full description

The Mona Aria Relief Grande offers all the irrigation power of the standard Grande system – but with the added benefit of integrated air venting, ensuring improved oxygen exchange around the tree's rootball. This system is engineered for large and semi-mature trees where effective watering and root aeration are essential for healthy establishment in urban and landscape environments.

Using 60mm perforated piping combined with an air-venting inlet and optional dual fill access (on 8m Double Inlet model), the Aria Relief Grande is a best-in-class solution for heavy-duty rootball hydration and long-term tree health.
