Soil: Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. grows well in well-drained soil that is rich in organic matter. It can grow in various soil types, including sandy and loamy soils. However, it cannot grow in waterlogged or poorly drained soils. It prefers neutral to slightly acidic soil with a pH level between 6 and 7.
Water: This species prefers moderate to high humidity levels. It requires regular watering during the growing season, especially during the dry season. However, it cannot tolerate waterlogging, and the soil should be allowed to dry out slightly between watering.
Cultivation of Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr.
Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. is a terrestrial orchid that requires well-draining soil with a high organic matter content. It is best grown in containers, as the plant is fairly small. When selecting a container, choose one that is slightly larger than the plant's rhizome to allow room for growth.
The plant prefers a partially shaded to fully shaded location, and grows well at temperatures between 20-30°C. In areas with high humidity, the plant can be grown outdoors, but in drier climates, it should be grown indoors.
Watering Needs
Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. should be watered regularly but not excessively. Overwatering can lead to root rot, while underwatering can cause the plant to dry out. Water the plant when the top inch of soil feels dry to the touch.
When watering, make sure to avoid watering the leaves, as this can cause fungal diseases. Instead, water the soil around the plant.
Fertilization
Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. should be fertilized every two weeks during the growing season (spring and summer). Use a balanced fertilizer with an equal ratio of nitrogen, phosphorus, and potassium.
When applying fertilizer, dilute it to half strength and water the plant before and after application to prevent fertilizer burn.
Pruning
Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. does not require pruning other than the removal of dead leaves or flowers.
To remove dead leaves or flowers, cut them off at the base of the stem using a clean pair of scissors.
Propagation of Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr.
Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. can be propagated through various methods, including seed propagation, division propagation, and tissue culture propagation.
Seed Propagation
The seeds of Satyrium bracteatum (L.f.) Thunb. var. saxicolum (Bolus) Schltr. are small and dust-like. Sow the seeds thinly on the surface of a seedling mix, and cover them with a thin layer of sand. Water gently and cover the container with a plastic bag to retain moisture. Place the container in a warm, well-lit area. Germination can take anywhere from one to four months.
Division Propagation
Division propagation can be carried out when the plant has formed clumps. Carefully separate the clumps into smaller sections, ensuring that each section has sufficient roots. Replant the sections in a suitable potting mix, water them well, and provide bright, indirect light.
Tissue Culture Propagation
Tissue culture propagation involves taking small pieces of tissue from the plant and culturing them in a sterile nutrient medium. This method requires specialized laboratory equipment and expertise, making it the most challenging and expensive form of propagation.
