Q.trim 30 m gum tree

Anonymous added on December 28, 2014 | Answered

I need to trim a 30 m+ gum tree by 1/3, as it is too close to the house and spreading over the roof. Your article says now is the time to trim. What angle and what do I need to dress the cut to stop disease?

The angle is not so important, but try to leave at least a 1/4-1/2 inch stub when pruning to a junction (such as a fork where 2 branches meet or where a branch meets the trunk). You don't need to seal the wounds (it can actually harm the tree if you do), but some people like to paint the cuts with a fungicide to help prevent disease.
