Your apple tree has been doing something quietly impressive for the last fifteen years. Mostly growing sideways.
Pruning old apple trees is one of those jobs that keeps getting deferred because it looks too big to tackle from the ground. And by the time most people do tackle it, it is genuinely too big to do safely in a weekend. The good news: most neglected trees can come back. The honest news: it takes two or three seasons, and some trees are better removed than renovated.
Here is how to tell which situation you are in, and what to actually do about it.
Quick answer: Start in late winter while the tree is dormant. Remove no more than 20–25% of the canopy this season. Do not cut the central leader back to a stub — that one mistake will give you six years of watersprouts.
Why old apple trees need different care
A young apple tree tolerates fairly aggressive pruning. You are shaping it and the energy is there to recover.
An old neglected tree is a different situation. Years of growth have created crossed branches with rubbing wounds. Deadwood has built up in the canopy. The tree has put energy into vegetative growth — long, whippy water sprouts reaching for light — rather than fruit production.
The problems compound. A neglected canopy develops rubbing branches that wound each other. Dead wood creates entry points for fungal disease. Water sprouts — the fast vertical shoots that sap energy without producing fruit — start to dominate. And the canopy gets dense enough that air and light cannot get through, which is exactly when apple scab and powdery mildew take hold.
All of this is fixable. The question is how much you can responsibly fix in one season.
The best time to prune an old apple tree
Late winter, while the tree is fully dormant. In Surrey and the Lower Mainland, that typically means February through early March — after the coldest weeks, before the buds break.
Here is why it matters especially for old trees: a dormant tree responds to pruning cuts more slowly. There is less sap flow, fewer pathways for disease to enter, and the wounds have time to callus before the growing season stresses the tree. Large cuts on an old tree heal better in winter than at any other time.
Rule of thumb: the buds should be visibly swollen but not yet open. Once leaves are out, the tree is already burning energy on new growth. Large renovation cuts at that point take more out of the tree than they need to.
One note for BC specifically: a wet February is fine for pruning. The limiting factor is frost, not rain. If night temperatures drop below -5°C, hold off — fresh cuts and hard frost are a bad combination, especially on older wood.

How to assess a neglected apple tree before you start
Before cutting anything, spend twenty minutes just looking at the tree.
Check the main scaffold branches — the large limbs that form the tree's structure. Healthy scaffold branches have intact bark with no visible cracks or soft spots. If the main scaffold is solid, the tree is worth renovating.
If you see large splits at a branch union, sunken dead bark on primary limbs, or any sign of a hollow trunk — the prognosis changes. At that point you want a structural assessment before committing to renovation work.
Also check the trunk base. Any fungal fruiting bodies (mushrooms, conks) at or near the base are a red flag for root rot. A lifting root plate means the tree is already unstable. Either of those is a conversation about structural integrity, not pruning technique.
If the trunk and main scaffold look solid and the bark is healthy — the rest is addressable. Dead wood, crossed branches, water sprouts: all of that can be worked through over a couple of seasons.
Ask yourself honestly: is this tree worth saving? Not "can we save it" — can we is different from should we. A heritage apple variety on a large sunny lot with solid structure is worth the two-year investment. A scraggly crabapple in a dark corner with a split trunk probably is not.
Step-by-step: how to prune an old apple tree
Start with the three Ds: dead, diseased, and damaged. Always.
Dead branches come out completely, back to a live branch union. Do not leave stubs — a stub will not callus, and it becomes a rot entry point within two seasons. Use clean cuts just outside the branch collar (the slight raised ridge where the branch meets the trunk or parent limb). The collar is the tree's own healing tissue. Cutting into it removes the material the tree needs to close the wound.
After the three Ds: crossed branches. Two limbs rubbing each other is a wound compounding every year. Remove the weaker one — usually the one growing toward the centre of the tree. You are trying to open the canopy, not fill it in.
