It has been traditionally used for treating sore throat, tonsillitis, and respiratory infections. The plant's essential oil is used in aromatherapy to relieve stress, anxiety, and depression. Moreover, it is used in perfumery to add a lemon-like scent to fragrances.
Cultivation:
The golden storksbill is best grown in well-draining soil with full sun or partial shade. It is a drought-tolerant plant that requires minimal water and fertilization. The plant can be propagated through seeds or stem cuttings, which should be taken in autumn. It is a hardy plant that can withstand mild frost, making it a suitable garden plant for mild temperate climates.
Light Requirements
Pelargonium auritum (L.) Willd. var. auritum thrives in bright, direct sunlight. It should receive at least six hours of sunlight every day. However, it can also tolerate partial shade in extremely hot climates.
Temperature Requirements
Pelargonium auritum (L.) Willd. var. auritum prefers warm to hot temperatures, with an ideal range of 20-30°C (68-86°F). It cannot survive in extreme cold temperatures and should be protected from frost.
Soil Requirements
The ideal soil for Pelargonium auritum (L.) Willd. var. auritum is well-draining soil with a pH range of 6.0-7.0. It should be rich in organic matter, and adding compost or other organic materials can be beneficial. The plant prefers slightly moist soil, but it should not be waterlogged as this can lead to root rot.
Cultivation methods
Pelargonium auritum (L.) Willd. var. auritum is a perennial herb that requires full sunlight and moderate temperatures to grow. To cultivate this plant, you should choose a well-draining soil that is rich in nutrients and is slightly acidic. The pH level of the soil should be between 5.5 and 6.5. You can grow Pelargonium auritum (L.) Willd. var. auritum in both pots and open fields.
Watering needs
Pelargonium auritum (L.) Willd. var. auritum prefers moderate watering, and the soil should never be soggy. Overwatering can cause root rot and kill the plant. You should water the plant when the topsoil is dry, but make sure not to let the soil dry out completely. You can check the soil moisture level by inserting a finger into the soil several centimeters deep, and if the soil feels dry to the touch, then it's time to water the plant.
Fertilization
To enhance the growth of Pelargonium auritum (L.) Willd. var. auritum, you should fertilize the plant regularly. You can use a balanced granular fertilizer with a ratio of 10:10:10, or a water-soluble fertilizer with a ratio of 20:20:20. Fertilize the plant once every two weeks during the growing season, which is from spring to late summer. You may reduce the frequency to once a month during autumn and winter.
Pruning
Pruning Pelargonium auritum (L.) Willd. var. auritum can help tidy up the plant and encourage new growth. You should prune the plant in late winter or early spring, just before the growing season begins. To prune the plant, use sharp, clean pruning shears and cut off any dead or damaged branches. You may also remove some of the older branches to promote new growth.
Propagation of Pelargonium auritum (L.) Willd. var. auritum
Pelargonium auritum (L.) Willd. var. auritum, commonly known as the golden-leaved pelargonium, is a beautiful and popular ornamental plant that can be propagated through various methods.
Seed Propagation
The easiest and most common method of propagating Pelargonium auritum is through seeds. Seeds are readily available and can be sown directly on the soil surface or lightly covered. It is preferable to start seeds indoors in a warm and well-lit area. The seeds will germinate in 1-2 weeks, and the seedlings can be transplanted into individual pots when they are 2-3 inches tall.
Cuttings Propagation
Pelargonium auritum can also be propagated through stem cuttings. Late spring or summer is the ideal time for taking cuttings. Select a stem that is healthy and free from any diseases or pests. The cutting length should be roughly 4-6 inches long, with at least two to three nodes present. Remove the lower leaves and dip the cut end in rooting hormone powder. Insert the cuttings in a container filled with well-draining potting mix, and cover it with a plastic bag to create a humid environment. Keep the soil moist and remove the bag after two weeks once the cutting has developed roots.
Division Propagation
Pelargonium auritum can also be propagated through division. This method is typically performed during the spring season when the plant starts to grow actively. To divide the plant, carefully lift the entire plant out of the pot or garden and separate the root ball into several sections, ensuring that each section has at least one healthy stem and root system. replant the divided sections in individual pots or desired locations.
Pelargonium auritum is easy to propagate through different methods, and with proper care and attention, the propagated plants grow well and produce stunning blooms that will brighten up any garden or indoor space.
Disease Management
Pelargonium auritum (L.) Willd. var. auritum is susceptible to various diseases that may affect its growth, development, and productivity. Some of the common diseases that might affect the plant are:
- Botrytis blight: This is a fungal disease that causes gray mold on the plant's leaves, stems, and flowers. Infected plant parts become brown and mushy, and the disease can spread quickly in humid or wet weather conditions. To manage this disease, remove and destroy infected plant parts, avoid overcrowding plants, and ensure good air circulation and sanitation. You can also use fungicides to control the disease.
- Leaf spot: This fungal disease causes brown spots on the plant's leaves, which may coalesce and cause leaf drop. The disease is favored by high humidity and temperatures above 21°C. To manage this disease, remove and destroy infected leaves, water the plants early in the day to allow the foliage to dry, and avoid overcrowding plants.
- Powdery mildew: This is a fungal disease that causes a white, powdery coating on the plant's leaves, stems, and flowers. The disease weakens the plant and reduces its productivity. To manage this disease, improve air circulation around the plant, avoid overhead watering, and remove and destroy infected plant parts. You can also use fungicides to control the disease.
Pest Management
Pelargonium auritum (L.) Willd. var. auritum is also susceptible to various pests that may damage the plant and reduce its productivity. Some of the common pests that might affect the plant are:
- Aphids: These small, soft-bodied insects feed on the plant's sap, causing leaves to curl and distort. To manage these pests, remove them by hand, spray the plant with a strong jet of water, or use insecticidal soap or neem oil.
- Spider mites: These tiny pests feed on the plant's sap and cause yellowing, stippling, and leaf drop. They are common in hot, dry conditions. To manage spider mites, increase humidity around the plant, remove and destroy infected plant parts, and use insecticidal soap or neem oil.
- Thrips: These tiny, slender insects feed on the plant's sap and cause deformed flowers and leaves. To manage thrips, remove and destroy infected plant parts, use blue or yellow sticky traps, or use insecticidal soap or neem oil.
It is important to monitor your plant regularly for any signs of disease or pests and take appropriate action to manage them promptly. Good sanitation practices, such as keeping the area around the plant clean and removing and destroying infected plant parts, can also help to prevent the spread of disease and pests.
