The essential oil extracted from the leaves of the plant is also used in aromatherapy and as a flavoring agent in the food industry. Additionally, the plant is also grown as an ornamental plant in gardens due to its attractive foliage and flowers. Pelargonium lobatum is also used in traditional medicine to treat a variety of ailments, including respiratory infections and skin irritations.
Light
Pelargonium lobatum requires bright, indirect sunlight to grow properly. It should be placed in a location that receives sunlight for several hours a day. Exposure to direct sunlight can harm the plant and cause the leaves to wilt or turn brown.
Temperature
This plant grows well in warm temperatures between 60-80°F (15-27°C). During the winter, it is best to keep the plant in a location that is not exposed to cold drafts or temperatures below 40°F (4°C). If the temperature drops too much, the leaves may drop.
Soil
The ideal soil for Pelargonium lobatum should be well-drained and have a slightly acidic pH (between 6.0 and 6.5). A good mixture is equal parts peat moss, sand, and perlite. Avoid soil that is too heavy or clay-based because it does not allow water to drain properly and may lead to root rot.
Cultivation Methods
Pelargonium lobatum, also known as storksbill, is a delicate plant that grows well indoors and in a garden setting. The plant thrives in a well-draining potting mix with plenty of sunlight. Ensure that the pot or planting area has excellent drainage to avoid waterlogging which will hurt the plant.
Watering Needs
The plant needs enough water to stay alive but doesn't like to sit in a soggy pot. Water the plant when the soil is dry to the touch. The plant requires watering about once a week, but the schedule varies based on the climate, humidity, and temperature. During the winter months, reduce watering since the plant won't use up as much water.
Fertilization
Fertilize the plant every 2-3 weeks using a balanced liquid fertilizer that has equal parts of nitrogen, phosphorus, and potassium. Ensure to follow the instructions on the package for dosage and frequency. But do not fertilize when transplanted to a new pot or area. Avoid fertilization during winter dormancy when the plant is not actively using nutrients.
Pruning
Prune Pelargonium lobatum by removing wilted, yellow, or dead leaves and stems regularly. Regular pruning helps the plant maintain its shape and vigor. You can trim the plant several times during the growing season to encourage bushy growth. While trimming, be careful not to cut too far into the green stems and leaves.
Propagation of Pelargonium lobatum (Burm.f.) L'Hér.
Pelargonium lobatum (Burm.f.) L'Hér. can be propagated by various methods including seeds, stem cuttings, and division.
Propagation by Seeds
Seeds of Pelargonium lobatum (Burm.f.) L'Hér. can be sown in the fall or early spring. The seeds should be sown in well-draining soil and kept moist. Germination usually occurs within two weeks and seedlings can be transplanted after a few months of growth.
Propagation by Stem Cuttings
Stem cuttings can be taken from healthy, mature plants of Pelargonium lobatum (Burm.f.) L'Hér. during the summer months. Cuttings should be approximately 10-15cm long and taken from the tip or middle of the stem. Remove the bottom leaves and dip the cut end in rooting hormone before planting in well-draining soil. Keep the soil moist and the cutting in a warm, bright location. Roots should develop within a few weeks and the new plant can be transplanted after a few months of growth.
Propagation by Division
Pelargonium lobatum (Burm.f.) L'Hér. can also be propagated by division. This method is best done in the spring when the plant is beginning to grow. Carefully separate the roots and replant each section in its own pot or area in the garden. Water the newly planted sections regularly until they establish their own root systems.
Disease Management
Pelargonium lobatum can be susceptible to several fungal and bacterial diseases, including botrytis blight, leaf spot, and bacterial soft rot. To prevent these diseases, avoid overwatering the plant and ensure proper drainage. Additionally, maintaining good air circulation around the plant can help prevent fungal diseases. If these diseases do occur, remove and dispose of infected plant parts and treat with a fungicide or bactericide according to the product label directions.
Pest Management
Several pests can also affect Pelargonium lobatum, including spider mites, mealybugs, and aphids. Regularly inspect the plant for signs of pests, such as webbing, tiny insects, or yellowing leaves. To manage spider mites, use a fine spray of water to remove them, or treat with an insecticidal soap or horticultural oil. For mealybugs and aphids, remove the pests manually or use insecticidal soap or horticultural oil to control them. Additionally, sticky traps can be effective in trapping flying insects that may feed on the plant.
