It is believed that the plant has astringent and antiseptic properties, and its infusion is used as a gargle for treating sore throats.
Furthermore, the Hairy Geranium is also grown as an ornamental plant due to its beautiful flowers. It is a popular choice for rock gardens, borders, and ground covers. Its long flowering season and its ability to tolerate dry soil and partial shade make it ideal for planting in gardens.
Light Requirements:
Geranium pilosum Cav. is a sun-loving plant and requires full sunlight for at least 6 hours per day for healthy growth. It cannot tolerate shading or low light conditions. Therefore, it is best to grow this plant in areas with exposure to direct sunlight.
Temperature Requirements:
Geranium pilosum Cav. grows well in warm temperatures. The ideal temperature range for this plant is between 20-30°C. It cannot tolerate freezing temperatures or frost. Therefore, it is essential to protect the plant from cold weather by covering it with a blanket or moving it indoor during winter.
Soil Requirements:
Geranium pilosum Cav. prefers well-drained, slightly acidic to neutral soil. It grows well in sandy or loamy soil that is rich in organic matter. The soil should maintain a pH range between 6.0 to 7.0. Ensure good drainage for the soil to prevent root rot. Additionally, adding compost and organic fertilizers can improve the nutrient content and water-holding capacity of the soil.
Cultivation methods
Geranium pilosum Cav. is a versatile plant that can thrive in a variety of growing conditions. It's ideal to cultivate the plant in well-drained soil with a pH range of 6.5 to 7.2. You can plant the geranium in full sun or partial shade, but it performs best in a spot that receives at least six hours of direct sunlight each day. Geraniums can be grown from seed or cuttings. If you're growing from seed, plant them in early spring, and if you're using cuttings, propagate them at the beginning of the growing season.
Watering needs
Geraniums require regular watering but can't tolerate overwatering. Water the plant only when the soil feels dry to the touch. Avoid getting water on the leaves as this can cause fungal growth. It's also essential to water the plant deeply, ensuring the water reaches the root zone, as this promotes healthy root growth.
Fertilization
To boost the growth and flowering of Geranium pilosum Cav., feed the plant with a balanced fertilizer in the early stages of the growing season. Alternatively, you can apply a slow-release fertilizer that will provide the plant with a steady supply of nutrients throughout the season. Be sure not to overfeed the plant; too much fertilizer can lead to issues such as leggy growth and reduced flower production.
Pruning
When growing Geranium pilosum Cav., regular pruning is beneficial to maintain the plant's shape, promote bushier growth, and encourage more flowering. Deadheading spent blooms regularly will also encourage new flower growth. You can also prune the plant to remove any damaged or diseased leaves, stems, or flowers. Pruning should be done in early spring or late autumn when the plant is dormant, allowing it to produce new growth in the upcoming season.
Propagation of Geranium pilosum Cav.
Geranium pilosum Cav. is a perennial plant that belongs to the geranium family (Geraniaceae). It is commonly known as hairy geranium, owing to the dense, hairy covering on its stems and leaves. The plant is native to South America and is often grown as an ornamental plant in gardens due to its attractive flowers and foliage.
Propagation Methods
Geranium pilosum Cav. is an easy-to-propagate plant that can be propagated by several methods:
- Seed propagation: Geranium pilosum Cav. produces seeds in small capsules, which can be collected once they have dried out and turned brown. The seeds can then be sown indoors in seedling trays or directly outside in a prepared bed in the spring. Seeds should be covered with a thin layer of soil and kept moist until they germinate, which usually takes 10-20 days.
- Division: The plant can also be propagated by dividing the clumps of the plant in the spring. The clumps should be carefully dug up and separated into smaller plants, each with its own roots. These individual plants can then be potted up or planted directly in the garden.
- Cuttings: Geranium pilosum Cav. can be propagated by taking stem cuttings in the spring or summer. Cuttings should be taken from the tips of the shoots and should be around 10-15 cm long. Remove any leaves from the bottom half of the cutting and dip the cut end into rooting hormone. Plant the cuttings in a pot filled with a well-draining growing medium, and keep them out of direct sunlight until they have rooted.
Overall, Geranium pilosum Cav. is a relatively easy plant to propagate. Whether through seed, division, or cuttings, any gardener can expand their garden with this beautiful plant.
Disease and Pest Management for Geranium Pilosum Cav.
Geranium pilosum Cav. is a hardy plant that is resistant to many pests and diseases. However, like any other plant, it can still fall prey to some harmful organisms if not taken care of properly. Here are some common diseases and pests that might affect the plant and ways to manage them:
Diseases
Fungal Leaf Spot: Fungal leaf spot is a common disease that affects geraniums. It is characterized by small, circular or irregular shaped spots on the leaves. To manage this disease, remove the infected parts of the plant and ensure to keep the plant in a well-ventilated area with enough sunlight exposure. You may also apply fungicides to control the disease.
Crown Rot: This disease is caused by soil-borne fungi and is characterized by brown roots, wilted leaves, and plant decay. To avoid this disease, ensure that the plant is well-drained and not overwatered. Additionally, you can use fungicides to manage the disease.
Pests
Aphids: Aphids are small insects that suck out the sap from the plant, causing it to weaken and possibly die. They can easily be identified by their small size and pear-shaped bodies. To manage aphids, you can spray the plant with neem oil or insecticidal soap.
Spider Mites: Spider mites are tiny pests that suck the plant's moisture and nutrients, causing it to dry out. They cause damage by making tiny spots on the leaves and spreading rapidly. To control spider mites, you can spray the plant with insecticides or neem oil. Remove heavily infested plants to prevent the pests from spreading to other plants.
Root-knot Nematodes: Root-knot nematodes are microscopic worms that parasitize the plant's roots, causing swellings and galls. This interferes with the plant's ability to absorb water and nutrients. To manage root-knot nematodes, practice crop rotation and soil sterilization using chemicals or steam.
By following these precautions and practices, you can manage common diseases and pests that might affect your Geranium Pilosum Cav. plant effectively.
