Diy vs hiring a arborist what you can and cant do (2026)
Quick Answer
You can usually handle low-risk tree jobs yourself, such as light pruning of small, reachable branches, watering, mulching and basic inspection. You should not attempt work involving climbing, chainsaws aloft, branches near power lines, large limbs, unstable trees, storm damage or full tree removal. When the consequences of getting it wrong include injury, property damage or killing the tree, hire a qualified arborist.
Overview
DIY tree care makes sense when the work is simple, done from the ground, and limited to small branches you can cut cleanly with hand tools or a pole pruner used within the manufacturer’s instructions. Good DIY jobs include removing dead twigs, pruning for basic shape on young trees, mulching correctly, watering during dry periods and checking for obvious defects such as cracks, fungal growth or rubbing branches. The limits come quickly: trees are heavy, unpredictable and often hide decay, tension and weak unions. A cut in the wrong place can start decay, reduce stability or trigger poor regrowth, and a falling limb can cause serious harm. Hiring an arborist is the safer choice for tall trees, mature trees, any work that needs climbing or rigging, branch removal over roofs, roads or fences, and any tree with signs of disease, root damage or structural problems. It is also the right move if the tree may be protected or if you are unsure whether pruning is appropriate at all. The most practical way to decide is to ask two questions before you start: can this be done safely from the ground, and am I certain which cuts are beneficial to the tree? If either answer is no, get professional help.
Who this is for
Homeowners, landlords and property managers deciding whether to do basic tree maintenance themselves or call an arborist.
What you’ll need
- clean, sharp hand pruners or loppers
- pruning saw suitable for green wood
- manufacturer-approved pole pruner if needed
- gloves and eye protection
- sturdy footwear
- mulch for tree care around the base
- access to local council tree rules
- a way to photograph defects for advice or quotes
Before you start
Check whether the tree is protected by local council rules, in a conservation area, or subject to any consent requirement. Identify hazards first: overhead power lines, traffic, neighbouring property, dead hanging branches, visible cracks, cavities, fungi, heaving soil around roots or recent storm damage. Read the tool manufacturer’s safety instructions and stop if the work would require climbing, ladder use while cutting, or cutting anything you cannot control as it falls.
Step-by-step
- 1
Decide if the job is genuinely low risk
Limit DIY work to small, reachable pruning and routine care done from the ground. If the branch is high, heavy, above a target such as a roof or fence, or the tree shows signs of structural weakness, treat it as an arborist job.
Why: Most serious accidents and expensive damage happen when people underestimate weight, height and hidden defects.
- 2
Check legal and site restrictions
Confirm whether you are allowed to prune or remove the tree. Look up local council rules, and if power lines are involved do not start work yourself. If the tree is on a boundary, clarify ownership and access before cutting.
Why: Protected trees, utility clearances and boundary disputes can create legal and safety problems even when the pruning itself seems simple.
- 3
Inspect the tree before any cut
Walk around the tree and look for dead wood, split stems, cavities, fungal fruiting bodies, peeling bark, exposed roots, soil movement and branches rubbing or crossing. Note what is dead, damaged or diseased and whether the crown looks unbalanced.
Why: Inspection tells you whether the tree needs diagnosis rather than pruning. Structural defects often mean the safest option is professional assessment.
- 4
Do only basic, correct pruning
If the job is suitable for DIY, remove small dead, damaged or crossing branches with clean cuts just outside the branch collar. For heavier branches that are still within safe DIY limits, use a staged cutting method to avoid bark tearing. Do not top the tree, leave stubs or cut flush to the trunk.
Why: Correct pruning supports wound closure and reduces decay. Bad cuts can permanently weaken the tree and trigger poor regrowth.
- 5
Keep your feet on the ground
Use hand tools or a pole pruner only as intended. Do not climb the tree, do not use a chainsaw from a ladder, and do not work underneath a partly cut branch. Clear bystanders from the drop zone before each cut.
Why: Tree work becomes significantly more dangerous once balance, overhead cutting and uncontrolled falls are involved.
- 6
Finish with aftercare, not over-pruning
Water during dry periods if the species and local conditions warrant it, and apply mulch around the root zone while keeping it away from direct contact with the trunk. Monitor the tree over the following weeks and seasons for dieback, oozing, fungal growth or unexpected leaf loss.
Why: Trees recover better when root stress is reduced. Ongoing symptoms after pruning may indicate an underlying problem that pruning did not solve.
