When to Buy

The best time to buy an irrigation controller is typically before the peak watering season begins, such as late winter or early spring. This allows you ample time for installation and programming before your lawn and garden demand consistent watering. Purchasing outside of peak season may also sometimes offer seasonal discounts.
