What Are Helpful Tips For Doing Tree Pruning?

Tree pruning seems simple until you are standing under a gum tree with a saw in your hand, wondering which branch should go and which one should stay. I have seen plenty of Perth trees made worse by good intentions. A few cuts in the wrong spot can leave torn bark, weak regrowth, sunburnt limbs, or a canopy that looks tidy for five minutes and then struggles for years.

In a backyard, street verge, strata complex, or commercial site, pruning should always have a purpose. Maybe you need clearance from the roof. Maybe dead wood is sitting over the driveway. Maybe a young tree is forming a weak fork that will cause problems later. Whatever the reason, the best results come from slow thinking before sharp tools.

Here are practical tree pruning tips from the sort of work we see across Perth every week.

Start With a Clear Reason for Pruning

Before cutting anything, stand back and look at the whole tree. Not just the branch annoying you. The whole tree.

Ask What Problem You Are Solving

A good prune should fix a real issue. It should not be done just because the tree “looks a bit big”. Trees need their canopy to feed themselves, shade their own limbs, and cope with Perth’s heat.

Common reasons for pruning include:

• Removing dead, dying, diseased, or damaged branches
• Creating clearance from roofs, fences, gutters, paths, and driveways
• Reducing weight on long limbs
• Improving the shape of young trees
• Managing branches after storm damage
• Helping fruit trees stay productive and reachable

If there is no clear reason for the cut, leave the branch alone. That is often the best pruning decision you can make.

Think About the Tree’s Future Shape

A branch that looks small today can become a real headache later. I have seen young trees in new Perth estates with two main stems growing side by side. They look harmless early on. Ten years later, after a few winters of strong wind, that fork can split open like a busted zip.

Good pruning looks ahead. It does not just tidy up what you can see today.

Choose the Right Time to Prune

Timing matters, but it is not the same for every tree or every job. Perth has hot dry summers, sandy soils, strong coastal winds, and winter storms. Those local conditions affect how trees respond after pruning.

Avoid Heavy Pruning During Heat Stress

If a tree is already struggling after a run of hot weather, do not take a big chunk of canopy off unless there is a safety issue. Leaves are the tree’s food factory. Remove too many and the tree can run out of puff.

Planned pruning is often better in milder weather. The tree is under less stress, and the crew can see the structure clearly.

Pruning reason	Best approach	Why it matters
Dead wood over a driveway	Remove once safe	Dead limbs can fall without warning
Light shaping	Do in mild conditions	Less stress on the tree
Young tree training	Start early	Small cuts prevent bigger faults later
Storm-damaged limbs	Act quickly	Prevents further tearing or breakage
Heavy canopy reduction	Get arborist advice	Too much removal can weaken the tree

Deal With Dangerous Branches Straight Away

There is ideal timing, and then there is a cracked branch hanging over the patio. Safety wins.

If a limb is broken, split, hanging, resting on another branch, or close to power lines, do not wait for the perfect season. Get it assessed. The first decent winter blow can turn a small hazard into a roof repair bill.

Use Sharp, Clean, Suitable Tools

Bad tools make bad cuts. A blunt saw or crushed cut can leave rough wounds that take longer to seal.

Match the Tool to the Job

Small, low branches can often be handled with basic pruning tools. Large, high, or heavy limbs need proper equipment and trained people.

Tool	Suitable for	Avoid using it for
Secateurs	Small shoots and thin stems	Thick branches
Loppers	Small branches within reach	Heavy limbs
Pruning saw	Medium branches from the ground	Climbing work
Pole saw	Light overhead pruning	Large branches
Chainsaw	Trained operators	Ladder work

A simple rule: if you need to climb or use a ladder, it is probably not a DIY pruning job.

Clean Tools Between Diseased Trees

Disease can travel on dirty blades. If you cut diseased wood, clean your tools before moving to another tree. It only takes a moment.

A wipe with disinfectant or methylated spirits can help reduce the risk. It is one of those small jobs that prevents a bigger problem later.

Learn Where to Make the Cut

The right pruning cut is not flush against the trunk, and it is not halfway along a branch leaving a long stub. It should be made just outside the branch collar.

Find the Branch Collar

The branch collar is the slightly swollen area where a branch joins the trunk or a larger limb. That collar helps the tree seal off the wound.

Cutting into it damages the tree’s natural defence system. Leaving too much beyond it creates a stub that can die back and rot.

A good cut is close enough to remove the branch cleanly, but not so close that it cuts into the trunk.

Avoid Flush Cuts and Long Stubs

Flush cuts may look neat at first, but they can open the trunk to decay. Long stubs are no better. They often die, crack, and become entry points for pests and rot.

I have seen old pruning stubs sitting in mature trees like rotten pegs. They looked harmless from the ground, but up close they were soft, split, and doing the tree no favours.

Use the Three-Cut Method for Larger Branches

Large branches can tear bark as they fall. That tear can run down the trunk and create a much bigger wound than the original cut.

How the Three-Cut Method Works

Use this method only for branches you can handle safely from the ground.

1. Make a small undercut on the branch, away from the trunk.
2. Make a second cut further out from the trunk so the branch drops.
3. Make the final clean cut just outside the branch collar.

This stops the falling branch from ripping bark away from the trunk.

Know When Not to Attempt It

If the branch is heavy, high, near power lines, above a roof, or under tension, stop. That is not a backyard job.

