What is a common symptom of low soil moisture in plants?

Wilt and scorch on leaves is a common symptom of low soil moisture in plants. When soil moisture levels are insufficient, plants are unable to absorb the water they need for physiological functions, including maintaining turgor pressure, which is crucial for supporting leaf structure. As a result, the leaves may start to droop, or wilt, due to the loss of water. Additionally, the leaf edges may become dry and scorched, indicating stress caused by the lack of moisture. This symptom is a clear visual cue that can help growers identify and address moisture-related issues in their crops.

While foliage discoloration can occur in various stress conditions, it might not specifically indicate low soil moisture alone. Enhanced growth typically happens when plants receive adequate moisture and nutrients, while rapid leaf drop can be a sign of various factors, including stress or disease, not directly linked to just low soil moisture. Thus, wilt and scorch are the most characteristic signs of insufficient water availability in the soil.
