Lopping, pruning and crown work done properly

Lopping has a bad name for a reason

Cut a healthy eucalypt back to bare stubs and it will respond. Dormant buds fire, and within two seasons there is a dense flush of new shoots attached to nothing but a decaying stub. Those shoots grow fast, weigh a lot, and are held on by a shallow attachment. The tree looks tidy for eighteen months and then becomes more dangerous than it was before, and you pay twice.

Proper pruning does the opposite. Cuts are made back to a branch collar or a suitable lateral, the tree seals the wound, and the shape holds. The Australian Standard for pruning of amenity trees, AS 4373, sets out how. Any contractor quoting your job should be able to say which operation they are proposing and why.

The four operations that cover most jobs

Crown thinning. Selective removal of inner and secondary branches to let wind through a dense crown. The standard treatment before storm season for mango, poinciana, camphor laurel and anything else that has grown into a solid ball.

Crown reduction. Shortening the outer crown back to suitable laterals to reduce height and spread. Used where a tree has outgrown its space or is leaning over a structure. Not all species take it well.

Deadwooding. Removing dead, hung-up and broken material from the crown. It is the cheapest tree work there is and it removes the most common cause of damage — a dead limb letting go in the first gust of a summer storm.

Clearance pruning. Lifting the crown off a roof, out of gutters, away from a solar array, off a boundary fence or back from a driveway sight line. Usually the reason someone picks up the phone.

Brisbane-specific timing

The severe storm season runs roughly October to March, and November is historically the worst month for damaging hail and downbursts through the city. The useful preparation window is therefore winter: May through September, when the ground is firm enough for a chipper on a lawn, growth has slowed, and crews are not triaging storm calls. Book thinning and deadwooding then and it costs less and gets done sooner.

What pruning will not fix

A prune will not repair a split union, cure root rot, stop a fig lifting a driveway, or make a structurally unsound tree safe. It will not permanently stop a camphor laurel or Chinese elm, because both regrow faster than you can afford to keep cutting. And it will not make a tree that is shading the whole yard into a small tree — reducing a large eucalypt by a third and then repeating that every two years is more expensive over a decade than removing it once and planting something the right size.

Where the tree is worth keeping but the branches over the house are the problem, pruning is exactly right. Where the species is the problem, it is not.

Protected trees still need approval to prune

This surprises people. Under Brisbane City Council's vegetation protections, significant pruning of a protected tree can require approval in the same way a removal does, and verge trees are council property whether or not the branches hang over your roof. The council rules page explains what to check. If you are not sure what your tree needs, describe it on the contact page or look at the ranges in the cost guide first.
