Disease Management
To manage powdery mildew and root rot, it is essential to ensure good air circulation around the plant. This can be achieved by spacing it apart from other plants, pruning any overgrown foliage, and avoiding overhead watering, instead opting for watering at the base. Additionally, removing any infected leaves, flowers, or stems can help to create a healthier environment for the plant.
Fungicides can be used against powdery mildew, while root rot is managed by ensuring proper drainage in the soil and avoiding over-watering.
Regular maintenance of the plant, including timely pruning, fertilizing, and watering, will also help to prevent diseases and pest infestations.
