Below is information regarding the growth characteristics, propagation methods, cultivation methods, garden uses, and major pests and diseases, as well as control methods for Concha.

Growth Characteristics
 - Environmental Requirements: It thrives in sunny locations and prefers well-drained soil. While not highly sensitive to soil acidity, it prefers a slightly acidic to neutral pH (6.0–7.0).

 - Growth Rate and Size: It grows rapidly; upon maturity, it reaches a height of approximately 1.5–3 meters and a width of 2–3 meters.

Propagation Methods

Cultivation Method
- Planting: When planting, maintain appropriate spacing to ensure sufficient space.
- Fertilization: Since the plant has low fertilizer requirements, it does not need to be fertilized too frequently. It is recommended to use slow-release fertilizers in late winter or early spring.

Uses in the Garden

Important Pests and Control Methods
- Diseases: Root rot (Phytophthora) may occur due to excessive moisture. This can be prevented by avoiding overwatering and improving drainage.
- Pests: Damage from aphids, such as the Magnolia aphid, may occur, but this is not a major issue. These can be removed by spraying with soapy water or by using natural predators. Ceanothus 'Concha' is relatively easy to care for and is a widely loved plant in gardens due to its beautiful flowers.
