Ensure that the soil stays moist at all times. Transplant the orchid to a new container once every two years after removing the old soil.
Watering Needs for Satyrium buchananii Schltr.
Proper watering is essential for the growth of Satyrium buchananii Schltr. Overwatering or underwatering can harm the plant significantly. Water the plant when the topsoil is dry. Use lukewarm water to discourage any shock to the plant.
Once every two weeks, the plant should be given a thorough watering, ensuring that it reaches the bottom of the pot. Dump out any excess water that remains in the saucer. The plant should not be allowed to sit in standing water.
Fertilization of Satyrium buchananii Schltr.
During the growing season of spring and summer, Satyrium buchananii Schltr. should be fertilized every two weeks. Use a balanced fertilizer with an equal amount of nitrogen, potassium, and phosphorous. Fertilize plants after watering to avoid fertilizer burn.
During their dormant periods in fall and winter, do not fertilize the plant. Resume fertilizing once the plant starts to produce new leaves during the spring season.
Pruning Satyrium buchananii Schltr.
Satyrium buchananii Schltr. does not need extensive pruning. Trim yellowed or browned leaves that appear old and wilted using clean, sharp scissors. Cut above where the leaf meets the stem carefully. Regular pruning of any spent plant parts can be done once the growth cycle is complete. Be careful not to cut any new growth as it may hinder the plant's progress.
Propagation of Satyrium buchananii Schltr.
Satyrium buchananii Schltr., commonly known as the Buchanan's Satyrium, is a terrestrial orchid species that can be propagated through different methods such as seeds, division, and offsets.
Propagation through Seeds
The most common and preferred method of propagating Satyrium buchananii Schltr. is sowing seeds. The seeds require a humid, sterile, well-draining, and nutrient-rich growing medium to germinate successfully. To improve the germination rate, seeds must be sown soon after harvest. These orchid seeds are small and light and need to be mixed with a fine layer of the growing medium or sterilized sand to distribute them uniformly. Daily misting or watering can help to maintain the required growing medium moisture level. They need to be kept warm, preferably between 20-25°C until they germinate, which could take up to 18 months. Once the seedlings reach a mature stage, about two to four years, they can be transferred to pots or directly planted in a garden bed.
Propagation through Division
Another propagation method for Satyrium buchananii Schltr. is through division, particularly for mature orchid plants that have overgrown their pots. To divide the plant, carefully remove it from its pot and locate the suitable place to divide. It would help if you used a sterilized blade to cut the plant at its rhizome's base, ensuring each division has two to three stalks and the roots remain intact. Plant each division in sterilized planting medium or pots with a nutrient-rich soil mixture. Water the plants regularly and keep them in a warm and humid environment until they are well established.
Propagation through Offsets
Orchids produce offsets or plantlets as natural clones of the mother plant. These offsets, or keikis, are genetically identical to the parent plant, making them an excellent propagation method. You can detach the offsets when they have developed a few leaves and roots by using a sterilized blade to sever them from the mother plant. The offsets can be potted up in small pots containing sterile, well-draining planting medium, and kept warm and humid. Water the offsets regularly and wait for them to establish and grow into mature plants before transplanting them.
Disease and Pest Management for Satyrium Buchananii Schltr.
