When we nurture the ornamental plants frequently, we will start to understand even the slightest change happening to the plant. White patches or spots on the leaves is a sure sign of virus infection in the plant. It can be cured by plucking out the affected leaves. Holes in the leaves suggest insect habitation. This can be recognized as shot hole disease and is a common ailment in many plants.
If this disease is spotted, immediately move the pot outside and spray fungicide on it. Move the pot back again only after two or three days. Root rotting disease can be confirmed when the ornamental plant shows stunted growth and yellow leaves. This ailment is due to water logging in the potted mixture and can be cured by changing the potted mixture with immediate effect. The decayed roots should also be removed. These are some of the most common ailments that affect decorative plants.
