General Appearance
The Cape Restharrow is a thin, wiry shrub that grows up to a height of 1-2 meters. Its stems are green with short hairs, and they can be either hairy or smooth. The leaves of the plant are grey-green and are composed of three oval-shaped leaflets, which are around 1-2 cm in length and width.
The flowers of Ononis capensis L. bloom during spring and summer, and they are pink or purple in color. These flowers grow in clusters on the tops of the stems. The fruits that develop after flowering are small, dry pods that contain one or two seeds.
Common Uses
Ononis capensis L. has various medicinal uses. Tea made from the roots and leaves of the plant is used to treat diarrhea, colic, and stomach pain. The medicinal properties of the plant are also attributed to its high levels of tannins, flavonoids, and alkaloids.
In addition, the plant is also used as a natural insect repellent. Crushed leaves or stems of the Ononis capensis L. plant can be placed in cupboards or drawers to repel moths and other insects.
The Cape Restharrow is also commonly used in landscaping and gardening. Due to its hardiness and tolerance to drought, it is often used as an ornamental plant in rock gardens or as a ground cover.
Light Requirement
Ononis capensis L. typically prefers full sunlight exposure, although it can tolerate partial shady conditions. It is a robust plant that grows best in direct sunlight. Access to direct sunlight is crucial since the plant uses sunlight to carry out photosynthesis.
Temperature Requirement
The plant has a wide range of climatic tolerance and can thrive in many different regions. The ideal temperature range for Ononis capensis growth is between 20°C to 32°C (68°F to 90°F). However, it can survive in temperatures as low as 5°C (41°F) and up to 40°C (104°F).
Soil Requirement
The plant can grow in any soil type. However, it prefers soils with good drainage, geographic soil, and a pH range between 5.5-7.5. The soil must be fertile and rich in essential nutrients, including nitrogen, phosphorous, and potassium. The plant also thrives in soil that is slightly acidic to neutral. In addition, it is known to withstand drought conditions and can grow in sandy and clay soils.
Cultivation of Ononis capensis L.
Ononis capensis L. is a shrubby, evergreen plant that is indigenous to the Western Cape Province of South Africa. The plant grows best in Mediterranean climates with mild winters and warm, dry summers.
The ideal location for planting Ononis capensis L. is in a sunny spot with well-draining soil. The plant is drought-tolerant, so it doesn't require frequent watering.
You can plant Ononis capensis L. in the garden or in a container. If you're planting in a container, make sure it's large enough to accommodate the plant's roots.
Watering needs
While Ononis capensis L. is drought-tolerant, it still requires regular watering during its growing season. Water the plant deeply once a week, allowing the soil to dry out slightly between waterings. Avoid overwatering as the plant is prone to root rot. During winter, you can reduce the watering frequency.
Fertilization
Ononis capensis L. doesn't require regular fertilization, but you can fertilize the plant with a balanced fertilizer once a month during its growing season. Avoid fertilizing during winter when the plant is dormant. Over-fertilization can cause the plant to produce more leaves than flowers.
Pruning
Ononis capensis L. requires minimal pruning, but you can shape the plant by pruning back the tips of the branches once a year in spring. Pruning will encourage growth and improve the plant's overall appearance. You can also remove any dead or diseased wood throughout the year as you notice it.
Propagation of Ononis capensis L.
Ononis capensis L., commonly known as the coppery pea, is a perennial plant that belongs to the Fabaceae or legume family. If you are planning to propagate Ononis capensis L., there are several methods you can use.
Propagation by Seeds
The most common method of propagating Ononis capensis L. is through seeds. You can collect mature seed pods and spread their seeds in the desired planting location. Once you have scattered the seeds, cover them with a thin layer of soil and water them lightly. The seeds will germinate in approximately two to three weeks, and you will start to see seedlings emerge from the soil. When the seedlings have grown to a sufficient size, you can transplant them to their permanent location.
Propagation by Cuttings
Another method of propagating Ononis capensis L. is through stem cuttings. Choose a healthy and mature stem, about 10-15cm long, and cut it just below a leaf node using a sharp and sterilized pruning shear. Strip off the leaves from the lower half of the stem cutting and dip the cut end in rooting hormone powder. Plant the cutting in a pot filled with a well-draining soil mixture, making sure to water it regularly. After two to three weeks, the cutting should have formed roots, and you can transplant it to its permanent location.
Propagation by Division
You can also propagate Ononis capensis L. through division. The best time to divide the plant is in autumn when the plant is dormant. Dig up the plant with a shovel, taking care not to damage the roots. Use a sharp knife or hand pruners to divide the root ball into small sections, making sure each section has some roots and shoots. Plant the divided sections in their permanent location and water them regularly.
With these simple methods, you can easily propagate Ononis capensis L. and enjoy the beauty of this lovely perennial plant in your garden.
Disease and Pest Management of Ononis capensis L.
Ononis capensis L., commonly known as the Cape restharrow, is a shrubby plant that belongs to the Fabaceae family. Being a vulnerable plant, it can be affected by several diseases and pests that can cause significant damage if not managed appropriately. Here are some of the common diseases and pests that might affect Ononis capensis L. and how to manage them.
Diseases
Ononis capensis L. can be affected by several diseases that may affect its growth and productivity. Some of the most common diseases of Ononis capensis L. include:
Root rot
Root rot is a fungal disease that affects the roots of Ononis capensis L. plants leading to wilting, yellowing, and finally death. The disease is caused by a fungus called Phytophthora cinnamomi. To manage root rot, it is essential to use clean planting material and avoid waterlogging. Ensure the soil is well-draining, and avoid over-irrigation.
Powdery Mildew
Powdery mildew is a fungal disease that affects the leaves of Ononis capensis L. plants leading to a powdery white appearance on the surfaces of leaves and stems. The disease is caused by a fungus that thrives in warm and humid conditions. To manage powdery mildew, it is essential to maintain good air circulation around the plants and avoid watering the leaves. Additionally, you can use fungicides to manage the disease.
Rust
Rust is a fungal disease that affects the leaves of Ononis capensis L. plants leading to reddish-brown pustules on the leaves and stems. The disease is caused by a fungus that thrives in cool and moist conditions. To manage rust, it is essential to remove and destroy infected parts of the plant. Additionally, you can use fungicides to manage the disease.
Pests
Ononis capensis L. is also vulnerable to several pests that can cause severe damage. Some of the most common pests that might affect Ononis capensis L. include:
Aphids
Aphids are small sap-sucking insects that cause wilting and stunted growth in Ononis capensis L. plants. To manage aphids, you can use insecticides or introduce natural predators like ladybugs.
Thrips
Thrips are small insects that feed on the flowers and leaves of Ononis capensis L., causing deformities and discoloration. To manage thrips, you can use insecticidal soap or introduce natural predators like parasitic wasps.
Spider mites
Spider mites are tiny pests that suck sap from Ononis capensis L. plants, causing discoloration and stunted growth. To manage spider mites, you can use insecticidal soap or introduce natural predators like predatory mites.
Overall, managing diseases and pests in Ononis capensis L. requires a combination of preventive measures and proper management practices. It is essential to monitor the plants regularly and take appropriate action promptly when symptoms of diseases or pests are detected.
