Light Requirements
Mycoblastus affinis (Schaerer) Schauer thrives in full sunlight to partial shade. However, it prefers areas with partial shade due to the harsh effect of direct sunlight on its leaves. It can tolerate a low amount of shade but performs poorly in heavily shaded areas. Therefore, it is best to grow it in areas where it can receive sunlight for at least a few hours each day.
Temperature Requirements
The plant can tolerate a broad temperature range. However, it prefers a cool and moist environment with temperatures ranging from 10°C to 18°C (50°F to 64.4°F). It can survive in high temperatures of up to 30°C (86°F) but does not grow well under such conditions. Its high-temperature limit is approximately 32°C (89.6°F), above which it cannot survive.
Moisture and Soil Requirements
Mycoblastus affinis (Schaerer) Schauer prefers moist and well-drained soil. The soil should be rich in nutrients and slightly acidic with a pH ranging from 5.5 to 6.5. The plant forms a symbiotic relationship with fungi, and therefore the soil should contain an adequate supply of mycorrhizae. The plant can grow on a wide variety of substrates, including rocks, bark, and soil. Moisture is critical for the survival of this plant, and it cannot survive in dry conditions. It is best grown in areas with moderate to high humidity.
Cultivation Methods
Mycoblastus affinis is a slow-growing plant that requires a specific substrate for optimal growth. It is recommended to cultivate the plant in a mixture of mineral and organic substrates. The plant also prefers well-draining soil. The ideal pH of the substrate should be acidic to neutral. The plant requires moderate to low sunlight, so place it in a semi-shady location.
Watering Needs
Mycoblastus affinis requires regular watering to keep the soil damp. It is necessary to irrigate the plant periodically, depending on the prevailing weather conditions. In the summer season, the plant requires relatively more watering, while in the winter season, the plant requires less watering. Over-watering should be avoided as it can result in root rot, which is detrimental to the plant's growth.
Fertilization
Fertilization can be done once or twice a year, preferably during the growing season. Organic fertilizers are highly recommended as synthetic fertilizers can damage the plant's root system. Over-fertilization should be avoided as it can lead to the accumulation of salts, which can harm the plant's growth.
Pruning
Mycoblastus affinis does not require extensive pruning. The plant should only be pruned to maintain its shape or remove any dead or diseased stems. As with most plants, it is recommended to use a sterilized pruning tool to prevent the spread of disease or infections.
Propagation of Mycoblastus affinis (Schaerer) Schauer
Mycoblastus affinis (Schaerer) Schauer can be propagated through different methods, including division, cuttings, and spores.
Division
One of the easiest and most common ways to propagate Mycoblastus affinis is by division. This method involves separating the plant into two or more sections, each with its own root system. The best time to do this is in the spring, just before new growth begins.
To divide the plant, gently lift it out of the soil and use a clean, sharp knife to cut through the root ball. Each section should have a good amount of roots and at least one stem with leaves. Replant each section in a new pot or location in the garden, water thoroughly, and keep it in a warm, bright place.
Cuttings
The propagation of Mycoblastus affinis through stem cuttings is also possible. Choose a healthy stem that has several leaves, and cut it with a clean, sharp knife just below a leaf node. Remove the lower leaves, leaving only the top ones, and dip the end of the stem in rooting hormone powder.
Plant the stem in a pot or container with moist, well-draining soil. Cover the pot with a plastic bag, and keep it in a warm and bright location, out of direct sunlight. After about two weeks, roots should start to form, and new growth will emerge from the top. Once the plant is well-established, it can be transplanted to a larger container or the garden.
Spores
Mycoblastus affinis can also be propagated by spores. This method is more time-consuming and requires more attention to detail than the previous methods. Collect the spores from mature fronds by placing them in a paper bag and shaking them gently.
Fill a container with sterile, well-draining soil, and sprinkle the spores evenly on the surface. Cover the container with a clear plastic bag or lid and keep it in a warm, humid location. The spores can take several weeks to germinate, and once they do, they will appear as tiny green plants.
After the plants have produced several fronds, they can be transplanted to a larger container or the garden.
