Cultivation
Lecanora epanora (Ach.) Ach. is a lichen species found in arctic and alpine regions. It grows on rocks, soil, and tree barks. To cultivate this lichen in your garden or greenhouse, you need to mimic its natural growing conditions.
Start by creating a substrate of rocks, gravel, and sand in a shallow container. Place the container in a shaded area with good air circulation. It is best to grow this lichen outdoors, but you can also grow it inside if you can provide the same growing conditions.
Source a small amount of Lecanora epanora (Ach.) Ach. from established colonies. Gently brush the thallus on the substrate and moisten it with distilled water. Keep the substrate moist but not waterlogged. Avoid direct sunlight and keep it in a shaded area. Lichen colonies grow slowly, so it may take months before a visible thallus appears.
Watering Needs
Water is crucial for lichen growth, but Lecanora epanora (Ach.) Ach. is adapted to survive in the arctic and alpine regions with limited water. It is an opportunistic species that can absorb water and nutrients from snow and rain. Therefore, you need to be careful with watering this lichen.
Only water the Lecanora epanora (Ach.) Ach. substrate when it is dry to the touch. Do not waterlog the substrate as it can damage the lichen. Use distilled water or rainwater as tap water may contain chemicals that can harm the lichen.
Fertilization
Lichen does not require traditional fertilization as they produce their food through photosynthesis and absorb nutrients and minerals from their environment. However, adding some essential nutrients to the substrate can benefit lichen growth.
You can add a small amount of nitrogen, phosphorus, and potassium to the substrate to enhance lichen growth. Use organic fertilizers, such as bone meal or fish emulsion, and a dilute solution. Apply the fertilizer once a year in the growing season.
Pruning
Lichen does not require pruning as they do not have roots or stems. However, you may need to remove any debris or fallen leaves from the substrate to prevent them from blocking sunlight and air circulation.
If you notice any damaged or diseased thallus, remove it carefully with a soft brush or tweezers. Avoid removing the entire thallus, as it may disrupt the colony growth.
Propagation of Lecanora Epanora
Lecanora epanora (Ach.) Ach., commonly known as the "powdery sunburst lichen," is a type of foliose lichen that grows on rocks and trees in temperate and arctic areas. It is a popular plant used in ornamental horticulture because of its vibrant yellow-green appearance and suitability for outdoor gardens.
Vegetative Propagation
The most common method of propagating Lecanora epanora is through vegetative propagation. This involves taking a small portion of the lichen thallus and transplanting it to a new location. The best time to transplant is in the spring when the plant is actively growing.
To propagate by vegetative means, one should gently remove a small portion of the thallus from an established Lecanora epanora plant. This can be done by carefully detaching a small section with a sharp blade. The cutting should then be placed in a container filled with damp sphagnum moss.
Once the cutting is securely in place in the moss, it should be kept in a cool area with indirect light for at least four to six weeks. During this time, the cutting should not be watered, as this may cause it to rot. After the plant has established roots, it can be carefully transplanted into a pot or directly into the ground.
Asexual Propagation
In addition to vegetative propagation, Lecanora epanora can also be propagated asexually through soredia. Soredia are small, powdery structures that grow on the surface of the thallus. These structures are made up of both fungal and algal cells and can give rise to new plants if they land in a suitable environment.
To propagate using soredia, one should gently remove a small portion of the thallus that contains soredia and place it on a suitable substrate. The substrate often used is a piece of bark or other natural material that the lichen would normally grow on.
The substrate should then be placed in a plastic bag and left in a cool area with indirect light for several weeks. During this time, the soredia should begin to grow into new plants. Once the plants have established themselves, they can be carefully transplanted into a pot or directly into the ground.
Overall, Lecanora epanora is a hardy and easy-to-grow plant that can be propagated using a variety of methods. Whether propagating through vegetative means or using soredia, it is important to provide the plant with a suitable environment and adequate care to ensure successful growth.