Then water sprouts. Those upright, fast-growing shoots that produce no fruit. Cut them at the base. On a tree that has not been touched in years, you may have dozens of them. Remove the worst this season and continue next year. Water sprouts can be removed through the growing season, unlike structural cuts.
Finally, height reduction. If the tree is at 20 feet and you want it back to something you can harvest from a standard orchard ladder, reduce the central leader and tall scaffold branches gradually. A manageable home orchard tree is around 10–12 feet. Do not top it in one pass.
A note on tool hygiene: keep pruning tools sharp and disinfected. Wipe blades with rubbing alcohol between cuts on any diseased wood. Apple scab and fire blight spread on contaminated tools — it is a small step that matters more on old trees with existing disease pressure. For help keeping your tools in shape, see our post on how to sharpen pruning shears.
The ISA Canada arborist directory is a good resource if you want a certified opinion on what the tree needs before committing to a renovation plan.
A few years back I was called in to look at an old apple tree in Surrey that a homeowner had attempted to prune on his own. He had taken the top off the central leader — flush, straight across — which is the one cut most likely to cause a watersprout flood. He had also removed a large scaffold branch with no attention to the collar; just cut straight back to the trunk. Two seasons later the callus had not formed and rot had set into that wound.
By the time I assessed it, what should have been a two-season renovation was a more complicated conversation about which scaffold branches were still structurally sound. The tree came through fine — but it took longer than it needed to, and cost more than it would have. The lesson is not "never prune your own apple tree." It is: learn the cuts before you make them, because the wrong cuts on an old tree are not easily undone.
How much can you remove in one season?
The 20–25% rule exists for good reason. Remove more than that and the tree responds by putting everything into regrowth — specifically water sprouts, which is the last thing you want on a tree you are already trying to slow down.
A severely neglected tree might need 40–50% removed total to get back to a proper structure. Split that over three seasons and the tree handles it well. Try to do it in one season and you will either stress the tree badly or trigger a watersprout response that undoes most of your work.
Nine out of ten renovation projects I see try to go too fast. The people who get the best results are the ones who are methodical about it, year by year.
The BC Ministry of Agriculture tree fruit guidance covers renovation pruning in more depth if you want the horticultural detail behind the 25% limit.
Year one, year two, year three: what to expect
Year one: You are removing structural problems. Dead wood, obvious crossing branches, the worst of the water sprouts. The tree will look better but not dramatically different. This is the foundation year. Your goal is structure, not beauty.
Year two: The canopy is opening up. More light is getting in. You can see where the tree is responding well — new healthy growth from the right branches — and where it is still throwing energy into water sprouts. Year two is also when the fruit starts to improve. Better size, better colour.
Year three: If you have been consistent, the tree starts producing properly again. Less fungal disease because air circulation has improved. This is the year most people say "I should have done this years ago." Which is fair enough. But you did it when you did it, and the tree is responding.
Some old trees do not respond this predictably. A tree that was hard-topped at some point in its history has already been set back. A tree with significant disease pressure may need fungicide management alongside renovation pruning. Expect the process to take the time it takes.
When not to call us
I will tell you this even though it is not optimal for our booking calendar.
If your apple tree is under 10 feet, in reasonable health, and just needs a light annual tidy — a pair of loppers, a folding pruning saw, and a couple of hours on a dry February morning. You do not need an arborist for that. Our guide to pruning fruit trees for winter covers the technique in detail.
If you are comfortable on a ladder and the main scaffold branches are at a reachable height, annual maintenance on an apple tree is genuinely DIY-able. Learn the branch collar cut, keep your tools sharp and clean, and you can maintain a modest apple tree yourself for years.
When you should call: the tree is over 15 feet and the major cuts are near the top. The scaffold branches require climbing to reach safely. You want a structural assessment before committing to a two-year renovation. There is any concern with the main trunk, scaffold unions, or root system.
A tree assessment runs $150 and gets credited toward any work we do. If the tree turns out to need nothing — or to be genuinely not worth saving — you will leave knowing that, and that is worth something too.
