The use of an appropriate potting mix or a combination of peat moss, perlite, and sand should be used to ensure proper drainage. Avoid using heavy soils or soils that compact easily as this can cause root rot.
Cultivation Methods
Eulophia thollonii Szlach. & Olszewski is a terrestrial orchid species that grows well in warm and humid environments. It thrives in well-draining soil that is rich in organic matter, and is typically propagated through seedlings. The plant should be situated in a semi-shaded or shady location that receives ample indirect sunlight.
Watering Needs
Although Eulophia thollonii Szlach. & Olszewski requires consistent moisture, it should not be overwatered and should only be watered when the top inch of soil becomes dry to the touch. Adequate drainage must be provided to prevent waterlogging, which can lead to root rot and other fungal diseases.
Fertilization
Eulophia thollonii Szlach. & Olszewski should be fertilized every other week during the growing season with a balanced fertilizer (10-10-10), and liquid seaweed or fish emulsion may also be used to supplement the plant's nutrient needs.

Propagation of Eulophia thollonii Szlach. & Olszewski
Eulophia thollonii Szlach. & Olszewski is a terrestrial orchid that is native to Madagascar. It is a rare and endangered orchid species that is considered vulnerable due to habitat destruction and over-collection. Propagation of this orchid species is quite challenging and requires specialized techniques and expertise.
Propagation methods
The propagation of Eulophia thollonii can be achieved by two methods, namely:
Seed propagation
Seed propagation is the most commonly used method for propagating Eulophia thollonii orchid. The seeds need to be collected from ripe seed pods from the orchid plant. The seeds are then cleaned and sterilized to remove any microbes and fungi that may cause harm to the developing seedlings. The sterilized seeds are then sown on special media that provides a suitable environment for the seedlings to grow and develop. The media needs to be kept moist, and the seedlings need to be kept in a humid environment until they are big enough to be transplanted into individual pots.
Division propagation
Division propagation is another method used for propagating Eulophia thollonii orchids. This method involves dividing the orchid plant into smaller sections that each have their own growth points or buds. The sections are then potted in individual containers filled with a specialized orchid mix. The newly potted plants need to be placed in a shade house or under a shade cloth to protect them from direct sunlight and drying out until they have established themselves.
Overall, successful propagation of Eulophia thollonii orchid requires aseptic techniques, specialized media, and environmental conditions that support the growth and development of the seedlings or divided sections of the plant.
