Protecting ornamental plants means keeping your decorative flowers and shrubs healthy by preventing diseases and pest attacks. Think of it like guarding your beautiful garden against enemies that can destroy its appearance. Common pests include spider mites, mealybugs, and scale insects that suck plant juices, while diseases like powdery mildew create ugly white coatings on leaves.
In Nigeria, the bougainvillea plant commonly suffers from aphid infestations that curl its leaves. To protect your ornamental plants, you should inspect them regularly, remove infected parts immediately, and use appropriate pesticides when necessary. You can also apply organic methods like neem oil sprays or maintaining proper spacing for good air circulation.
Good sanitation practices, such as removing dead leaves and sterilising pruning tools, prevent disease spread. Watering at the base rather than on leaves also reduces fungal problems.
