You can't teach an old tree new tricks. But a young one? That's a different story — and it's the whole point of pruning young trees in the first place.
Start pruning a young tree at the time of planting. Remove dead, damaged, or crossing branches right away. Then wait. For the first two or three years, let the tree put its energy into root establishment and canopy growth. After that, you start shaping.
Quick answer: Pruning young trees is about building structure before problems become permanent. Remove dead and crossing branches early. Select one central leader and train scaffold limbs outward. Do it lightly — no more than 15% of the canopy per season. The work you put in during the first five years determines how the tree handles the next fifty.
Why pruning young trees matters more than you think
A neglected young tree doesn't just look awkward. It develops structural problems that become expensive to fix — or impossible to fix — once the trunk thickens.
Two competing leaders, for example. Left unmanaged for five years, each one grows a trunk-size stem. By then, you're dealing with an included bark union — a pinched seam between two stems that's essentially a fault line. That's where trees fail in windstorms. Correction at that stage costs far more than a simple early cut would have.
I had a homeowner come to us with a maple he'd attempted to prune himself a few years before. He'd cut it back hard, left stubs, and the tree responded with four competing leaders where there had been one. By the time he called, every stem was a potential failure point. We crown-reduced it properly for $800. If he'd called us in the early years, a proper structural prune would have been $350.
The ISA (International Society of Arboriculture) is clear on this: structural pruning during a tree's first 25 years reduces long-term maintenance costs and failure risk. It's an investment, not a maintenance task.
The first two years: what to do at planting
On the day of planting — or within the first season — remove anything that's clearly wrong. Dead branches. Broken branches. Any branch rubbing against another.
That's it. Don't do more.
The tree just went through root disturbance. It needs canopy to photosynthesise and drive root growth. The instinct to "clean it up" by removing half the branches is usually the wrong call. Leave the lower branches on — they help the trunk build taper and strength. Iowa State University Extension recommends keeping lower branches as long as possible in the early years for exactly this reason.
After two to three years — once the tree has established — you start structural pruning. Not before.
Training for structure: leaders and scaffold limbs
Nine out of ten young trees planted in a Surrey yard need a central leader selected. That's the main upright stem — the tree's spine. Everything else is a scaffold limb growing outward from it.
If there are two competing leaders of similar size, pick the stronger one and subordinate the other. That means shortening it by a third — not removing it all at once. Removing it entirely in a single session is a stress the tree doesn't need. Shorten it one season, remove it the next.
Scaffold limbs should be spaced evenly around the trunk — think of a spiral staircase going up the tree, not a stack of branches all pointing the same direction. Limbs too close together compete for light and create crowded unions. Aim for 20–30 cm of vertical spacing between major limbs on young deciduous trees.

What to cut — and in what order
Work through this list in order. Stop once you've reached the 15% canopy limit.
1. Dead and diseased branches.Always. No limit applies — dead wood isn't live canopy.
2. Broken or damaged branches. Same rule. Remove to the nearest healthy branch junction.
3. Branches crossing or rubbing. Choose the weaker or more awkwardly angled one and remove it. Left alone, rubbing branches wound each other and create entry points for disease.
4. Competing leaders.If there are two stems fighting for dominance, subordinate or remove the weaker one. This is the most important structural cut you'll make.
5. Branches with narrow V-crotches.A V-shaped union between a limb and trunk is structurally weak. Broad U-shaped unions are the ones to keep. If a branch has formed included bark — where the union looks like it's pinching inward — it's a long-term failure risk.
Rule of thumb: if removing a branch requires hesitation, leave it for next season. Better to take less than you planned than more.
Where to make the cut
Every cut should be made just outside the branch collar. That's the slight ridge of bark where the branch meets the trunk or parent limb. The collar contains the tissue the tree uses to seal over a wound. Cut into it and healing is compromised. Cut too far from it and the stub left behind rots.
Do not leave stubs. Do not flush-cut. Cut just outside the collar at a slight downward angle so water doesn't pool on the cut surface.
Use bypass pruners for anything under 2.5 cm diameter. Loppers up to around 4 cm. A handsaw for anything larger. Anvil pruners crush tissue — avoid them for live branches. The ISA's pruning guide for tree owners covers cut placement with diagrams if you're working on your own.
How often a young tree needs pruning
For the first five years: once a year, or once every two years at minimum. Structure is still setting. Small corrections now prevent larger interventions later.
After year five, once the scaffold is established: every three to five years for maintenance. More often if the tree is in a tight spot, growing near a structure, or developing problems faster than expected.
The best time of year in BC's Lower Mainland is late fall through early spring — November to February — when the tree is dormant and branch structure is visible. That said, I reckon this matters less than people think. A dead branch is worth removing in August just as much as in January. Stop waiting for the "right" season if something clearly needs to come off.
When not to do it yourself
For small trees under 10 feet, basic dead-branch removal is genuinely manageable on your own. Sharp bypass pruners, correct cut placement, and you're fine.
Don't do it yourself if:
- The tree is over 15 feet and you need a ladder to reach the work — that's where falls happen
- The tree is near a structure, power line, or fence
- You're making structural decisions — competing leaders, large limb removal — without training in branch biomechanics
- The tree is a species that requires specific timing (cherries and other Prunus species should not be pruned in wet weather due to disease risk)
We're happy to talk someone out of hiring us if a small job is genuinely DIY-able. Give us a call or send a photo and we'll tell you honestly. The worst outcome is paying a professional for something you could have safely done yourself. The second-worst is injuring yourself on a ladder or creating structural problems that cost more to fix than prevent.
What pruning a young tree costs in Surrey, BC
Young tree pruning is among the more reasonable tree care jobs, because the scale is still manageable. I reckon most homeowners in Surrey are surprised by how affordable it is when done early.
| Tree size | Typical cost (CAD, all-in) |
|---|---|
| Under 10 ft — dead-branch removal | $150–$300 |
| 10–20 ft — structural prune | $300–$500 |
| 20–40 ft — crown thinning or reduction | $500–$800 |
| Consultation (credited toward work) | $150 |
Prices are flat and all-in — we don't add cleanup fees after the fact. For a precise number, a quick on-site assessment is the fastest route. The $150 consultation fee is credited toward the work if you proceed.
