The best way to manage leaf spot is to ensure adequate air circulation by spacing out your plants properly. You can also apply fungicides to prevent the spread of the disease.
Pests
Spider Mites

The first step to managing spider mites is to regularly inspect your plants and wash them thoroughly with water. You can also apply an insecticide that contains neem oil to kill the pests.
Mealybugs
Mealybugs usually attack plants that are under stress or have poor growing conditions. They appear as white, cotton-like cocoons that are easy to spot. You can remove them by wiping affected leaves with a cotton ball soaked in alcohol. Alternatively, you can spray insecticides that contain soap or pyrethrin to get rid of the pests.
By following the above tips, you can keep your Plectranthus pseudomarrubioides plant healthy and free from diseases and pests. Always remember to monitor your plant's growth and provide the necessary care to maintain its health.
