Tephrosia lactea Schinz is a perennial plant that is native to South Africa and Zimbabwe. It is a member of the Fabaceae family, also known as the legume or pea family. The plant is called Tephrosia which means "ash-colored" in Greek, referring to the plant's grayish-green appearance.
General Appearance
Tephrosia lactea Schinz is a small shrub that typically grows up to 1.5 meters tall. The leaves of this plant are compound, with three leaflets that are ovate to elliptic in shape. The leaf margins are entire, and there are usually two small stipules at the base. The stems and leaves of this plant are covered with fine hairs, giving them a slightly hairy texture.
The flowers of Tephrosia lactea Schinz are white to pale pink in color and are arranged in clusters at the end of the stems. They have a papilionaceous structure, typical of the pea family, with five petals. The fruit of this plant is a cylindrical pod that is about 2 to 3 centimeters long and contains several seeds.
Common Names
Tephrosia lactea Schinz is known by several common names, including:
- Mooiplaas-hapjassie
- Mooiplaas-pea
- Rebellepisgat
- White tephrosia
Uses
Tephrosia lactea Schinz has several uses in traditional medicine. The roots of this plant are used to treat gastrointestinal disorders, such as diarrhea and dysentery. The leaves can be boiled and used to make a poultice that can be applied to wounds to promote healing. The plant also has insecticidal properties and can be used to control pests in crops.
Beyond its medicinal uses, this plant also has ecological benefits. As a legume, Tephrosia lactea Schinz has the ability to fix nitrogen in the soil, improving soil fertility and crop yields. It is also used as a cover crop to control soil erosion and maintain soil moisture.
Overall, Tephrosia lactea Schinz is a versatile plant with many benefits and uses. Its hardy nature and ability to thrive in a variety of conditions make it an important plant for both traditional medicine and agriculture.Light Requirements
Tephrosia lactea Schinz grows well in full sunlight or partial shade. It requires at least 6 hours of sunlight exposure each day for optimum growth and development. Insufficient sunlight reduces the plant's ability to produce flowers and fruits.
Temperature Requirements
This plant prefers warm temperatures. It grows well in temperatures between 20 - 30°C. It cannot tolerate frost or extreme cold temperatures. If temperatures drop below 10°C, it may cease to grow and may even die in severe cases.
Soil Requirements
The plant thrives in well-draining, fertile soil that retains moisture. It prefers soils with a pH range of 6.0 to 7.5. The soil should be rich in organic matter and have good aeration to allow for proper root development. Tephrosia lactea Schinz also requires occasional fertilization to maintain its growth and health.
Cultivation Methods
Tephrosia lactea Schinz, commonly known as Milky Tephrosia or White Hoary Pea, is an attractive flowering plant that requires minimal effort to cultivate. It is a hardy plant that can grow in a wide range of soils and environmental conditions.
The best time to plant Tephrosia lactea Schinz is during the rainy season when the soil is well-drained and moist. Dig a hole that is slightly larger than the size of the root ball and allow some space between each plant (at least 50 – 75cm) to ensure proper air circulation.
Watering Needs
Watering the plant is essential for its growth, especially in its first year. Tephrosia lactea Schinz requires regular watering, especially when planted in sandy or well-draining soil. Water the plant once every 3 – 4 days (more frequently during hot spells) and do not allow the soil to dry out completely.
Avoid watering the plant excessively, as it can lead to root rot. Always ensure that the soil has good drainage to avoid waterlogging the roots.
Fertilization
Tephrosia lactea Schinz is a leguminous plant that has a unique ability to fix nitrogen from the air, meaning it needs minimal fertilization.
However, during the growing season, especially when the plant is flowering, a light application of balanced fertilizer or organic compost can be added. This will help to enhance the plant's growth and increase flower production.
Pruning
Tephrosia lactea Schinz requires occasional pruning to maintain its shape and encourage healthy growth. Prune the plant regularly to remove dead or diseased parts that can attract pests or harbor diseases.
Pruning can also be done to control the plant's size and shape. You can trim the plant to maintain its desired size, but avoid over-pruning, as it may reduce the plant's ability to produce flowers.
Propagation of Tephrosia lactea Schinz
Tephrosia lactea Schinz is a flowering plant that belongs to the family Fabaceae. It is commonly propagated by seed and cuttings. Both methods have their advantages and disadvantages, and the choice of propagation method will depend on the grower's goals and resources.
Propagation by Seed
Propagation by seed is the most common method for Tephrosia lactea Schinz. It is recommended to harvest the seeds from mature plants during the dry season. The harvested seeds should be carefully cleaned and dried before storage. Seeds can be stored for up to three years.
Before planting, the seeds should be soaked in water for 24 hours to soften the seed coat. This will aid in germination. The soil should be well-drained, and a mix of compost and sand is recommended. Sow the seeds about 2 cm deep and water them regularly to keep the soil moist. Germination usually takes between 2 and 4 weeks.
It is important to note that seed-grown plants may not be true to type, meaning they may not have the same characteristics as the parent plant.
Propagation by Cuttings
Propagation by cuttings is another method for Tephrosia lactea Schinz. This method involves taking a stem cutting from the parent plant. Cuttings should be taken during the early part of the growing season, and the stem should be at least 10 cm long and have at least three nodes.
The cuttings should be treated with rooting hormone powder to increase the chances of successful rooting. The cuttings can be planted directly into well-drained soil, preferably a mix of compost and sand. The soil should be kept moist, and the cutting should be protected from direct sunlight until it is established.
The advantage of propagation by cuttings is that the new plant will be genetically identical to the parent plant.
Disease and Pest Management for Tephrosia Lactea Schinz
Tephrosia lactea Schinz is a tough and hardy perennial plant that is typically resistant to most pests and diseases. However, several diseases and pests can still hamper the plant's growth and health. Effective management of the pests and diseases requires constant monitoring and immediate intervention measures.
Common Diseases
One of the most common diseases that affect Tephrosia lactea Schinz is root rot. Excessive watering or poorly drained soils can lead to root rot. The plant's roots become weak and develop dark brown discoloration, leading to stunted growth, yellowing of leaves, and eventual death. To manage root rot, stop watering the plant for a few days and improve the drainage system.
Another common disease that affects Tephrosia lactea Schinz is leaf spot. Leaf spot is characterized by brown or yellow spots on the plant's leaves. It is caused by several fungi that thrive in moist conditions. To prevent leaf spot, avoid watering the plant's leaves and improve air circulation around the plant. If leaf spot has already affected the plant, remove the affected leaves and burn them to prevent further spread of the fungus.
Common Pests
One of the most common pests that affect Tephrosia lactea Schinz is aphids. Aphids are small insects that suck sap from the plant's leaves, causing stunted growth, yellowing of leaves, and eventual death. To manage aphids, spray the plant with a jet of water to knock off the insects. Alternatively, you can use insecticidal soap to kill aphids effectively.
Another common pest that affects Tephrosia lactea Schinz is spider mites. Spider mites are tiny pests that suck sap from the plant's leaves, causing yellowing, stippling, and complete defoliation. To manage spider mites, spray the plant's leaves with water, increase the humidity level around the plant, and use insecticidal soap
