It can grow on various types of soil, including sandy, loamy, or rocky soils. However, the plant cannot grow in waterlogged soils. Adequate soil moisture is necessary for optimal plant growth, but excess moisture can cause root rot.
Cultivation methods
Candelariella Mull. Arg. plant can be easily grown both outdoors and indoors, as long as the right growing conditions are provided. It prefers well-drained soil and requires a lot of sunshine. If you are planning to grow it indoors, place the pot near the window where it can receive at least 6 hours of sunlight. It can be propagated through cuttings or seeds. It is best to start cultivating the plant in the spring season.
Watering needs
Candelariella Mull. Arg. plant requires moderate watering. It is best to water the plant only when the soil is dry to the touch. Overwatering can lead to root rot, which can be fatal for the plant. It is essential to ensure proper drainage to avoid the risk of waterlogging. During the summer season, it may require more frequent watering as the increased temperatures can cause faster evaporation.
Fertilization
To promote proper growth and keep the plant healthy, it is essential to fertilize it regularly. Candelariella Mull. Arg. plant requires a balanced fertilizer containing equal amounts of nitrogen, phosphorus, and potassium. Fertilize the plant every two weeks during the growing season, but during the dormant season, reduce the frequency of fertilization to once a month.
Pruning
Candelariella Mull. Arg. plant does not require extensive pruning but may need occasional pruning to maintain its shape and size. Cut back any dry or dead branches or leaves as soon as you spot them before they spread to other parts. You can prune stems that have grown too long or are blocking the sunlight from entering the plant's center. Pruning is best done during the dormant season.
Propagation of Candelariella Mull. Arg.
Candelariella Mull. Arg. is a small lichen genus that belongs to the family of Candelariaceae. There are different methods used to propagate the plant.
Vegetative propagation
One of the ways to propagate the plant is through vegetative propagation. This involves taking cuttings from the parent plant and then growing new plants. In Candelariella Mull. Arg., vegetative propagation is done by using soredia or isidia. Soredia are small clusters of cells that detach from the thallus of the parent plant, while isidia are small, branched, and spherical outgrowths that occur on the surface.
To use soredia or isidia for propagation, they are simply collected from the parent plant and then placed in a suitable growing medium. The growing medium should be moist and slightly acidic to allow the soredia or isidia to establish and grow roots. Once the roots grow, new plants will start to grow, which can then be transplanted to their final destination.
Sexual propagation
Another method of propagating Candelariella Mull. Arg. is through sexual propagation. This involves using spore propagation, which is more challenging than vegetative propagation.
To use spore propagation, spores are collected from the parent plant and then placed on a suitable growing medium. The growing medium should be kept moist, and the temperature should be maintained between 15-30 degrees Celsius. Once the spores start to grow, new plants will start to develop, which can then be transplanted to their final destination.
In conclusion, vegetative propagation using soredia or isidia is the best method to propagate Candelariella Mull. Arg. It is easy to do and yields better results than sexual propagation. However, spore propagation can be used for research purposes.
