Common Names
Geranium scabrum is commonly known as Grey-leaved Cranesbill, Rough Cranesbill, or Dove's Foot Geranium.
Uses
The plant has both medicinal and ornamental uses. Its root and leaves were traditionally used to treat various ailments such as diarrhea, bleeding, and inflammations. The plant is also a popular ornamental garden plant due to its attractive, pink flowers that bloom for a long time in late spring and summer.
General Appearance
Geranium scabrum L. is a perennial herbaceous plant that can grow up to 50 centimeters in height. It has a stem that is hairy and grooved, with leaves that are deeply lobed and greyish-green in color. Its flowers are pink in color, with five petals that have a darker pink vein running down the center. The plant prefers to grow in rocky or gravelly soils, and it is often found growing in dry meadows, hedgerows, and along roadsides.
Light Requirements
The plant Geranium scabrum L. typically thrives in full sun to partial shade. To achieve optimal growth, the plant requires an average of six hours of direct sunlight per day. In areas with intense heat, the plant may benefit from partial shade during the summer months.
Temperature Requirements
Geranium scabrum L. grows well in moderate temperatures between 65 and 75°F. During the winter months, the plant may require protection from freezing temperatures lower than 32°F. The plant can withstand high temperatures, but it may display signs of heat stress if exposed to prolonged hot weather conditions.
Soil Requirements
The plant Geranium scabrum L. prefers well-draining soils that are rich in organic matter. The soil pH should range between 6.0 and 7.5. The plant may struggle in soils that are compacted or heavy in clay content. It is recommended to amend the soil with organic material, such as compost or aged manure.
Cultivating Geranium Scabrum L.
Geranium Scabrum L. is a hardy plant and can be easily cultivated in a variety of growing conditions.
Watering Needs
This plant requires consistent moisture, but make sure that it does not sit in water, as this can cause root rot. It is better to water the plant less frequently but deeply to promote deep root growth. Check the moisture level regularly and water the Geranium Scabrum L. plant when the top inch of soil is dry.
Fertilization
To encourage growth and flowering, use a balanced fertilizer, with an N-P-K ratio of 10-10-10, once a month during the growing season. Avoid fertilizing the plant during winter or when it is not actively growing.
Pruning
Regular pruning is recommended for Geranium Scabrum L. to promote bushy growth and maximize the flowering period. Cut back the plant halfway in mid-summer to encourage second blooming. Deadhead flowers regularly to encourage further shoots and blossoms.
Propagation of Geranium scabrum L.
Geranium scabrum L. can be propagated through various methods depending on the grower's purpose. Some of the propagation methods include:
Seed Propagation
The seeds of Geranium scabrum L. can be sown directly into the soil in spring, summer or early fall. Before sowing, the soil should be prepared by removing weed and debris. The seeds should then be sprinkled on top of the soil and pressed down gently. Water the soil until it becomes moist and place a plastic bag over the top to create a humid environment. Remove the bag once the seeds have sprouted.
The seedlings should be thinned to about 6 inches apart once they are 2 inches tall to encourage healthy growth. It takes about 25-35 days for the seeds to germinate, and the plants will flower in about 3-4 months.
Cuttings Propagation
Geranium scabrum L. can also be propagated through stem cuttings. Cuttings should be about 4 inches long, and leaves should be removed from the lower half-inch to allow for easy rooting. The cuttings should then be dipped into rooting hormone powder and placed into pre-moistened soilless media such as perlite or peat moss.
After planting the cuttings, cover them with a plastic bag and place them in a bright area with indirect light. Check the plants regularly and add water to ensure that the soil stays damp. Once the cuttings develop new growth, it means they have rooted successfully, and the plastic bag should then be removed.
Division Propagation
Division is another way to propagate Geranium scabrum L. and is commonly preferred by gardeners. This method involves separating the root system of a mature plant into two or more sections. The plant should be dug up, and the roots carefully separated with a sharp tool such as a garden knife. Each section should contain shoots, leaves, and a healthy root system.
Plant each section in a suitable location that receives the right amount of sunlight, and water regularly to support healthy plant growth.
Disease and Pest Management for Geranium scabrum L.
Geranium scabrum L. is a species of geranium native to the Eastern Mediterranean region, which is now naturalized in many parts of the world due to its attractive flowers and foliage. However, like any other plant, Geranium scabrum L. is susceptible to various pests and diseases that can affect its growth and vigor. Here are some common diseases and pests that might affect the plant and ways to manage them.
Common Diseases
Bacterial Blight: Bacterial blight is a common disease that can affect Geranium scabrum L. It is characterized by wilting and wilting of young leaves. The infected leaves turn yellowish-green and wither away. The disease spreads through splashing water and can cause severe damage if not controlled in time. To manage bacterial blight, remove infected leaves and stems, ensure proper sanitation, and avoid overhead watering.
Pythium Root Rot: Pythium root Rot is a fungal disease that affects the roots of Geranium scabrum L. The infection leads to darkening, mushy texture, and rotting of the roots, and the plant may eventually wilt and die. To manage this disease, ensure proper drainage, avoid waterlogging, and use a soilless potting mix with perlite or vermiculite to improve aeration. Fungicides may also be used in severe cases.
Common Pests
Aphids: Aphids are tiny insects that suck the sap from the leaves and stems of Geranium scabrum L. Large infestations can cause severe damage to the plant, stunting its growth and causing deformities. To manage aphids, wash them off with a stream of water, use insecticidal soaps or neem oil, and introduce natural predators such as ladybugs and lacewings.
Spider Mites: Spider mites are tiny pests that suck the sap from the leaves of Geranium scabrum L. They leave behind mottled leaves and fine webs, causing the leaves to curl and wilt. To manage spider mites, increase humidity around the plant, prune affected leaves, and apply insecticidal soap or neem oil. Natural predators like predatory mites and ladybugs can also be used.
By following these disease and pest management practices, you can help keep your Geranium scabrum L. healthy and thriving. However, if the problem persists or is severe, seek help from a professional gardener or plant pathologist.
