Overview
Neorautanenia pseudopachyrhiza is a flowering plant that belongs to the genus Neorautanenia, family Apiaceae. It is also commonly known as "false pachyrhiza".Origin
The plant is native to several African countries, including Zimbabwe, Tanzania, and Zambia. It is typically found in grasslands and open savannas, often growing in rocky areas.Appearance
Neorautanenia pseudopachyrhiza is a perennial herb that can grow up to 60 cm tall. It has a taproot that can reach up to 3 meters deep. The stems are slender and branched, with alternate, finely dissected leaves. The flowers are small and white, arranged in umbels at the end of the stems.Uses
In traditional African medicine, various parts of the plant, including the roots, bark, and leaves, are used to treat a range of ailments, such as stomach troubles, toothache, and respiratory infections. The plant is also used for its aromatic properties, with the roots and leaves being burned as incense. In addition to its medicinal and aromatic uses, Neorautanenia pseudopachyrhiza is also used as a grazing plant for livestock. The taproot is particularly valuable, as it allows the plant to survive in harsh conditions and provides an important food source for animals during periods of drought.Light Requirements
Neorautanenia pseudopachyrhiza prefers bright light conditions for optimal growth. This plant thrives in full sun to partial shade conditions. It is essential to avoid exposing the plant to direct sunlight during the hottest part of the day as it can damage the leaves. Therefore, an ideal location for this plant is where it can receive morning and evening sun and be shaded during the hottest part of the day.
Temperature Requirements
The ideal temperature range for the growth of Neorautanenia pseudopachyrhiza is between 15°C to 27°C. This plant can grow in both warm and cool climates. However, it should be protected from frost as this can cause fatal damage to the plant. Additionally, fluctuations in temperature can be detrimental to the growth of this plant, and it is important to avoid sudden temperature drops or spikes.
Soil Requirements
Neorautanenia pseudopachyrhiza requires well-draining soil with good moisture retention. Ideally, the soil should be loamy, fertile, and have a slightly acidic to neutral pH (6.0 to 7.5). It is also important to ensure that the soil is rich in organic matter for optimal growth. This plant prefers soils with a slightly sandy texture and can tolerate moderate levels of drought once established.
Cultivation of Neorautanenia pseudopachyrhiza
Neorautanenia pseudopachyrhiza is a relatively easy plant to cultivate. It prefers a moderate climate and can withstand drought-like conditions for short periods.
The plant prefers partial shade and can be grown in either pots or garden beds. When planting, ensure that the soil is well-draining, as waterlogged soil can quickly kill the plant.
Watering Needs
Neorautanenia pseudopachyrhiza requires infrequent but deep watering. The plant is drought tolerant and can survive on minimal water, but it will thrive if given adequate watering.
During hot and dry periods, it is best to water the plant deeply once a week. When watering, ensure that the water reaches the roots and saturates the soil completely. Avoid overwatering the plant, as it may cause root rot.
Fertilization
Neorautanenia pseudopachyrhiza requires minimal fertilizer to grow. However, if you want to give your plant an extra boost, use a slow-release fertilizer during the beginning of the growing season.
A well-balanced fertilizer with equal parts nitrogen, phosphorus, and potassium is ideal for this plant. Always follow the instructions on the fertilizer packaging and avoid overfertilizing, as it can damage the plant.
Pruning
Neorautanenia pseudopachyrhiza does not require regular pruning. However, if the plant becomes too dense or unruly, it may benefit from a light pruning.
Pruning the plant during the dormant season will promote new growth and prevent the plant from becoming too leggy or unsightly. Cut back any dead or damaged branches and remove any crossing limbs that may cause damage or block sunlight.
Propagation of Neorautanenia pseudopachyrhiza (Harms) Milne-Redh.
Neorautanenia pseudopachyrhiza is a fascinating plant with unique properties that makes it an excellent choice for propagation through various techniques. This plant can be propagated either by seeds or vegetative means, including stem cuttings, basal offsets, and division.
Propagation by seeds
The propagation by seeds is one of the most common and straightforward methods for propagating Neorautanenia pseudopachyrhiza. The seeds need to be soaked in hot water for several hours, and it is essential to change the water frequently during this process. After soaking, it is best to plant the seeds in a medium that is moist and well-drained. The container should be kept in a warm, well-lit area and regularly watered to keep the soil consistently moist.
Propagation by stem cuttings
Propagation by stem cuttings is another popular method of propagating Neorautanenia pseudopachyrhiza. The stem cuttings should be taken from the plant during the growing season, preferably in spring or early summer. Using a sharp, sterile knife, cut a few inches of stem, making sure that each cutting has at least one node. Place the cutting in a rooting hormone, then plant it in a well-draining soil mix and keep the soil consistently moist until new growth appears.
Propagation by basal offsets
Propagation by basal offsets is a simple way to propagate Neorautanenia pseudopachyrhiza. This method involves removing the young plants or offsets that grow from the base of the main plant. Once the offsets have been removed, plant them in a well-draining soil mix and keep the soil consistently moist until new growth appears.
Propagation by division
Propagation by division is an effective method of propagating Neorautanenia pseudopachyrhiza. The best time to divide the plant is during the growing season, preferably in spring when the plant is actively growing. To divide the plant, gently dig up the roots and separate them into smaller sections using a sharp, sterile knife. Each section should have at least one healthy shoot and a good amount of roots. Replant the divided sections in well-draining soil mix and keep the soil consistently moist until new growth appears.
Disease Management
The Neorautanenia pseudopachyrhiza (Harms) Milne-Redh. plant is highly susceptible to various diseases. The most common diseases that may affect the plant include root rot, leaf spot, and powdery mildew.
Root Rot: The root rot disease is caused by the presence of several types of fungi in the soil. The infected plant may show signs of wilting, yellowing, and the leaves may fall off. To manage the disease, avoid overwatering or underwatering the plant and ensure that the soil is well-draining.
Leaf Spot: This disease is caused by bacteria and fungi, which lead to the development of spots on the leaves. If left uncontrolled, the spots may enlarge and cause the leaves to die. Management of leaf spot disease can be done by regularly removing the infected leaves, ensuring good air circulation around the plant, and avoiding overhead watering.
Powdery Mildew: This disease is caused by a fungus that forms white powdery patches on the leaves and stems. It can be controlled using fungicides, ensuring that the plant is not planted too closely together, and avoiding overhead watering.
Pest Management
The Neorautanenia pseudopachyrhiza (Harms) Milne-Redh. plant is susceptible to pest infestations. Common pests that may damage the plant include spider mites, aphids, and mealybugs.
Spider Mites: Spider mites feed on plant juices, causing the leaves to become yellow and dry. To manage spider mites, it is necessary to rinse the plant thoroughly, increase humidity, and use insecticidal soaps or oils.
Aphids: Aphids are small insects that feed on the sap of plants, causing the leaves to become yellow and distorted. To manage aphids, one can use insecticidal soap or neem oil and also plant companion plants that repel aphids such as marigold or chives.
Mealybugs: These pests are covered with a waxy substance and feed on plant sap. They can cause the plant to become weakened and stunted. To manage mealybugs, it is necessary to dip a cotton swab in alcohol and apply it to the affected areas or use insecticidal soaps or oils.
