The answer to 'when to irrigation system' is that the best time to install an irrigation system is in the spring or fall when the weather is moderate. This allows the system to be properly installed and tested before the peak watering season. Irrigation systems should be installed by a professional landscaper or irrigation technician to ensure proper design, installation, and ongoing maintenance.
Homeowners should consider installing an irrigation system if they have a large lawn, garden, or landscaping that requires consistent watering. An irrigation system can save time and water compared to manual watering, and can be programmed to water at the optimal times of day for plant health.
