In addition to beautifying the scenery, garden plants bring other benefits. These benefits include controlling soil erosion by helping to stabilize the soil with the root system. Unfortunately, in some areas, water is scarce, so watering plants can be difficult. Fortunately, automatic garden sprinklers can solve this problem.
Automatic garden sprinklers come in different varieties. Basic systems can consist of garden hoses connected to a control box that is installed on the water spigot. These hoses might be soaker hoses, with small holes for trickle irrigation, or standard hoses, with sprinklers attached to the ends. In more advanced systems, hoses are buried underground, and sprinkler heads dispense water. The sprinkler heads may automatically retract and extend, or they may always be above ground.
Some automatic sprinklers have advanced technological features. One type of advanced technology adjusts the water application depending on the weather report that is transmitted to the sprinkler controller. This information may be transmitted via phone, Internet or radio signal. If the weather report indicates rain, the sprinkler system does not turn on until the weather report indicates a period of dry weather. Another type of technology senses rain to prevent over-watering by delaying the watering time or skipping a watering session altogether.
Plants have different watering needs depending on the season. The automatic garden sprinkler should be set to water less in cool seasons like spring and fall and water more in the summer. In addition, automatic sprinkler systems should water at night, to avoid losing water to evaporation. Automatic sprinklers can be set to turn on and off multiple times to prevent excess runoff and wasted water in sloped areas or areas with hard soils.
Care should be taken when designing automatic garden sprinkler systems. Sprinkler heads should be set so lawns are watered separately from garden beds, due to different needs. Sprinkler heads should not put water onto paved surfaces, to avoid waste from runoff. Avoid leaving too much space between heads and creating dry spots. Sprinkler heads should ideally overlap to provide adequate water coverage. Water pressure should be adjusted to avoid fine sprays that may blow in the wind.
Automatic garden sprinkler systems have many benefits, like reducing the amount of water needed to properly maintain the garden. By watering at cooler times and only watering at the optimum frequency, water consumption can be reduced by up to 40 percent. This is accomplished by reducing the amount of water runoff and reducing the amount of evaporated water. Reducing water consumption will save the homeowner money in the long run.
