A convenient, easy-to-use, 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 (mandated and voluntary watering restrictions), and property-specific data (such as type of 
plant, zone number, emitter type, and 
plant environment), with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG 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.
