It is native to tropical Africa, mostly found in the Democratic Republic of Congo, Uganda, and Tanzania. The plant grows in a vine-like manner and can reach lengths of up to 10 meters. Zehneria capillacea is highly valued for its medicinal and nutritional benefits, and it is occasionally used as an ornamental plant in gardens.
Common Names
Zehneria capillacea has several common names depending on the region where it is grown. In East Africa, it is known as "Mkirira" or "Kikirikiri," while in West Africa, it is referred to as "Igiri" or "Egiri." In the Democratic Republic of Congo, it is called "Mupupula."
Uses
Zehneria capillacea is a plant of significant importance in traditional African medicine. The leaves, fruits, and roots of the plant are used to cure various ailments such as stomach ache, fever, and malaria. The plant also has antimicrobial and anti-inflammatory properties. Zehneria capillacea is perhaps best known for its nutritional benefits. The young leaves and fruits of the plant are consumed as a vegetable, and they are a good source of vitamin C, phosphorus, and iron. The fruit tastes sweet and is sometimes eaten raw.
General Appearance
Zehneria capillacea is a perennial climber with long, slender stems that curl around support structures, such as trees. The stems, leaves, and fruits of the plant are covered with small, hooked prickles that allow them to latch onto other plants for support. The leaves are simple, broad, and have a heart-shaped base. The flowers of the plant are greenish-white or pale-yellow, and they are produced in clusters. The fruit is a small, oval-shaped berry, initially green and turning orange when ripe.
Overall, Zehneria capillacea is an important plant in traditional African medicine and cuisine, and it remains highly sought after in many parts of Africa despite its relatively obscure status.Light
The plant Zehneria capillacea (Schumach.) C.Jeffrey typically grows well under bright and indirect sunlight. It can tolerate some shade but may not thrive well under low light conditions.
Temperature
Zehneria capillacea (Schumach.) C.Jeffrey is a tropical plant that thrives under warm temperatures. The ideal temperature range for its growth is between 20 - 30°C. It cannot tolerate frost or temperatures below 10°C.
Soil Requirements
The plant Zehneria capillacea (Schumach.) C.Jeffrey prefers well-draining and fertile soil. The soil should be loose, light, and rich in nutrients. A pH range of 6.0 - 6.5 is ideal for its growth. The plant can tolerate some level of soil acidity and salinity but not excessive amounts.
Cultivation methods for Zehneria capillacea
Zehneria capillacea can be cultivated from seeds or stem cuttings, although seeds are preferred as they are easier to germinate. The seeds should be planted in a fertile, well-draining soil mix in pots or seed trays. The pots or trays should be placed in a warm, bright location, and the soil should be kept moist but not waterlogged. Germination can take up to three weeks.
Once the seedlings have developed their second set of true leaves, they can be transplanted into larger individual pots.
Watering needs for Zehneria capillacea
Zehneria capillacea requires consistent moisture but does not tolerate waterlogging. The plant should be watered when the soil is dry to the touch, typically every 1-2 weeks. During hot, dry weather, more frequent watering may be necessary.
The plant also benefits from increased humidity. It can be misted regularly or placed on a tray of pebbles filled with water to increase humidity levels.
Fertilization of Zehneria capillacea
Zehneria capillacea benefits from regular fertilization during the growing season. A balanced fertilizer, applied every 2-3 weeks, will provide the necessary nutrients for healthy growth. It is important not to over-fertilize, as this can lead to chemical burn and other issues.
Pruning Zehneria capillacea
Zehneria capillacea can be pruned to control its growth and shape. The plant can become quite large, so regular pruning will help keep it manageable. Pruning should be done in spring or summer, and any dead or diseased branches should be removed. Pruning can also be done to encourage bushier growth or to shape the plant into a specific form. It is important to use clean, sterilized tools to avoid the spread of disease.
Propagation of Zehneria capillacea (Schumach.) C.Jeffrey
Zehneria capillacea is a perennial climber plant that grows in tropical Africa. Propagation of the plant can be carried out through several methods, including:
Seed Propagation
Zehneria capillacea can be propagated through seeds which can be obtained from mature fruits. The seeds should be extracted from the fruits and dried for some days. The dried seeds can be stored in a cool and dry place to maintain their viability. When ready for planting, the seeds can be sown into planting pots or directly into the ground. The seeds should be sown at a depth of 1-2 cm, and cover with a thin layer of soil. Water the soil and keep it moist until the seedlings emerge.
Cuttings Propagation
Another propagation method for Zehneria capillacea is through stem cuttings. The cuttings can be obtained from a mature plant by cutting a piece of stem about 8-10 cm long. Remove the lower leaves from the cutting, leaving a few at the top. Dip the cutting in rooting hormone powder and plant it in a pot filled with a mixture of sand and peat. Keep the soil moist and place the pot in a warm and brightly lit spot until the cutting develops roots. Once the cutting has developed roots, it can be transplanted into a larger pot or directly into the ground.
Air Layering Propagation
Air layering is another propagation method that can be used for Zehneria capillacea. This method involves making a cut on the stem of a mature plant and covering the cut with moist soil or sphagnum moss. The covered area should be wrapped with plastic to keep the soil or moss moist and to prevent it from drying out. Roots will form from the cut area within a few weeks. Once the roots are well developed, the new plant can be cut from the mother plant and transplanted into a new pot or directly into the soil.
Division Propagation
Zehneria capillacea can also be propagated through division. Carefully dig out the root ball of the mature plant and separate it into smaller sections. Each section should contain a healthy portion of the root system and some stems. Transplant the divided sections into new pots or directly into the soil. Ensure that the soil is kept moist until new growth emerges.
Propagation through any of these methods can help to increase the number of Zehneria capillacea plants for gardening or land reclamation projects.
Disease Management for Zehneria capillacea (Schumach.) C.Jeffrey
Zehneria capillacea is known to be susceptible to foliar diseases such as powdery mildew, leaf spot, and downy mildew.
To manage powdery mildew, it is important to practice good sanitation by removing all infected plant parts and avoiding overhead watering. Applications of fungicides such as neem oil or sulfur can also help to control powdery mildew.
Leaf spot can be managed by removing and destroying infected leaves. Fungicides such as copper-based products can also be applied to manage this disease.
Downy mildew can be managed by controlling moisture levels around the plants, avoiding overhead watering, and improving air circulation around the plant. Fungicides containing copper or other chemicals can also be used to manage downy mildew.
Pest Management for Zehneria capillacea (Schumach.) C.Jeffrey
Zehneria capillacea may be attacked by pests such as spider mites, aphids, and whiteflies.
To manage spider mites, it is important to maintain adequate moisture levels in the soil and avoid over-fertilization. Natural predators such as ladybugs and lacewings can also be introduced to control spider mites.
Aphids can be managed by blasting them off the plant with a strong stream of water or by introducing natural predators such as ladybugs or parasitic wasps. Pesticides can also be used to control aphids.
Whiteflies can be managed by introducing natural enemies such as ladybugs or parasitic wasps or by using yellow sticky traps to capture adults. Pesticides can also be used to control whiteflies.
