The answer to 'irrigation system schedule' is that the optimal irrigation schedule for your lawn and garden depends on several factors, including your local climate, soil type, plant types, and water availability. As a general guideline, most homeowners should water their landscapes 1-2 times per week, applying about 1 inch of water each time. This helps encourage deep root growth and maintains soil moisture without overwatering.
The best time to water is typically in the early morning or late evening when evaporation rates are lower. Avoid watering during the hottest parts of the day, as much of the water will be lost to evaporation. Additionally, it's important to adjust your irrigation schedule seasonally to account for changes in weather and plant water needs. During hot, dry periods, you may need to water more frequently, while you can reduce watering during cooler, wetter seasons.
