The K-Rain® pressure compensating bubblers are ideal for tree and large shrub watering.  Pressure compensation ensures consistent flow rates over lower pressure ranges.

Bubblers are small irrigation heads designed to bubble over and flood the ground surface around the tree or shrub. The water sinks down into the tree's or shrubs root ball (string of roots, including dirt and soil, at the base of the tree), helping to establish a deep root system.  Eliminates excess runoff or waste.
