Weed Potential 
As a weed Sugar Gum is invasive appears in habitats including woodlands or grasslands and disturbed or cleared land. It colonises slowly forming small stands that reducing the regeneration of native tree or shrub seedlings and understorey plants. 

It prefers an open sunny position tolerating hot dry periods and grown in most soils except wet boggy types. It is fast growing with seedlings germinating in an open sunny position and mature plants dry and harden the surrounding soil. 

Seeds are produced prolifically in autumn but the viability period is short and the seedlings don’t appear on mass. The seeds are dispersed by gravity, water and in pruned material. 

Control methods include physically digging out seedlings and small plants when the soil is moist ensuring that the roots are removed as the slender trunks snap off easily and the plant re-shoots from the base. 

Fruiting branches should be bagged and destroyed if possible. Plants can be cut and painted on the stems or drilled and injected in the trunk towards the base with a non-selective herbicide during spring-summer. Follow up applications may be requires as the tree may re-shoots. 

Young plants or seedlings may be sprayed with a non-selective herbicide during spring while the plant is actively growing.
