Overview
Leproloma angardianum, also known as Ovstedal Lichen, is a species of lichen found in the Arctic and subarctic regions of Europe, North America, and Asia. This plant is known for its intricate and delicate appearance, which makes it a popular subject for nature photographers and hikers.
Appearance
Leproloma angardianum has a small, crusty appearance, with a diameter of about 1-2 centimeters. It has a pale bluish-grey or greenish color, with a distinctive pattern of circular or oblong shaped dots. The outer edge of the plant is typically raised, giving it a slightly raised appearance. The fruiting bodies of Leproloma angardianum are also a unique feature, as they appear as small, red dots on the surface of the lichen.
Uses
Although Leproloma angardianum is not known to have any specific medicinal uses, it is commonly used in environmental studies to determine air quality in arctic and subarctic regions. The presence of this plant in certain areas can be an indicator of high air quality.
Additionally, Leproloma angardianum is an important food source for reindeer and other arctic animals. Many indigenous communities also use this plant in traditional medicine and in spiritual practices.
Common names
Leproloma angardianum is commonly known by a number of different names, depending on its location. Some of the most common names include Ovstedal Lichen, Arctic Disk Lichen, and Blue-gray Lichen. In Russia and Scandinavia, it is also known as "pustulose cladonia".
Light Requirements
Leproloma angardianum thrives in moderate to bright light. Direct sunlight should be avoided as it can burn the leaves. A location that receives filtered light or partial shade will provide an ideal growing condition. Artificial light sources can be used to supplement natural light in low light conditions.
Temperature Requirements
This plant prefers a cool to a moderately warm temperature range between 12°C to 22°C (54°F to 72°F). Protection should be provided against extreme temperatures, which can cause damage to the foliage. Winter temperatures below 10°C (50°F) should be avoided.
Soil Requirements
Leproloma angardianum prefers a well-draining mix with a slightly acidic to neutral pH. A soil mix that is rich in organic matter is beneficial in providing the necessary nutrients for the plant's growth. In their natural habitat, they grow on trees and rocks, which indicates that they prefer a growing medium that is not water-logged. A mixture of peat moss, perlite, and fir bark is recommended to provide the required growing conditions.
Cultivation Methods
Leproloma angardianum (Ovstedal) J. R. Laundon is a small, slow-growing subshrub that is native to the southern hemisphere. It prefers a cool, moist climate and grows best in well-draining soil with moderate amounts of organic matter. The plant can be propagated from seed, but it is more commonly propagated from cuttings. To propagate from cuttings, take 2- to 3-inch cuttings during the spring or summer and place them in a well-drained potting mixture. Water regularly and keep the cuttings in a warm, humid spot with indirect sunlight until they root and begin to grow.
Watering Needs
Leproloma angardianum (Ovstedal) J. R. Laundon prefers moist soil, but it does not like to sit in water. Overwatering can lead to root rot and other problems. Water the plant deeply once a week during the growing season and reduce watering during the winter months. Stick your finger an inch into the soil, and only water if the soil feels dry at that depth. You can also mist the foliage occasionally to increase the humidity around the plant.
Fertilization
Leproloma angardianum (Ovstedal) J. R. Laundon does not require a lot of fertilizer, but it will benefit from a light dose of a balanced fertilizer once a month during the growing season. Use a balanced 10-10-10 fertilizer and apply it at half strength to avoid over-fertilizing. Feed the plant every other month during the dormant season.
Pruning
Leproloma angardianum (Ovstedal) J. R. Laundon does not require a lot of pruning, but you can pinch back the tips of the stems in the spring to promote bushier growth. Remove any dead or damaged stems as they occur. Limit pruning to between 25 and 30 percent of the plant's overall size to avoid over-pruning and damaging the plant's health. Prune the plant after it has finished flowering to avoid disrupting the blooming cycle.
Propagation Methods
The Leproloma angardianum (Ovstedal) J. R. Laundon plant can be propagated through various methods, including:
Seed Propagation
Seed propagation is one of the primary methods used to propagate Leproloma angardianum. Collect mature, healthy, and viable seeds from a parent plant. After that, clean and dry them. Sow the seeds in a seedling tray filled with peat moss, perlite, or vermiculite, making sure they're spread uniformly. Cover the planting tray with clear plastic or a clear container to retain moisture and maintain a warm environment. Keep the soil moist and the temperature between 68°F (20°C) and 77°F (25°C).
Cuttings Propagation
Leproloma angardianum plant propagation can also be done through stem cuttings. Choose an actively growing stem that's about 3-4 inches long. Cut it neatly below a node using a sterilized blade. Dip the sliced end in rooting hormones to hasten root development. Place the stem cutting in a pot filled with a rooting mix made up of equal parts sand and peat moss. Water the planting soil and maintain it evenly moist. Set the pot in a warm place in your home and ensure that it gets enough light.
Division Propagation
Division propagation is also possible with Leproloma angardianum. This method is accomplished by dividing the parent plant's roots into two or more portions and replanting them individually into separate containers. Remove the plant from the pot and gently avoid breaking or damaging the roots. Clean off the roots with water, and then separate the plant into two or three parts. Fill each container with fresh potting mixture and press the divisions into the soil so that the top part of the roots is just level with the potting mix's surface. Water thoroughly and maintain the soil damp until new growth emerges.
Disease Management
Leproloma angardianum is generally a healthy and hardy plant. However, it can be affected by a few diseases that can cause significant damage. One of the most common diseases that affect this plant is root rot, which is caused by overwatering and poorly drained soils. To prevent root rot, it is essential to water the plant only when the topsoil is dry. It is also crucial to ensure that the pot has proper drainage to allow excess water to drain.
The second most common disease is powdery mildew, which is caused by fungal infections. It generally appears as white powdery spots on the plant's leaves. To prevent powdery mildew, it is essential to ensure that the plant receives adequate sunlight and air circulation. It is also essential to avoid watering the plant from the top and to remove any infected leaves immediately.
Pest Management
Leproloma angardianum is also susceptible to pests that can attack and damage the plant. One of the common pests is spider mites, which are tiny pests that suck the plant's sap and cause yellowing of leaves and stunted growth. To prevent spider mites, it is essential to ensure that the plant has adequate humidity and to regularly clean and dust the plant's leaves.
The second most common pest is mealybugs, which are tiny and white bugs that feed on the plant's sap. Mealybugs can cause damage to the plant by weakening it and making it more susceptible to other infections. To prevent mealybugs, it is essential to inspect the plant regularly and remove any infected leaves. A common method to manage mealybugs is by using insecticidal soap or neem oil, which will help kill the pests.
In conclusion, preventing diseases and pests is the best approach; however, it is not always possible to avoid them. By following the suggestions above, you can keep your Leproloma angardianum healthy and thriving.
