What is a common symptom of leaf scorch?

A common symptom of leaf scorch is characterized by the scalding and scorching of leaves. This condition often arises due to the plant's inability to take up enough water, which is typically caused by environmental stressors such as drought, excess heat, or soil compaction. When a plant experiences these stresses, it may exhibit symptoms where the leaf margins turn brown, giving a scorched appearance. This is a clear indication that the plant is suffering from a lack of moisture or extreme heat, leading to tissue damage.

In contrast, the other symptoms mentioned, such as wilting and drooping of branches or the appearance of brown spots with yellow halos, are associated with different plant stresses or diseases, which do not specifically indicate leaf scorch. Stunted shoot growth relates to overall health issues within the plant that may stem from various factors, including nutrient deficiencies or root problems, but do not directly define the condition known as leaf scorch. Hence, scalding and scorching of leaves directly corresponds to the known symptoms of leaf scorch.
