An irrigation controller that is capable of making daily adjustment of irrigation duration based upon historical, environmental, and or received information. The irrigation controller can automatically skip days and make changes to account for daily and seasonal environmental changes. Such automatic determination is advantageous to minimize the need of the operator intervention to make seasonal change as well as providing irrigation savings, and ensures deep irrigation. The simplified user interface and control allows for a change made at any time of the year to effect the remainder of the year to provide the best balance of minimal or no user interface, irrigation conservation.

[ What is claimed is:] [1.]1. A method of operating an irrigation controller comprising:providing the controller with a preliminary irrigation schedule having a run time;determining a deep irrigation threshold amount for an irrigation zone;determining an expected irrigation amount for a given period for the irrigation zone;accumulating the expected irrigation amount into an accumulation irrigation amount for the irrigation zone; andwhen the accumulation irrigation amount is greater than or equal to the deep irrigation threshold amount, automatically modifying the preliminary irrigation schedule to water the irrigation zone by the accumulation irrigation amount.
