When they detect an extended dry period, they divert their metabolisms, producing sugars and certain stress-associated proteins and other materials in their tissues. Avoid using sugar water on plants that are growing properly. Food security and fortunes depend on rain, and nowhere more so than in Africa, where 96% of farmland depends on rain instead of the irrigation common in more-developed places.
