The Oak Disco lichen can tolerate different types of bark and has been found on the bark of oak, beech, birch, and other tree species. However, it prefers trees with smooth bark and minimal abrasions that can damage the lichen.
Cultivation methods for Calicium quercinum Pers.
Calicium quercinum Pers. is a slow-growing plant that requires specific conditions to thrive. To cultivate this plant successfully, it is essential to provide it with the right growing medium, light, and temperature conditions.
Firstly, start by selecting a well-draining growing medium that mimics the plant's natural habitat. This medium should consist of equal parts of peat moss, perlite, and bark. Ensure the medium is moist but not too wet.
The plant prefers bright to medium light. Therefore, place it in an area that receives ample sunlight, but not direct sunlight. Too much direct sunlight can damage the plant.
Finally, ensure the temperature around the plant is between 60 to 75°F. That temperature range is perfect for Calicium quercinum Pers. to grow. Always ensure the plant is far from drafts, as they can negatively affect the plant's growth.
Watering needs for Calicium quercinum Pers.
Watering is an essential aspect of caring for Calicium quercinum Pers. The plant prefers moist soil at all times but cannot withstand waterlogged soil.
During the growing season, water your plant generously, ensuring the topsoil remains moist. However, be careful not to overwater the plant to prevent rotting roots. Conversely, during the dormant season, reduce watering to once every two weeks.
A friendly reminder is to always water the plant at the base to prevent leaves' water damage. You can use a watering can with a long spout or a hose to achieve this.
Fertilization of Calicium quercinum Pers.
To keep your Calicium quercinum Pers. plant healthy, regular fertilization is essential. However, be cautious not to overfertilize, as it may lead to salt accumulation, damaging the roots.
Apply a balanced liquid houseplant fertilizer twice per month from the beginning of spring until the end of summer. During fall and winter, reduce fertilization to once per month. Always follow the manufacturer's instructions when applying fertilizer to the plant.
Pruning of Calicium quercinum Pers.
Calicium quercinum Pers. does not require significant pruning. However, you might want to trim off old or yellow leaves using a pair of sharp and clean scissors.
If the plant becomes too leggy, you can trim the top part off, promoting a bushier plant. Deadheading, which involves removing spent and dead flower heads, is also necessary to redirect energy to new growth.
A friendly reminder is to clean your pruning shears before and after each use to prevent the spread of diseases to the plant.
Propagation of Calicium quercinum Pers.
Calicium quercinum Pers. is a lichenized fungus that grows on oak trees, rocks, and soil surfaces. It can also be propagated artificially using various methods. The following are the propagation methods for Calicium quercinum Pers.
Method 1: Soredia propagation
Soredia are powdery or granular reproductive structures that contain both algal and fungal components. They are mainly responsible for the vegetative reproduction of lichens, including Calicium quercinum Pers. To propagate the plant through soredia, follow these simple steps:
- Select healthy Calicium quercinum Pers. that has a good density of soredia.
- Collect the soredia from the surface of the thallus using a brush or forceps.
- Transfer the soredia to a sterile piece of substrate, such as agar or bark, and press them lightly into the surface.
- Moisten the substrate and incubate it in a humid environment with moderate light.
- The soredia will germinate and develop into young thalli that can be used to establish new colonies of Calicium quercinum Pers.
Method 2: Fragment propagation
Fragment propagation involves breaking apart the thallus of Calicium quercinum Pers. into smaller pieces and using them to establish new colonies. The steps for fragment propagation are as follows:
- Collect healthy Calicium quercinum Pers. thalli from their natural habitat or a culture.
- Carefully break the thalli into smaller pieces using sterilized tools.
- Place the thallus fragments onto a suitable substrate, such as bark or rocks, and press them lightly into the surface.
- Moisten the substrate, then incubate the fragments in a humid environment with moderate light.
- The fragments will grow and fuse together to form new colonies of Calicium quercinum Pers.
Method 3: Spore propagation
Spore propagation involves collecting and germinating spores produced by Calicium quercinum Pers. The steps involved in spore propagation are:
- Collect mature Calicium quercinum Pers. thalli that have fruiting bodies.
- Harvest the fruiting bodies and place them onto a clean, dry surface to allow the spores to mature.
- Collect the mature spores and place them onto a suitable substrate, such as agar or bark.
- Moisten the substrate and incubate it in a humid environment with moderate light.
- The spores will germinate and grow into young thalli that can be used to establish new colonies of Calicium quercinum Pers.
These are the different methods that can be used for the propagation of Calicium quercinum Pers. It is important to maintain sterile conditions and appropriate environmental conditions for optimal results.
