Angophora costata

This tree should be watered deeply and regularly (when the top couple of inches of soil has dried) to establish for the first few years and then infrequently but deeply. Usually this will be once every couple weeks to a month during dry weather.

Tree will also thrive with regular watering and is not sensitive to overwatering.

Often a tree will tap into groundwater and need less watering or none at all, once established.

A great trick for watering street trees is to drill a â…› inch hole on the bottom edge of a five gallon bucket and set the hole next to the tree and fill the bucket with water. Fill once for a 1-5 gallon plant, fill twice for a 7-15 gallon plant, three times for 25g or larger plants.
