Hoses and sprinkler systems can aid in the maintenance of gardens, building lawns, and other green spaces. Water flow can be controlled or diverted with the use of garden hoses, nozzles, and accessories. Sprinkler heads, lawn sprinklers, and subterranean sprinklers all give water to grass and vegetation where it's needed the most. Drip irrigation systems use a regulated dripping mechanism to irrigate plants and are used in locations where water usage is limited. Irrigation and sprinkler timers control the amount of water provided by turning sprinklers on and off at specific periods. Hose reels, racks, and carts mounted on the wall keep garden hoses organized.
