“Plant stress” refers to conditions that impact plant growth, yield, or survival. These stressors can be abiotic (e.g., light, water, nutrients, and temperature) or biotic (e.g., pests and pathogens). Plant responses to stress vary; therefore, there is no single symptom or solution.

Wilting leaves often indicate plant stress caused by water issues, drainage problems, root rot, or a damaged root system. Addressing this involves adjusting the watering (not under- or overwatering) and ensuring proper drainage.
