What does damaged foliage typically look like?

Damaged foliage that appears stippled and discolored typically indicates the presence of certain pests or diseases that affect plant health. This appearance often results from feeding by insects such as spider mites or aphids, which can create small puncture wounds in the leaves, leading to tissue damage. As a result, the leaves may exhibit mottled patterns or faded colors, which can significantly diminish the aesthetic quality of the plant and its ability to photosynthesize effectively.

In contrast, other appearances of damaged foliage indicate different issues. Leaves that are brown and wilted often signify environmental stress such as drought or improper watering practices. Soft and mushy leaves suggest rotting or fungal infection, usually due to overwatering or poor drainage. Curled and hardened leaves might indicate stress responses to environmental factors or plant diseases, but do not typically align with the stippling pattern associated with insect damage. Understanding these distinctions is essential for diagnosing plant health issues effectively.
