Common Names
Wedelia triternata Klatt is known by various common names such as three-lobed Wedelia, creeping oxeye, yellow dots, and Wedelia.
Light Requirements
Wedelia triternata Klatt is a sun-loving plant. It requires full sunlight exposure to grow and thrive. Therefore, it is recommended to plant it in areas that receive at least six hours of direct sunlight daily.
Temperature Requirements
Wedelia triternata Klatt is a tropical plant and prefers warm temperatures to grow correctly. It grows best in temperatures ranging from 70 - 80°F or 21 - 27°C. This plant cannot tolerate frost and should be protected from cold weather. If planted in cold regions, it should be grown in a greenhouse or indoors in a sunny location to protect it from extreme temperature fluctuations.
Soil Requirements
Wedelia triternata Klatt thrives in well-draining soils that are rich in organic matter. It grows best in soils that are slightly acidic to neutral, with a pH of 6.0 - 7.0. The soil should be kept moist, but not waterlogged, to prevent root rot. This plant can tolerate drought conditions, although it is recommended to water it regularly during extended periods of dry weather.
Cultivation Methods
Wedelia triternata Klatt, also known as Orange Zexmenia, is a shrubby perennial plant that thrives in warm and sunny conditions. It can grow up to 1-2 feet tall and spreads up to 2-3 feet wide. The plant prefers well-drained soil but can adapt to different soil types, including sandy or rocky soils.
To cultivate Wedelia triternata Klatt, start by selecting a site that receives full sunlight or partial shade. Plant the Orange Zexmenia seedlings about 18-24 inches apart to allow enough space for them to spread. Water the newly planted seedlings thoroughly and regularly until the roots have established in the soil.
Watering Needs
Proper watering is essential for the growth and survival of Wedelia triternata Klatt. The Orange Zexmenia plant tolerates drought conditions, but it still needs regular watering to thrive and produce healthy flowers. Water the plant deeply, but infrequently, to encourage deep root growth.
During the summer months, when the temperatures are high, it is best to water the plant once per week. In cooler months, reduce watering frequency to once every ten days. Always ensure that the soil is well-drained, and there are no waterlogged areas around the roots.
Fertilization
Wedelia triternata Klatt is not a heavy feeder and does not require frequent fertilization. However, a light application of a balanced, slow-release fertilizer in the early spring can boost growth and promote flowering.
Alternatively, you can incorporate organic matter, such as compost or well-rotted manure, into the soil in the fall to provide the plant with vital nutrients and improve soil structure.
Pruning
Wedelia triternata Klatt is a fast-growing plant that can become leggy and unkempt without timely pruning. Prune the plant in late winter or early spring before new growth begins. Cut back the stems to a third of their original length, removing any damaged or diseased wood.
Deadhead the faded blooms regularly to encourage the production of a new set of flowers. Regular pruning will also prevent the plant from becoming invasive and keep it in good shape.
Propagation of Wedelia Triternata Klatt
Wedelia triternata Klatt is a low-maintenance plant that spreads quickly and is easy to propagate. Propagation can be done by seeds, cuttings, or division of the root ball.
Propagation by Seeds
Propagation through seeds is the easiest method for Wedelia triternata Klatt, but it may not always be successful. The plant produces small, dry seeds that should be collected in late summer. The seeds should be sown in a seedling tray filled with good quality potting soil. Cover the seeds with a thin layer of soil, and keep the tray in a warm, bright location. Water the seeds regularly and keep the soil moist. The seeds will germinate in 1 to 2 weeks.
Propagation by Cuttings
Propagation through cuttings is the most common method for Wedelia triternata Klatt. Take cuttings from the tip of the stem, about 6 to 8 inches long, with several nodes. Remove the leaves from the bottom half of the cutting. Dip the cut end of the cutting in rooting hormone powder and plant it in sandy soil. Keep the soil moist and place the cutting in a shaded area. After a few weeks, the cutting should develop roots and can be transplanted to their final location.
Propagation by Division
Propagation through division of the root ball is another method for Wedelia triternata Klatt. This method is best done in spring when new growth is starting. Dig up the plant and carefully divide the root ball into several sections, making sure each division has some stems and roots. Plant each division in a well-prepared site and keep the soil moist until new growth appears.
Disease and Pest Management for Wedelia Triternata Klatt
Wedelia triternata Klatt, also known as Orange Zephyrlily, is a perennial plant that belongs to the Asteraceae family. The plant is unpalatable to livestock due to the presence of bitter compounds, but it provides good ground cover and is easy to cultivate in various soil types and environments. However, like any other plant, Orange Zephyrlily is susceptible to pests and diseases that can negatively affect its growth and productivity. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
One of the most common diseases that can affect Orange Zephyrlily is powdery mildew, which is caused by the fungus Erysiphe cichoracearum. Powdery mildew can cause white or grayish patches on the plant's leaves, stems, and flowers, leading to stunted growth and reduced flower production. To manage powdery mildew, you can use fungicides containing sulfur or potassium bicarbonate or apply neem oil on the affected areas. You can also remove and destroy heavily infected plants to prevent the spread of the disease.
Another disease that can affect the plant is rust, which is caused by the fungus Puccinia wedeliae. Rust can cause yellow or orange pustules on the plant's leaves and stems, leading to defoliation and reduced plant vigor. To manage rust, you can use fungicides containing pyraclostrobin, azoxystrobin, or myclobutanil or prune infected leaves and destroy them. Make sure to clean pruning tools after each use to prevent the spread of the disease to healthy plants.
Pests
Orange Zephyrlily is also susceptible to pest infestations that can damage the plant's leaves, stems, and flowers. One common pest that can affect the plant is the Spider mite, which is a tiny arachnid that feeds on the plant's sap, causing yellowing, wilting, and eventual death of the leaves. To manage Spider mites, you can spray the plant with insecticidal soap or neem oil or release predatory mites to feed on them.
The Whitefly is another pest that can affect the plant, especially during hot and dry weather. Whiteflies feed on the plant's sap, causing yellowing and stunted growth of the leaves and transmitting viral diseases. To manage Whiteflies, you can apply insecticides containing imidacloprid or use yellow sticky traps to catch them.
In conclusion, by following proper disease and pest management practices, you can maintain a healthy Orange Zephyrlily plant and maximize its production and aesthetic value. Make sure to monitor the plant regularly for any signs of diseases or pests and take prompt action to manage them before they cause irreversible damage.
