Provide adequate humidity, especially for indoor plants, by misting regularly or using a humidifier. Protect from strong winds and direct sunlight, which can scorch the foliage. In colder climates, mulch around the base of the plant in fall to protect the roots from freezing temperatures. Regularly inspect for pests and diseases, such as aphids and powdery mildew, and treat accordingly. Ensure good air circulation to prevent fungal problems. Repot container-grown plants every 2-3 years in spring.
