A garden hose is a flexible tube typically made of rubber, PVC (polyvinyl chloride), or a combination of materials, designed for outdoor use in watering plants, lawns, and gardens. It connects to a water source, such as a faucet or spigot, and allows users to convey water to specific areas with ease. Garden hoses come in various lengths, diameters, and materials, offering options for different watering needs and preferences.
