Soil requirements
For optimal growth, the soil must be well-draining and rich in organic matter. The recommended soil composition is a mixture of peat moss, perlite, and vermiculite. It is important to ensure that the soil is moist but not waterlogged as this can lead to root rot. The pH level of the soil should be between 5.5 to 6.5 as Habenaria humbertii Szlach. & Olszewski prefers slightly acidic soil. Fertilizers can be used during the active growing phase, but it is important not to over-fertilize as this can cause damage to the roots and leaves.
Cultivation Methods
The Habenaria humbertii Szlach. & Olszewski is a terrestrial orchid species that prefers moist and well-draining soil. When cultivating the plant, make sure to plant it in soil that is rich in organic matter and has a pH level between 5.5 and 6.5.

The seeds can then be sown on a well-draining medium. Cover the seeds with a thin layer of soil and ensure that the medium is kept moist. The seeds will germinate within two to four weeks, and the seedlings can then be transplanted once they are large enough to handle.
Vegetative Propagation:
Vegetative propagation of Habenaria humbertii involves the separation of the offsets or bulbs, which grow along the rhizome. The offsets can be divided into smaller pieces and planted in a well-draining medium. Ensure that each piece has sufficient roots and at least one shoot. Water the offsets thoroughly to promote root growth. Once established, the new plants can be transplanted outside.
Propagation through tissue culture is also a possibility for Habenaria humbertii, but this method requires a laboratory setup, and it is not commonly practiced by home gardeners.
Regardless of the method used, ensure that the plants are kept in a shaded area with high humidity until they are well established.
