A garden-watering tube is a HOSE, which is a flexible tube made of rubber or plastic that is used to transport water from one place to another. It is commonly used in gardens to provide water to plants and flowers. The HOSE is connected to a spigot or faucet, and the water is then released through the tube to the desired area. Hoses come in various lengths and diameters, and can be used for a variety of purposes, such as cleaning, irrigation, and even firefighting.
