Origin
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. is an orchid species that is endemic to the African continent. It was first discovered in Tanzania in the year 1988 and has since been found in various other East African countries such as Kenya and Uganda.
Common Names
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. is commonly known as the Three-fingered Tridactyle or Lisowski's Tridactyle.
Uses
There is limited information on the various uses of Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. However, it is known to possess medicinal properties that may be of benefit for traditional medicine. Its roots are believed to possess antihelminthic properties, while its tubers have astringent properties that have been used to treat wounds and diarrhea in some African communities.
General Appearance
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. is a small-sized orchid that grows up to 10 cm in height. It has a slender, cylindrical stem with fleshy leaves that are oblong to elliptic in shape. The plant bears short inflorescences that produce small, greenish-yellow flowers with three finger-like petals. The lip of the flower is yellow, and its edges are fringed.
Light Requirements
Tridactyle scottellii subsp. lisowskii usually grows in partial to full shade. Direct exposure to the sun can cause the leaves to burn or wilt. It thrives in filtered or dappled sunlight, such as under the canopy of a tree. In an indoor setting, bright indirect light or a mixture of shade and filtered sun would be suitable for this plant.
Temperature Requirements
The ideal temperature range for Tridactyle scottellii subsp. lisowskii is between 18°C to 24°C. It is relatively adaptable to different temperature ranges although it may grow slower or faster in different conditions. The plant is fairly tolerant of colder temperatures but should not be exposed to frost. Young plants should be protected from temperature fluctuations and drafts.
Soil Requirements
Tridactyle scottellii subsp. lisowskii grows well in well-draining soil that is moist but not soaked. It prefers soil with a slightly acidic pH of 5.5 to 6.5. The soil should be rich in organic matter and nutrients, such as peat moss or manure. In its natural habitat, the plant is found growing on rocks or shallow soil. It is important to avoid overwatering this plant.
Cultivation
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. is an epiphytic orchid species, which means it can be grown both mounted on a substrate or potted in a well-draining mix. One popular substrate for this plant is cork bark, to which it can easily attach itself with its aerial roots.
When potting, use a mix of orchid bark, perlite, and charcoal to ensure proper drainage. Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. prefers a humid environment, with a temperature ranging from 18-25°C (64-77°F).
Watering Needs
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. should be watered regularly, but allow the potting mix to dry out slightly between waterings. Never allow the roots to sit in standing water, as this can cause root rot. This plant enjoys high humidity levels so you can mist it daily or place it on a humidity tray.
Fertilization
This plant does not require heavy fertilization, but it should be fed with a balanced fertilizer once per month during the growing season (spring and summer). Dilute the fertilizer to half strength and apply it when watering.
Pruning
Pruning is not necessary for this plant, but it is a good idea to cut back any yellow or withered leaves to help the plant conserve energy.
Propagation of Tridactyle scottellii subsp. lisowskii
Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach., also known as Lisowski's Tridactyle, is a terrestrial orchid species that is endemic to Madagascar. It has unique three-pronged leaves and produces small white flowers. If you want to propagate Tridactyle scottellii subsp. lisowskii, there are two methods that you can use: seed propagation and vegetative propagation.
Seed propagation
You can propagate Tridactyle scottellii subsp. lisowskii from seed. Collect the seed pods when they are ripe and dry. Sow the seeds into pots or trays filled with a well-draining soil mixture. Cover the seeds with a thin layer of soil, and keep the soil moist. The seedlings will germinate in a few weeks to a few months. It's important to note that Tridactyle scottellii subsp. lisowskii has a low success rate in seed propagation, so it's recommended that you propagate using both methods.
Vegetative propagation
Vegetative propagation is another option for propagating Tridactyle scottellii subsp. lisowskii. This method involves taking cuttings from the plant and rooting them. Choose healthy plants that are free of disease or pests. Using a clean, sharp knife, cut a section of stem with at least one node. Dip the end of the cutting in rooting hormone, and plant it in a container filled with a well-draining soil mixture. Keep the soil moist and in a bright, warm location. The cutting should develop roots within a few weeks to a few months.
Disease and Pest Management for Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach.
Being a terrestrial orchid, Tridactyle scottellii (Rendle) Schltr. subsp. lisowskii Szlach. is susceptible to various diseases and pests. Here are some of the common pathogens and pests that might affect the plant and ways to manage them:
Diseases
Fungal Diseases: Tridactyle scottellii is vulnerable to various fungal attacks, including leaf spotting, stem rot, and root rot. Proper irrigation and ventilation, as well as maintaining balanced nutrition, can reduce the likelihood of infection. Using copper-based fungicides and removing damaged parts can help control the spread of the disease.
Bacterial Diseases: Bacterial infections are characterized by yellowing, wilting, and stunted growth. They can be managed by improving sanitation, such as removing infected tissues and avoiding overhead watering. Using copper-based bactericides can also help reduce the symptoms.
Pests
Spider Mites: These tiny pests cause chlorotic spots, webbing, and leaf drop. They can be controlled by regular misting, insecticidal soap, or neem oil.
Scale Insects: These are small, immobile pests that attach themselves to the stems and leaves of the plant, causing yellowing and leaf drop. They can be managed by using a soft-bristled brush to remove them or by applying horticultural oil.
Mealybugs: These small, soft-bodied insects suck on the plant sap and produce a waxy, cottony substance that can cause wilting and stunted growth. They can be managed by wiping the plant with rubbing alcohol or neem oil.
Overall, it is important to maintain good cultural practices, keep the growing environment clean, and pay close attention to changes in the plant's appearance to prevent disease and pest infestations. If the infestation is severe, seeking the help of a professional plant service might be necessary.
