Pelargonium oreophilum Schltr. Description
Pelargonium oreophilum Schltr., also known as the Mountain Geranium, is a perennial flowering plant native to the Drakensberg Mountains in South Africa. It is a member of the Pelargonium genus, which contains around 280 species of flowering plants in the Geraniaceae family.
Common Names
The plant is commonly referred to as Mountain Geranium, Drakensberg Geranium, and Bergbos Geranium.
Appearance
Pelargonium oreophilum Schltr. is a small, clumping herbaceous perennial that grows up to 30 cm tall. The leaves are deeply lobed, around 5 cm wide, and are hairy on both sides. The flowers are held on long, slender stems and are usually pink or white in color. They are characterized by their unique, asymmetrical shape with two upper petals and three lower petals. The flowers bloom from late spring to early summer.
Uses
Pelargonium oreophilum Schltr. is primarily used as an ornamental plant due to its attractive foliage and flowers. It is commonly grown in gardens and as a potted plant. The leaves and flowers can also be used to make tea with a slightly sweet flavor. In traditional South African medicine, the plant is used to treat diarrhea and stomach ailments.
Light Requirements
Pelargonium oreophilum Schltr. prefers to grow in full sunlight or in partly shaded locations. However, it is essential to make sure the plant is not exposed to harsh, direct sunlight for extended periods as this can lead to leaf burn. It is, therefore, recommended to provide at least 4-6 hours of direct sunlight daily.
Temperature Requirements
The temperature suitable for the growth of Pelargonium oreophilum Schltr. falls within the range of 40-85°F (5-30°C). This plant grows well in both cool and warm temperatures. Temperatures below 40°F (5°C) harm the plant, leading to foliage and stem damage. However, if it is grown in temperatures above 85°F (30°C), it is crucial to ensure that it receives sufficient watering consistently.
Soil Requirements
Pelargonium oreophilum Schltr. prefers slightly acidic to alkaline soils with a pH level ranging between 5.8-7.0. The plant requires well-draining soil that retains a decent amount of moisture without remaining damp. A 1:1:1 or 2:1:1 ratio of Potting soil: Perlite: Peat moss should be prepared before planting. This plant thrives in locations with rich, fertile soils, so it is recommended to add organic supplements like compost, bone meal, or slow-release fertilizer to maintain its quality.
Cultivation methods:
Pelargonium oreophilum Schltr., also known as mountain pelargonium, is a perennial shrub that is indigenous to South Africa. It prefers to grow in temperate climates with mild summers and cool winters. The plant develops best in a well-drained soil mix comprising sand, loam, and peat-based compost that is slightly acidic.
Mountain pelargonium thrives in a bright location where it can receive at least six hours of sun every day. It will require protection from direct sun during peak hours to prevent scorching and sunburns.
Watering needs:
Pelargonium oreophilum Schltr. thrives in moist, but not damp soil. Water your plant consistently to keep the soil moist. Monitor the soil regularly to ensure it does not become waterlogged since this will cause the roots to rot. Avoid overhead watering, especially during cold seasons as this can lead to fungal infections.
Fertilization:
Mountain pelargonium requires sufficient nutrients to produce vibrant and healthy flowers. Add fertilizer with a balanced NPK ratio of 20-20-20 or 24-8-16 every two to four weeks throughout the growing season. Decrease the amount of fertilizer during the winter months.
Pruning:
Mountain pelargonium thrives with annual pruning in the springtime. Prune the plant back to encourage new growth, maintain its desired shape, and promote abundant flowering. Remove yellowed and dead leaves and spent blooms to maintain a neat appearance and prevent the spread of diseases.
Propagation of Pelargonium oreophilum Schltr.
Pelargonium oreophilum Schltr. can be propagated by several methods, including seed propagation, stem cuttings and division.
Seed propagation
The easiest way to propagate Pelargonium oreophilum Schltr. is by seed. The seeds should be sown in well-draining soil and kept moist. The soil must be kept warm, ideally between 18-24°C, and the seeds should germinate within 2-4 weeks. Once the seedlings emerge, the pot can be moved to a cooler location and given bright, indirect light. After the seedlings have grown to a reasonable size, they can be potted on into individual pots.
Stem cuttings
Propagation by stem cuttings is also possible with Pelargonium oreophilum Schltr. The best time to take cuttings is in early spring when new growth emerges. The cuttings should be taken from non-flowering shoots, and the bottom leaves should be removed. The cuttings should be dipped in rooting hormone and planted in well-draining soil. The pot should be kept moist and the cuttings should be given bright, indirect light. After 4-6 weeks, the cuttings should have rooted and can be potted in individual pots.
Division
Pelargonium oreophilum Schltr. can also be propagated by division. This is best done in spring when the plant is actively growing. The plant should be carefully lifted from the soil and the root ball gently separated. The divided plant should be replanted in well-draining soil and kept moist. The plant may require frequent watering until it is established.
Disease and pest management for Pelargonium oreophilum Schltr.
Pelargonium oreophilum Schltr. is a hardy plant that is usually resistant to diseases and pest infestations. However, there are some common pests and diseases that might affect the plant. It is crucial to know about these issues and how to manage them effectively.
Common diseases affecting Pelargonium oreophilum Schltr.
One of the most common diseases that affect Pelargonium oreophilum Schltr. is the Botrytis blight. This disease is caused by the fungus Botrytis cinerea, which can result in the production of gray mold on the plant's leaves and stems. To manage this disease, remove the affected parts of the plant and apply a fungicide as per the instructions on the package.
Another common disease that might affect Pelargonium oreophilum Schltr. is the Pythium root rot. This disease is caused by the Pythium fungus, which might result in the rotting of the roots and the plant's death. To manage this disease, avoid overwatering the plant and ensure that the soil is well-draining. You can also apply a fungicide to protect the plant from fungal infections.
Common pests affecting Pelargonium oreophilum Schltr.
The most common pest that might infest Pelargonium oreophilum Schltr. is the whitefly. These tiny insects usually feed on the plant's sap, resulting in the plant's weakening, yellowing, and dying. To manage this pest, use yellow sticky traps to capture the insects, remove the infected leaves, and apply an insecticide as per the manufacturer's instructions. Also, consider introducing beneficial insects such as ladybirds and lacewings.
Another common pest that might affect Pelargonium oreophilum Schltr. is the spider mite. This pest usually appears in dry and hot conditions, resulting in the yellowing and browning of the leaves. To manage this pest, increase the plant's humidity levels by misting its leaves with water, remove the infected parts of the plant and apply an insecticide as per the manufacturer's instructions.
In conclusion, it is essential to take care of Pelargonium oreophilum Schltr. to ensure that it remains healthy. Regularly monitor the plant for any pest or disease infestations and take the appropriate action immediately. With proper care and management, Pelargonium oreophilum Schltr. will thrive and remain healthy.
