Appearance and Growth Habit

It features oval, glossy green leaves that can grow up to 6 cm long, providing a lush and vibrant appearance.

Pruning and Maintenance

Regular pruning is necessary to maintain the desired shape and size, especially when used as a hedge.

Pests and Diseases

California privet is not prone to pests or diseases. However, the following are able to effect privet plants. 

Pests

1. Vine Weevil: These beetles feed on the foliage, causing significant damage. Adult beetles have a brown and black coloration, while larvae live in the soil around the roots. Use insecticides and soil drenches to control infestations.

2. Spider Mites: These microscopic pests feed on leaf sap, leaving yellow spots and white webbing. Warm, dry conditions favour their proliferation. Treat with insecticides and repeat applications to prevent re-infestation.

3. Scale Insects: These small pests cause yellow spots on leaves by feeding on sap. Treat with insecticidal soaps or horticultural oils, ensuring thorough coverage and multiple applications for effectiveness.

Diseases

1. Honey Fungus: This fungal disease produces white mycelium threads and yellow mushrooms at the base of the plant. Infected plants should be removed and destroyed immediately to prevent spread.

2. Powdery Mildew: Characterized by white patches on stems and leaves, this disease can cause yellowing and wilting. Treat with fungicides and follow up with a second application to ensure complete control.

3. Rust and Leaf Spot: These fungal diseases cause reddish-orange (rust) or yellow/brown (leaf spot) discolorations on leaves. Treat with fungicides, ensuring thorough coverage of affected areas.

Preventive Measures

• Sanitation: Keep the area around your privet hedge free from fallen leaves, twigs, and other organic debris to reduce the risk of fungal infections.
• Monitoring: Regularly inspect your plants for signs of pests and diseases, allowing for early detection and treatment.
• Proper Watering: Avoid overhead watering, which can create a humid environment conducive to fungal growth. Water at the base of the plants to keep foliage dry.
