Leaf scorch意思

"Leaf scorch" is a term used to describe the browning or drying of the edges of leaves, typically due to environmental stress, such as excessive heat, drought, or exposure to harsh chemicals. It can affect a wide range of plants, from trees to shrubs to ornamental plants. Leaf scorch can be a symptom of various plant diseases, nutrient deficiencies, or physiological disorders. In some cases, it may be caused by root damage, which can limit the plant's ability to absorb water. The condition is more common in plants that are already stressed or in those that are planted in areas where the soil type or pH is not suitable for their growth.
