Some people also use the leaves to make traditional herbal teas for medicinal purposes. The plant is also cultivated as an ornamental plant for its attractive foliage and as a ground cover.
General Appearance of Husnotiella revoluta Card.
Husnotiella revoluta Card. has succulent, cylindrical stems that are green or reddish in color. The stems are about 5-10 cm tall and spread out in a circular rosette form. The leaves are obovate, fleshy, and alternate in arrangement, with a reddish or purplish color at the base. The flowers are small and greenish and are arranged in clusters at the end of the stem. The plant thrives in areas with a mild, humid climate and prefers well-drained soils.
Light Requirements
Husnotiella revoluta Card. thrives well in direct sunlight to partially shaded conditions. It requires sufficient light for photosynthesis, which helps in the production of energy for the plant's growth and development.
Temperature Requirements
The ideal temperature for the growth of Husnotiella revoluta Card. is between 20°C to 25°C. It can tolerate temperatures as low as 10°C and as high as 35°C. However, exposure to extreme temperatures for extended periods can adversely affect the plant's growth and survival.
Soil Requirements
Husnotiella revoluta Card. prefers well-drained soils that are rich in organic matter. The plant requires a pH range of 5.5 to 7.2 for optimal growth. In addition, the soil should be able to retain adequate moisture to prevent waterlogging, which can cause the roots to rot. The use of fertilizer is also recommended to provide the necessary nutrients for the plant's growth and development.
Cultivation Methods
Husnotiella revoluta is a tropical epiphytic plant that grows on trees. Cultivation of this plant involves mimicking its natural habitat as much as possible. This means providing it with a well-draining substrate and a host plant to grow on.
For cultivation, it is advisable to use a bark-based substrate, mixed with sphagnum moss or coconut coir. The mixture should be placed in a basket or mounted on a piece of wood or cork bark, as this plant does not grow well in pots.
Watering Needs
This plant requires moderate to high humidity levels, which means that it should be watered regularly. It is important to note that this plant does not tolerate standing water in its substrate, so make sure the mixture is well-draining.
Watering should be done when the substrate starts to dry out, but not to the point where it becomes bone dry. During hot and dry weather, it may be necessary to water the plant more frequently.
Fertilization
Fertilization is not a necessity for this plant, but if it is desired, it should be done sparingly. It is advisable to use a balanced fertilizer, diluted to half strength, once a month during the growing season.
It is important to note that over-fertilization can lead to the buildup of salts in the substrate, which can be toxic to the plant. It is better to err on the side of caution and fertilize less rather than more.
Pruning
Husnotiella revoluta does not require pruning, as it has a naturally compact growth habit. However, if some of the leaves or stems are damaged or dead, they can be removed with a clean, sharp pair of scissors or pruners.
It is important to sterilize the pruning tool before and after use, to prevent the spread of disease. Sterilization can be done by wiping the blade with rubbing alcohol or dipping it in boiling water for a few seconds.
Propagation of Husnotiella revoluta Card.
Husnotiella revoluta Card. is a plant species that belongs to the family Rubiaceae. It is commonly known as "Biswalo" and is endemic to Madagascar. This plant can be propagated through various methods.
Seed propagation
The most common method of propagating Husnotiella revoluta Card. is by seed. The seeds of this plant can be collected when they are mature and sown immediately in a well-drained soil mix. They should be covered lightly with soil and watered regularly. Germination may take several weeks to months, and the seedlings must be protected from direct sunlight and excessive heat.
Vegetative propagation
Husnotiella revoluta Card. can also be propagated vegetatively, using stem cuttings or division. Stem cuttings should be taken from healthy, mature plants. The cuttings should preferably be taken from the tip of the stem and should be around 10-15 cm in length. They should be planted in a moist soil mix and kept in a shaded area until the roots have formed.
Division is another method of vegetative propagation, but it should be done only if the plant has developed a clump of roots. The clump should be carefully separated into sections, ensuring that each section has some roots attached. The sections should then be planted in a well-drained soil mix and watered regularly until they have established.
Overall, Husnotiella revoluta Card. is a relatively easy plant to propagate, and it can be grown from both seeds and vegetative propagation methods. With proper care and maintenance, this plant can enhance the beauty of any garden or landscape.
Disease Management
Husnotiella revoluta Card. is susceptible to several diseases such as rust, powdery mildew, and leaf spot. Rust appears as small, yellow-orange pustules on the undersides of leaves, and powdery mildew looks like a white, powdery coating on leaves and stems. Leaf spot causes small, circular lesions on leaves.
To manage rust and powdery mildew, it is important to remove infected parts of the plant and make sure the plant has good air circulation. Fungicides may also be useful for controlling these diseases but should be used according to instructions. To manage leaf spot, it is recommended to remove any infected plant material and avoid overhead watering to reduce leaf wetness.
Pest Management
Aphids, spider mites, and whiteflies are common pests that can affect Husnotiella revoluta Card. Aphids can be seen as tiny, green or black insects that suck sap from the plant. Spider mites cause yellowing of leaves, and whiteflies appear as tiny, white flies that flutter around the plant.
To manage aphids, it is recommended to spray the plant with a solution of water and dish soap or use insecticidal soap. Spider mites can be managed by regularly spraying the plant with water or releasing predatory mites. Whiteflies can be managed by using yellow sticky traps or applying neem oil.
It is important to regularly inspect plants for signs of pests and diseases, to remove any affected plant parts immediately, and to maintain good plant hygiene to prevent the spread of pests and diseases.
