Over the past few weeks we have been conducting formative pruning and general maintenance of juvenile street trees in Doreen. This Eucalyptus scoparia was marked for removal due to excessive rootball movement, it exhibited typical signs of a tree grown in a hard walled pot with a girdling root system. This type of root defect has long term implications on tree health and structural stability. In this case root girdling could have been prevented by using an air root pruning pot (Rocket Pot-bottom right image).
