- Leaf spots: This disease is caused by fungi or bacteria and often presents as small circular or irregular brown spots on the plant leaves. Remove infected leaves and avoid overhead watering to prevent the spread of the disease.
- Rust: This fungal disease causes orange to rust-colored spots on the leaves. Remove infected plant parts and make sure to water the plant at the base to prevent water from settling on the foliage.
- Mildew: Powdery mildew can form a white, powdery coating on the leaves and stems. To prevent and manage this disease, reduce humidity and increase air circulation around the plant.
Pest Management
Geranium arabicum Forssk. subsp. arabicum is also generally resistant to pests, but some common pests that might affect the plant include:
- Aphids: Small, pear-shaped insects that suck sap from the plant, causing deformities and leaf curling. Use a strong spray of water to knock aphids off the plant or apply insecticidal soap or neem oil to the plant.
- Spider mites: Tiny, sap-sucking pests that can form webbing on the plant. To manage spider mites, increase humidity around the plant and use insecticidal soap or neem oil.
- Thrips: Slender, tiny insects that cause distorted growth and damaged flowers. Use insecticidal soap or neem oil to manage thrips.
- Whiteflies: Small, winged insects that suck sap from the plant and cause leaf yellowing. Use yellow sticky traps to monitor infestations and apply insecticidal soap or neem oil to manage whiteflies.
