Don’s Expert Answers: Large Lemon Scented Gum in large backyard. Planted when neighbours all had large backyards, but now houses have been built close to the tree. Is this dangerous? I recently had to cut down and grind the stumps of two other Lemon scented gums as they were very close to the fence line and the new house built in the neighbour’s backyard. The remaining gum is a few metres from where the trees were. Will the dying root systems from the other trees make the remaining tree unstable? Last question are these trees a fire hazard because of the eucalyptus oil?

Answer:
Hi Julie, The Lemon Scented Gum tree (Corymbia citriodora) is prone to dropping large branches. It is a magnificent tree on larger properties, but it should be planted at least 15m away from houses and sheds. It is not a fire hazard in your situation, nor are the dead roots a problem. Do not camp under gum trees either. Don
