This review focuses on the ability and strategies of higher plants to respond and adapt to drought stress, and the critical roles of osmolyte accumulation under drought stress conditions. The parameters assessed ranged from the percentage of seeds that germinated through morphological characters to measurements of intracellular solutes. Plants suffering from drought more easily succumb to pests and diseases. Plants absorb water through their roots and expel most of it it though their leaves though a process called transpiration. Long-term symptoms of drought include dieback of branches and death of the plant as the plants capacity to absorb water is damaged. In agricultural ecosystems, drought has a detrimental effect on crop production, affecting the growth rate and development of the economically important portions of the plant, such as fruits, grains and leaves. A lawn with longer grass suffers far less drought stress than a closely mown one. Clearly going too early means cooler or even cold weather so we have to compromise between early and too early. Some gardeners create special gardens for plants that can cope with reduced water availability. Some water is lost though the stems and flowers but most of it is lost via the leaves.
