Root Quencher™ is an underground watering device that delivers water to the roots of your plants. This approach eliminates evaporation from surface watering, reducing water waste by up to 50 percent. It can connect to existing sprinkler systems or a hose for easy watering. Root Quencher has a long lifespan and is now made with recycled ABS plastic. Sold by Rachio, ships separately from Root Quencher.
