Less than a year after my retirement, it shed a couple of major limbs and was removed.
Key Points:
- Less than a year after my retirement, it shed a couple of major limbs and was removed.
- I had been its custodian for over 20 years and took my responsibility seriously, extending its useful life.
- It’s a shame, because there is much to appreciate and admire about the sugar gum.

Hard to kill: here's why eucalypts are survival experts
A hardy and impressive tree
- In its natural habitat in the Flinders Ranges, sugar gum can be an impressive single-trunked tree.
- Like many eucalypts, sugar gum is a hardy tree with plenty of dormant buds (epicormic buds) under its smooth yellow, grey bark.
- When the tree is damaged by fire or stressed, these buds may become active and produce lots of new shoots.
A tree that leaves a lasting impression
- Coming from the western suburbs of Melbourne, I remember lots of them in rows at the intriguing Albion Explosive Factory.
- These trees left a lasting impression.
- More broadly, though, many in the wider Australian community still see sugar gums only as risky trees that drop dangerous branches.
Lopping and topping
- These trees are capable of growth in heavy clay soils, drought tolerant and efficient water users.
- They were a tree that more or less looked after themselves in tough conditions.
- Some were regularly pruned at a lower height to encourage growth for the rapid production of firewood or fence posts.
- But when you stopped lopping and topping, the shoots grew quickly.
A haven for native animals
- Many sugar gums feature hollows and cavities, which become a haven for native fauna.
- These provide a home for a possum or two, but it is perhaps parrots that benefit most.
- At certain times of year, there is a deafening din around sugar gums as sulphur-crested cockatoos, corellas and lorikeets jostle for nesting sites.
