The answer to 'irrigation installation schedule' is that the ideal time to install a new irrigation system or make major renovations is typically in the spring or fall. This allows the system to be fully functional and ready for the peak watering seasons of summer or winter, depending on your climate.
Most irrigation experts recommend scheduling the installation 4-6 weeks before you plan to begin heavy watering. This gives the system time to be installed, tested, and adjusted as needed before you rely on it. The exact timeline can vary based on the size and complexity of your landscape, but planning ahead is key to ensuring a smooth installation process.
