How can the scale on leaves be used to determine the health of a plant?

The scale on leaves can be used to determine the health of a plant by observing its color, texture, and overall condition. Changes in the scale, such as discoloration, wilting, or damage, can indicate issues like nutrient deficiencies, disease, or pest infestations. By monitoring the scale on leaves, gardeners and botanists can assess the plant's health and take appropriate actions to address any problems.
