A garden hose is a long, flexible tube used for watering plants and other outdoor activities. It typically consists of a durable outer layer made from materials such as rubber or plastic, with an inner tube that carries water through the hose when it's turned on. Gardeners use them to irrigate their gardens by attaching one end of the hose to a source of water (such as a tap or sprinkler system) and directing the flow of water towards their plants with a nozzle or sprayer at the other end. The length, width, and pressure regulation features vary depending on the specific type of garden hose.
