A convenient, water-saving and labor-saving FROG irrigation controller and system are provided, which determine the appropriate water budget and schedule for the property's landscaping based on evapotranspiration data for the geographic area, regulation data (any mandated and voluntary watering restrictions), and property-specific data, with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG controller provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to comply with local mandated and voluntary watering restrictions. Compliance is automatic and obligatory, meeting the water saving goals of the local water authority. Optionally presented is a web-based wizard used to determine a customized water budget/schedule that is input into the FROG controller through a data storage unit or wireless input.
