite, and vermiculite. The pH range for the soil should be between 5.5 to 6.5. The plant is susceptible to root rot, so the soil must never be waterlogged. Watering the plant when the topsoil is dry to the touch is recommended.
Cultivation methods
Pittosporum feddeanum Pax is native to China and can be grown in USDA hardiness zones 8 to 11. It prefers well-draining soil that is slightly acidic and rich in nutrients. Ensure that the site has enough light, as the plant requires partial to full sunlight to thrive.
The plant is relatively easy to grow and can be propagated by seeds, stem cuttings, or layering. For optimal growth, transplant young plants into the ground or larger containers with enough space for the roots to spread. The plant can be grown as a shrub or tree, depending on the desired size.
Watering needs
Pittosporum feddeanum Pax requires moderate watering, with slightly moist soil being ideal. Overwatering or underwatering can lead to the plant's decline or death. During hot and dry seasons, ensure that the plant gets enough water to prevent wilting or drying of the leaves. It is crucial to avoid watering the foliage, as this may increase the risk of fungal infections.
Fertilization
Fertilizing Pittosporum feddeanum Pax makes for better growth and health. It is advisable to apply slow-release fertilizer in the early spring or fall, as this is when the plant is actively growing. Water the plant before and after applying the fertilizer to prevent the burning of the roots. Follow the manufacturer's instructions for the recommended rate of application as over-fertilizing can lead to salt build-up in the soil.
Pruning
Pruning Pittosporum feddeanum Pax promotes healthy growth and shape. It is essential to prune the plant before the growing season to avoid reducing the number of flowers or fruits. Cut off dead or diseased branches, snip off any sprouts, and shape the plant to the desired size. For a more natural appearance, avoid pruning more than one-third of the plant's foliage at a time.
Propagation of Pittosporum feddeanum Pax
Pittosporum feddeanum Pax, also known as the Taiwanese Cheesewood, is a tropical shrub or small tree that is native to Taiwan. It has become a popular ornamental plant due to its attractive foliage, stunning flowers, and easy care requirements. Propagation of Pittosporum feddeanum Pax can be done by various methods, including seed germination, cuttings, and layering.
Seed Germination
Pittosporum feddeanum Pax is propagated by seeds during late spring to early summer. The seeds are first soaked in warm water for 24 hours to soften the hard seed coat. After soaking, the seeds are sown in well-draining potting soil and covered with a thin layer of soil. The seeds should be kept moist and warm, preferably in a greenhouse or indoor environment, until they start to germinate, which usually takes 6 to 8 weeks. Once the seedlings have grown to around 2 inches tall, they can be transplanted into larger pots or directly into the ground.
Cuttings
Pittosporum feddeanum Pax can also be propagated by stem cuttings during late spring to summer. Cuttings should be taken from the current year's growth, around 4 to 6 inches long, and include a few leaves. The cuttings should be dipped in rooting hormone and planted into a well-draining potting mix. The container should then be covered with a plastic bag to maintain high humidity and placed in a warm area with bright, indirect light. After 4 to 6 weeks, the cuttings should have developed roots, and the plastic bag can be removed.
Layering
Layering is another propagation method that can be used to propagate Pittosporum feddeanum Pax. In layering, a low branch is bent to the ground and covered with soil, leaving the tip exposed. The branch is held down in place with a stake or weight. Once roots have formed, which usually takes several months, the branch can be cut away from the parent plant, and the new plant can be transplanted into a new location.
Disease and Pest Management for Pittosporum feddeanum Pax
Pittosporum feddeanum Pax is generally a low-maintenance plant, however, like any plant, it may be susceptible to certain pests and diseases that can affect its health and growth. Proper disease and pest management is crucial to ensure the longevity and well-being of the plant.
Common Diseases
The most common disease that affects Pittosporum feddeanum Pax is root rot. This condition is caused by overwatering and poorly-draining soil, leading to the roots’ deterioration. To avoid root rot, it is important to ensure that the plant is grown in well-drained soil, and never overwatered or left in standing water.
Pittosporum feddeanum Pax can also be affected by leaf spot, which is caused by fungal spores. This condition presents as dark spots on the leaves. To manage leaf spot, it is important to keep the plant’s foliage dry, avoid overhead watering, and prune away any affected leaves or stems immediately.
Common Pests
The most common pests that may affect Pittosporum feddeanum Pax are aphids, mites, and scales. These pests feed on the plant’s sap, leading to wilted leaves and stunted growth. To manage these pests, the use of insecticidal soap can be effective. It is important to note that strong pesticides may also harm beneficial insects.
Another pest that can affect Pittosporum feddeanum Pax is thrips. These pests feed on the plant’s flowers and leaves, causing damage to the foliage. To manage thrips, the use of insecticidal soap or neem oil can be effective.
Preventive Measures
The best way to keep Pittosporum feddeanum Pax healthy and pest-free is to take preventive measures. These can include regularly inspecting the plant for signs of pests or disease, pruning away any affected leaves or stems, avoiding overhead watering, and ensuring proper drainage of the soil. Additionally, maintaining good soil health by adding compost and other amendments can ensure that the Pittosporum feddeanum Pax is receiving the necessary nutrients to keep it healthy and strong.
By taking preventative measures and properly managing any pests or diseases that may occur, your Pittosporum feddeanum Pax plant will flourish and provide you with years of beauty and enjoyment.
