Origin
Turbina oblongata (E.Mey. ex Choisy) A.Meeuse, also known as Derris elliptica (Wall. ex Benth.) Baker f. or Flageoletia elliptica (Wall. ex Benth.) S.Moore, is originally from tropical areas of Asia such as India, Indonesia, and Thailand.
Common Names
The plant is commonly known as the potato vine, derris vine, and tuba in the Philippines.
Uses
The plant has been traditionally used for its medicinal properties. Its roots and bark contain rotenone, a substance known to have insecticidal properties and is commonly used as a pesticide. The root and bark are also used as a remedy for various ailments such as rheumatism, skin diseases, and snake bites.
Turbina oblongata is also used in traditional medicine to improve brain function, relieve pain, and reduce inflammation. Additionally, it is used to treat parasitic infections, such as worms, amoebas, and tapeworms.
General Appearance
Turbina oblongata is a woody vine that can grow up to 5 meters in length. It has elliptical leaves that are 8-15 cm long and dark green in color. The plant produces small, greenish-white flowers that are arranged in clusters and bloom from August to October. The fruit is a flat pod, approximately 5 cm long, containing one to two seeds.
The plant's roots and bark have a yellowish-brown color and a strong, aromatic smell.
Light Requirements
Turbina oblongata requires full sunlight to grow properly. A minimum of six hours of direct sunlight is essential for healthy growth. However, the plant can tolerate partial shade for a short period during the day, but extended periods of low light can inhibit growth and flowering.
Temperature Requirements
The ideal temperature for the growth of Turbina oblongata is between 18°C to 30°C. The plant can tolerate a wide range of temperatures, but extreme hot or cold conditions can be detrimental to growth. Frost can be deadly to Turbina oblongata.
Soil Requirements
Turbina oblongata thrives best in a well-draining soil with a pH range of 6.0 to 7.5. The soil should be rich in organic matter and able to retain adequate moisture. Sandy soil with some clay content is desirable. Avoid waterlogged or compacted soil as it can lead to root rot and stunted growth.
Cultivation of Turbina Oblongata
Turbina oblongata is a beautiful plant that can be grown indoors or outdoors. It is a tropical vine that belongs to the Convolvulaceae family. The plant grows well in warm to hot weather and requires good sunlight to flourish.
You can propagate Turbina oblongata from seeds or stem cuttings. Once the plant starts growing, you can use a trellis or support for its vines. The plant's growth rate is fast, and it requires regular maintenance to keep it under control.
Watering Needs of Turbina Oblongata
Since Turbina Oblongata is a tropical species, it loves humid conditions, but it cannot tolerate standing water as it is prone to root rot. Therefore, it is best to water Turbina Oblongata when the top layer of soil is dry to the touch. Overwatering can be detrimental to the plant's growth, so it is essential to be cautious and ensure good drainage.
Fertilization of Turbina oblongata
The plant responds well to regular fertilization. A well-balanced fertilizer that includes micronutrients and trace minerals can promote its development and keep its foliage healthy. It is advisable to fertilize the plant once every 2-4 weeks to keep it thriving.
Pruning Turbina oblongata
Pruning is necessary to keep the plant looking neat and tidy, as well as to prevent it from getting too unruly. It is recommended to trim the plant's vines after the first flush of flowers to ensure they retain their bushy growth habit. Additionally, pruning Turbina oblongata is essential to prevent vines from getting tangled or choking the plant.
As Turbina oblongata is a vigorous grower, it may be necessary to prune it every few months. Pruning should only be performed during the plant's dormant period, which is typically in the winter season.
Propagation of Turbina oblongata
Turbina oblongata (E.Mey. ex Choisy) A.Meeuse, commonly known as the upright moonflower or snake vine, is a perennial plant that belongs to the Convolvulaceae family. Propagation of this plant can be done through several methods:
Seeds
One of the easiest ways to propagate Turbina oblongata is by using its seeds. The plant produces elongated capsules that contain four seeds each. The seeds can be collected and sown directly in the ground or in seed trays. Seeds that are sown directly in the ground should be placed in a sunny location with well-draining soil. Seeds that are sown in seed trays should be covered lightly with soil and kept moist until germination.
Cuttings
Another method of propagating Turbina oblongata is through stem cuttings. Cuttings should be taken from the plant in the spring or summer. The cut should be made at a 45-degree angle, just below a node. The cutting should be approximately 6 inches long and have several leaves attached. The lower leaves should be removed, and the cutting should be placed in a pot of moist potting soil. The cutting should be placed in a warm, bright location and kept moist until roots develop.
Division
Turbina oblongata can also be propagated through division. This method involves separating the plant into smaller sections and replanting them. This is typically done in the spring or fall. To divide the plant, gently dig up the entire plant and separate the roots into sections. Each section should have several stems and a healthy root system. Replant each section in a location with well-draining soil and full sun.
Overall, Turbina oblongata is a relatively easy plant to propagate, and growers can choose the method that works best for them.
Disease and Pest Management of Turbina Oblongata
Turbina oblongata, commonly known as the devil's claw, is a shrub with medicinal properties. The plant is hardy and can resist many pests and diseases effectively. However, like any other plant, it is susceptible to some pests and diseases.
Common Diseases That Affect Turbina Oblongata
Some common diseases that affect Turbina oblongata include:
- Root Rot: This is a fungal disease that affects the roots of the plant, causing them to decay. This can cause stunted growth and even death of the plant. To manage this disease, avoid overwatering the plant and ensure proper drainage.
- Powdery Mildew: This is a fungal disease that affects the leaves of the plant, causing a powdery white substance to form on the leaves. The affected leaves may also turn yellow and die. To manage this disease, prune off the affected leaves and apply a fungicide.
- Leaf Spot: This is a fungal disease that affects the leaves of the plant, causing circular spots to appear on them, which eventually turn into holes. To manage this disease, prune off the affected leaves and apply a fungicide.
Common Pests That Affect Turbina Oblongata
Some common pests that affect Turbina oblongata include:
- Aphids: These are small insects that feed on the sap of the plant, causing stunted growth and death of the plant. To manage this pest, spray the plant with an insecticide.
- Spider Mites: These are tiny insects that spin webs on the leaves of the plant and suck sap, causing the leaves to turn yellow and fall off. To manage this pest, prune off the affected leaves and spray the plant with an insecticide.
- Caterpillars: These are the larvae of moths or butterflies that feed on the leaves of the plant, causing them to have holes. To manage this pest, handpick the caterpillars or spray the plant with an insecticide.
Prevention is the best way to manage diseases and pests. Ensure that the plant is grown in well-drained soil, and avoid overwatering. Also, ensure that the plant is pruned regularly to remove dead and diseased parts. Lastly, ensure that the plant is grown in an environment that is not conducive for pests to thrive.