Branches rarely fall exactly where you hope. They twist, swing, split, and bounce. That is why arborists use ropes, rigging, elevated work platforms, and proper site controls for risky work.

Do Not Remove Too Much Canopy

Over-pruning is one of the most common mistakes we see. Someone wants more light, a lower tree, or less mess, so they take too much off in one go.

The tree then pushes out weak regrowth, gets sunburnt, or starts to decline.

Leaves Feed the Tree

Leaves are not decoration. They produce the energy the tree needs to grow, seal wounds, and fight stress.

In Perth, where many trees already deal with heat, dry soil, and reflected heat from paving, heavy canopy loss can hit hard.

Avoid Lion-Tailing

Lion-tailing is when all the inner foliage is stripped out and leaves are left only at the branch ends. The tree ends up looking like a feather duster.

It also shifts weight to the tips of branches. In strong wind, that can increase the chance of limb failure.

Never Top a Tree

Topping means cutting major limbs back to stubs to reduce height. It is a shortcut, and it is a bad one.

Topped trees often respond with fast, weak shoots. Those shoots can grow back thicker and more dangerous than what was removed. It is a classic case of kicking the can down the road.

If a tree is too large for its space, get proper advice. Sometimes reduction pruning can help. Sometimes the wrong tree is in the wrong spot.

Prune Young Trees Before Problems Get Expensive

Young trees are easier to shape than mature trees. A small cut early can save a large cut later.

Train One Strong Structure

For many young trees, the aim is to encourage a strong main stem and well-spaced branches. You do not want tight forks, crossing limbs, or competing leaders fighting for the same space.

Look for:

• Two upright stems growing close together
• Branches rubbing against each other
• Weak forks with included bark
• Low branches that may need staged removal
• Fast-growing shoots heading into fences or roofs

A young tree with good structure is easier to manage, safer as it matures, and usually better looking.

Do Not Strip Young Trees Too Hard

Young trees still need leaves to build strength. Removing every lower branch too early can slow trunk development and expose bark to sun.

Sometimes lower temporary branches are left for a while, then removed gradually. It is not about making the tree look perfect on day one. It is about helping it grow properly.

Mature Trees Need a Lighter Hand

Mature trees do not need constant reshaping. In most cases, pruning should be limited and purposeful.

Focus on Safety and Health

For mature trees, pruning often involves:

• Removing dead wood
• Reducing end weight on long limbs
• Clearing roofs, gutters, and paths
• Removing damaged or rubbing branches
• Improving canopy balance

Large cuts on old trees should be avoided unless they are needed. Older trees can struggle to seal large wounds, especially if they are already under stress.

Look for Signs of Structural Risk

Before pruning a mature tree, check for warning signs. You may see cracks, cavities, fungal growth, sudden lean, dead sections, or soil lifting near the base.

If you notice these signs, do not just cut a few branches and hope for the best. The tree needs an assessment.

Perth Tree Pruning Problems We See Often

Local conditions matter. A pruning job in Perth is not the same as one in a cooler, wetter climate.

Branches Over Roofs and Gutters

Branches rubbing on roof tiles can cause damage, fill gutters, and give pests an easy path. Around solar panels, they can also block light and drop leaf litter.

The goal is clean clearance, not hacking one side of the tree flat. Prune back to suitable growth points so the tree keeps a balanced shape.

Palms Dropping Fronds Near Pools

Palms are common across Perth, especially near pools, driveways, and rental properties. Dead fronds and seed pods can make a real mess.

Palm cleaning should remove dead or risky material without overdoing it. A palm should not be shaved until it looks like a pencil with a tuft on top.

Fence-Line Branches on Tight Blocks

Older Perth suburbs often have trees growing hard against fences, sheds, patios, and retic lines. Fence-line pruning needs care because cutting too much from one side can unbalance the tree.

This is where a measured approach matters. You want clearance, not a lopsided tree that catches the next storm.

When DIY Pruning Is Fine and When to Call an Arborist

Some pruning is fine for a homeowner. Some is not worth the risk.

DIY Can Be Fine for Small, Low Branches

You may be able to prune a branch yourself if:

• You can reach it safely from the ground
• The branch is small and light
• It is not near power lines
• It will not fall onto a roof, fence, car, or person
• You know where the branch collar is
• Your tools are sharp and clean

Keep it simple. If the job feels awkward, there is probably a reason.

Call an Arborist for Height, Weight, Wires, or Doubt

Call a qualified arborist if the branch is large, high, cracked, near power lines, over a structure, or part of a tree with signs of decay.

Also call if you are not sure whether the tree should be pruned or removed. A good arborist will tell you plainly. If pruning will solve it, pruning should be considered. If removal is the safest call, you should understand why before work begins.

Good tree pruning is part skill, part patience. The aim is not to make the tree smaller at any cost. The aim is to improve safety, clearance, structure, and health without creating new problems.

In Perth, trees already deal with heat, wind, sandy soils, tight blocks, and winter storms. They do not need random chopping on top of that.

Stand back. Look at the whole tree. Decide what actually needs to be removed. Use clean, sharp tools. Protect the branch collar. Do not strip the canopy. And if the job involves height, heavy limbs, wires, decay, or doubt, get a qualified arborist involved.

Better to sort it properly now than deal with it after a branch lands on the shed.
