Serissa japonica

Serissa japonica is a small shrub that is widely used in gardens and as a bonsai due to its beautiful white flowers and glossy green leaves.

Growth Characteristics:
- Growing Environment: It thrives in warm, humid environments and requires plenty of sunlight. While it can grow in partial shade, flowering may be reduced if sunlight is insufficient.
- Soil: It prefers well-drained, fertile soil. Soil with a pH of slightly acidic to neutral is suitable.
- Growth Rate: It grows rapidly in suitable conditions and primarily forms small, dense shrubs with a radius of 15 to 45 cm.

Propagation Methods:
- Cuttings: Cutting branches in spring or summer is an effective method. Cut a branch 7 to 10 cm in length, remove the lower part of the leaves, and plant it in suitable soil.
- Seed Propagation: It can also be propagated using seeds collected later, but this takes longer than cuttings. Cultivation Method:
- Watering: Keep the soil slightly moist at all times, but avoid excessive watering. In particular, plant in a well-drained location to prevent the roots from becoming waterlogged.
- Fertilizer: It is recommended to apply liquid fertilizer monthly during the growing season. Reduce fertilizer supply during the winter.
- Pruning: Prune as needed to maintain the plant's shape and promote new growth.

Use in the Garden:
- Suitable for shaded garden edges, along walkways, and in small flowerbeds. It can also be used as a bonsai for indoor enjoyment.

Major Pests and Control Methods:
- Major Diseases: Fungal diseases such as powdery mildew may occur; these can be prevented through proper ventilation and periodic pest control.
- Major Pests: Aphids and scale insects frequently occur; to prevent this, inspect the leaves regularly and use appropriate insecticides if necessary. - Natural Control: You can attempt early control using homemade insecticides made with soap or vinegar, enabling environmentally friendly pest management.

By following these management methods, the White-flowered Flower will grow beautifully and healthily, adding beauty to your garden or indoor space.
