The answer to 'how often to sprinkler system' is that most homeowners should run their sprinkler systems 2-3 times per week during the growing season. This helps ensure your lawn and landscaping receive the optimal amount of water to stay healthy and thrive. The exact frequency will depend on factors like your local climate, soil type, and the specific plants in your yard.
As a general guideline, aim to provide your lawn with about 1-2 inches of water per week, either through rainfall or irrigation. During hot, dry periods, you may need to run your sprinklers more frequently to keep up with increased water demand. It's also important to adjust your watering schedule with the seasons, reducing frequency in the fall and winter when growth slows.
