Drought, or periods of water shortage, impact plants in a variety of ways. Drought affects how much water is available for plant use. If plants cannot tolerate lack of water various symptoms will appear.
Initially, growth stops and foliage wilts as plants become stressed. Unless supplemental irrigation is provided, plants may eventually die. When this happens will differ based on the plant's ability to withstand drought. Observe plants for signs of drought stress.
Water conserving features of plants such as small leaf area, lighter colored leaves and deep roots help drought adapted plants to survive long periods without water.
