Some embodiments provide methods, systems and computer readable mediums storing programs, instructions and/or coding for use in setting up and/or controlling irrigation. A method for use in controlling an irrigation system (120, 220) is provided according to some embodiments that receives a first current moisture loss value (1222), determines a first net moisture loss value since a last irrigation start day (1230, 1236, 1360) utilizing the first current moisture loss value, retrieves a threshold moisture loss value (1230, 1236, 1362) associated with one or more watering programs controlled according to one of a plurality of selectable irrigation control levels (342, 346, 352) that correspond to different ways of associating threshold moisture loss values to watering programs, and defining a current day as an irrigation start day (1232, 1240, 1364) for the one or more watering programs associated with the first irrigation control level when the first net moisture loss value has a predetermined relationship with respect to the threshold moisture loss value.
