Understanding plant growth stages is crucial for predicting pest and disease developments because certain pests and pathogens are more likely to target plants at specific stages of growth. For instance, seedlings might be vulnerable to different threats than mature plants. By recognizing these stages, arborists and gardeners can implement timely management practices such as applying insecticides or fungicides when the plants are most susceptible. This proactive approach helps mitigate potential damage and promotes healthier plant growth, making it an essential aspect of effective forestry and horticulture practices.
