Origin
Capparis biloba Hutch. & Dalziel, commonly known as the "African caper," is a flowering plant that originates from tropical regions in Africa, such as Tanzania, Zambia, and Zimbabwe.
Common Names
Besides the African caper, Capparis biloba also goes by other names, including "two-lobed caper," "marabu," and "umThunzi-wam."
Uses
Capparis biloba has various medicinal uses. The roots, bark, and leaves of the plant possess anti-inflammatory and analgesic properties, making them useful in treating rheumatism, ulcers, and various skin conditions. Additionally, the plant's unripe fruit can be pickled and used as a condiment.
General Appearance
Capparis biloba is a shrub or small tree that can grow up to 7 meters in height. The plant has a thorny stem and thin branches that sprout from reddish-brown bark. The leaves are elongated, about 8-20 cm long, and have an oval shape with slightly pointed tips. The flowers of Capparis biloba are white or pale yellow and bloom throughout the year. The fruit of the plant is a greenish-brown, oval-shaped berry that is about 3 cm long and contains numerous seeds.
Light Requirements
Capparis biloba Hutch. & Dalziel requires full sun exposure to grow optimally. The plant requires direct sunlight for at least six hours daily to thrive. Therefore, it is essential to plant it in an area with ample sunlight to ensure the plant gets enough light.
Temperature Requirements
The ideal temperature for Capparis biloba Hutch. & Dalziel is between 60°F and 85 °F. The plant is relatively tolerant to a wide temperature range and can still grow under extreme temperatures. The plant can survive the occasional frost but cannot withstand a prolonged cold spell. In areas where temperatures regularly fall below 60°F, it would be best to grow the plant indoors or in a greenhouse.
Soil Requirements
Capparis biloba Hutch. & Dalziel grows best in well-drained soils that are rich in organic matter. The soil type should be sandy or loamy with a pH range of 7 to 8. The ideal soil moisture content should be around 40 to 50%. If the soil is too compact or retains too much water, it can lead to root rot and other issues that can cause stunted growth or plant death. Before planting, it is advisable to amend the soil with organic matter such as compost, manure, or peat moss to improve the soil structure and fertility.
Cultivation
Capparis biloba is a tropical plant that requires warmth and sunlight. It can grow well in either sandy or loamy soil types. The plant can also tolerate a pH range of 5.0-7.5, but it is advisable to maintain a neutral pH of 6.5-7.0 for optimal growth and yield.
Propagation can be done through seeds, cuttings, or air layering. Seeds should be planted during the rainy season when the soil is moist and warm. Cuttings and air layering should be done during the dormant period to prevent damage to young shoots.
The plant requires enough space for proper growth and development. Spacing of about 3-4 meters between plants is ideal.
Watering Needs
Capparis biloba requires sufficient water, especially during the dry season. Newly planted seedlings should be watered regularly to establish a comprehensive root system. Mature plants require watering every five to seven days throughout the year.
However, overwatering should be avoided as it can lead to root rot. The soil should be checked for moisture content before any watering is done. This can be achieved by sticking one's finger in the soil to determine its moistness.
Fertilization
The plant requires periodic fertilization to ensure healthy growth and yield. Organic fertilizers such as well-rotted manure or compost are highly recommended. The fertilizer should be applied during the rainy season and spread evenly around the plant's base, taking care to avoid the stem. The recommended amount is five to ten kilograms per plant per year.
Additionally, foliar feeding can be done using water-soluble fertilizers such as liquid seaweed or fish emulsion. This type of fertilizer can be administered two to three times a year during the growing season.
Pruning
Pruning is an essential aspect of caring for Capparis biloba. It is recommended that pruning be done after harvesting the fruit, which usually occurs between May and August. Pruning should be selective, removing only dead, diseased, or damaged branches and shoots.
The plant's natural shape should be maintained by pruning the branches to an outward-growing bud. This encourages the plant to grow more leaves and flowers, which ultimately leads to increased yields in the following harvest season.
Propagation of Capparis biloba Hutch. & Dalziel
Capparis biloba Hutch. & Dalziel, commonly known as "Two-lobed Capparis", is an evergreen shrub native to West Africa. It is grown for its edible fruits, medicinal benefits, and ornamental value. Propagation of this plant can be done using various methods, including:
Seed Propagation
The most common method of propagation for Capparis biloba is through seeds. The ripe fruits should be collected and opened to remove the seeds. The seeds should be thoroughly cleaned and sown directly into nursery beds. It is important to note that the seeds have a hard seed coat and may require scarification before sowing to enhance germination. Scarification can be done by mechanical or chemical means. In about three weeks, the seedlings should emerge, and they can be transplanted to their permanent site after six months.
Cuttings Propagation
Propagation of Capparis biloba can also be done by stem cuttings. Semi-hardwood cuttings of about 8-10cm length should be obtained from the current season's growth. The cutting should be treated with a rooting hormone and inserted into a potting mix of sand and peat. The cuttings should be kept in a warm, humid place and watered regularly. Rooting should occur in about 8-12 weeks, and the cuttings can be transplanted into their permanent site.
Air Layering Propagation
Air layering is another method of propagating Capparis biloba. Select a healthy stem about 1cm in diameter and make an upward cut of about 2-3cm. Dust the area with rooting hormone and wrap it with moist sphagnum moss. After a few weeks, roots will appear, and the stem can be cut and transplanted to its permanent site.
Overall, Capparis biloba Hutch. & Dalziel can be propagated through seed, cuttings, or air layering. Growers can choose the method that works best for them based on factors such as available resources, time, and expertise.
Disease and Pest Management of Capparis biloba Hutch. & Dalziel
Capparis biloba Hutch. & Dalziel, commonly known as the two-leaf caper, is an evergreen shrub that has an important economic value. It is grown for its edible flower buds, which are used as a flavoring agent, condiment, and medicine. However, the plant is susceptible to various pests and diseases that can reduce its productivity and quality. Therefore, it is crucial to implement effective management strategies to keep the plant healthy and productive.
Common Pests that Affect Capparis biloba
One of the most damaging pests of Capparis biloba is the fruit fly, Bactrocera oleae. This pest attacks the fruit of the plant, causing significant damage and reducing the yield. Other pests that can affect the plant include aphids, mealybugs, and whiteflies. These insects feed on the sap of the leaves and stems, weakening the plant and making it susceptible to diseases.
Management of Pests
To manage pests on Capparis biloba, it is crucial to monitor the plant regularly and identify the pest problem early. Various cultural, mechanical, and chemical control measures can be employed. Some cultural practices that can reduce pest infestation include pruning of infected tissues and removing the debris around the plant. Mechanical control involves physically removing the pests by handpicking or using traps. Chemical control involves the use of pesticides that are effective against the specific pest. The choice of pesticide should be based on its efficacy, safety, and environmental impact.
Common Diseases that Affect Capparis biloba
Capparis biloba is susceptible to various fungal diseases, including powdery mildew, anthracnose, and rust. Powdery mildew is characterized by the white powdery coating on the leaves, while anthracnose and rust cause leaf spots and discoloration. Other diseases that can affect the plant include bacterial leaf spot and viral diseases, such as cucumber mosaic virus.
Management of Diseases
To manage diseases on Capparis biloba, it is crucial to implement preventive measures that can reduce the incidence and severity of the disease. Cultural practices such as pruning, proper irrigation, and fertilization can help improve the plant's health and increase its resistance to diseases.
