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

Are bubblers good for trees?

Drip irrigation and tree bubblers improve plant growth. The slower water flow percolates into the soil and into the plant’s root zone. This precision leads to healthy plant growth because the shrubbery, trees or landscaped areas are getting the right amount of water at the right flow.

How many tree bubblers are in a zone?

Mature trees always take two bubbler emitters, one on each side, in order to ensure an acceptable uniformity of application. The flow rate per tree is relatively high compared with other micro-irrigation techniques at about 500 litres/h.
