A plant watering system is a method through which gardeners can water multiple plants at once. One of the most efficient systems for watering plants is drip irrigation. Drip irrigation conserves water by moving a low flow of water through pipes or hoses and distributing it onto the plants at the root zone to minimize evaporation. A drip irrigation system utilizes 90 percent of the water that travels through the pipes, according to Colorado State University. By contrast, sprinkler systems only use between 50 to 70 percent of the water present.
Connect a backflow preventer to your faucet.
Attach a timer to the backflow preventer. A timer will help you water your plants without requiring your presence.
Add a pressure regulating valve to the end of your timer.
Connect a garden hose to your pressure regulating valve. A garden hose will carry the water between your faucet and your drip irrigation system without losing the water.
Attach a soaker hose to the garden hose. Soaker hoses are hoses made of permeable material that sweat water onto plants or into soil that they are placed around.
Position soaker hoses around the root system of your plants. Keep the soaker hose on level ground for even water distribution. For rows of vegetables, stretch the soaker hose along the row. For flower beds, wind the hose around the drip line of each plant in the bed. Connect multiple hoses together with hose connectors. Connect multiple hoses to one water source with hose splitters. Space the hose distances 18 inches apart in sandy soil or 24 inches apart in clay and loam soil.
Cut plastic mulch to fit over the flower or garden bed. Attach the mulch to the ground with landscaping pins.