- 7
Call an arborist when the signs point beyond routine care
Get professional help for large pruning jobs, removals, storm-damaged trees, suspected disease, root issues, leaning trees, trees near utilities, or any time you are uncertain about the correct cut or safe work method.
Why: An arborist can assess structure, choose the right pruning approach, and use climbing, rigging and safety controls that are not suitable for DIY work.
Why this works
The DIY-versus-arborist decision works best when based on two factors: risk to people and property, and biological risk to the tree. Small, ground-based maintenance is manageable because the loads are lighter and the cuts are easier to make correctly. High or heavy work, defects, and utility conflicts need specialist assessment and control methods.
Common mistakes to avoid
- Using a ladder while cutting branches
- Cutting too close to the trunk or leaving long stubs
- Topping a tree to reduce height quickly
- Assuming a healthy-looking canopy means the tree is structurally sound
- Pruning near power lines instead of contacting the utility or a qualified professional
- Removing too much live growth at once
- Ignoring local protection rules or neighbour issues
Troubleshooting
Bark tears down the branch or trunk during cutting
Stop and tidy only what you can safely reach with a clean final cut outside the branch collar. For larger damage or high cuts, have an arborist assess it.
The tree looks stressed after pruning
Check watering and mulch, avoid further pruning for now, and watch for dieback or leaf loss. Seek arborist advice if symptoms continue or worsen.
You find fungal growth, cavities or fresh cracks
Do not continue pruning or removal yourself. Restrict access beneath the tree and arrange a professional inspection.
A branch is entangled, hung up or partly broken after a cut
Keep clear and do not try to pull it down. This is a professional retrieval job because stored tension can release unpredictably.

Alternatives
- Have an arborist do a one-off inspection and pruning plan, then handle only the routine aftercare yourself
- Ask for a maintenance schedule instead of major reactive pruning
- Use selective reduction by a professional rather than full removal when risk and tree health allow
Pro tips
- Photograph the tree from several angles before pruning so you can plan cuts and compare results later
- Start with the smallest necessary cuts and stop before the tree looks thinned out
- Disinfect cutting tools when moving between obviously diseased and healthy material, following the tool or product instructions
- If you are not sure whether a branch is dead, scratch a tiny area of bark on a small twig first rather than making a large cut
- When getting quotes, ask what pruning objective is proposed, such as deadwood removal, crown cleaning or risk reduction
Safety notes
- Never work within reach of overhead power lines; keep well clear and contact the utility or a qualified professional
- Do not climb trees or use a chainsaw from a ladder
- Wear eye protection, gloves and sturdy footwear
- Keep children, pets and bystanders away from the work area
- Stop immediately if the branch moves unpredictably, binds the saw or reveals internal decay
- Do not attempt storm-damaged or partially fallen trees yourself
Legal & regulatory notes
Tree pruning and removal can be controlled by local council rules, protected-tree schedules, utility clearance requirements and boundary law. The exact rules vary by location, so check your local council and electricity network guidance before starting. If the tree straddles or affects a boundary, resolve ownership and access issues before any work.
What this guide does not cover: This guide helps you decide between basic DIY tree care and hiring an arborist. It does not replace a site-specific hazard assessment, utility advice, local council consent guidance or a professional diagnosis of tree health and structure.
Cost considerations
DIY can save labour costs for simple maintenance, but mistakes can create much bigger costs through property damage, emergency call-outs, failed trees or avoidable decline. Hiring an arborist usually costs more upfront, but it is often cheaper overall for risky or technically sensitive work because it reduces the chance of injury, legal issues and repeat pruning.

Frequently asked questions
Can I prune a tree myself?+
Yes, if it is limited to small, reachable branches and routine care done safely from the ground with the right hand tools. If it involves height, heavy limbs, defects or uncertain tree health, hire an arborist.
What jobs should I never do myself?+
Do not attempt work near power lines, climbing and cutting aloft, chainsaw use from a ladder, large limb removal over targets, storm-damaged trees, hung-up branches or whole-tree removal unless you are properly trained and equipped.
Is tree topping a good DIY shortcut?+
No. Topping is widely discouraged because it creates large wounds, weak regrowth and long-term structural and maintenance problems.
How do I know if a tree is unsafe?+
Warning signs include fresh cracks, cavities, fungal growth, dead upper branches, sudden leaning, root plate movement, soil heave and major bark loss. These signs need professional assessment.
Should I paint or seal pruning cuts?+
In most cases, no. Trees generally respond better to proper pruning cuts than to wound dressings, unless a specific local disease-management recommendation says otherwise.
