Why Tree Branches Grow Back Faster After Poor Pruning
Cutting branches back hard can seem like a quick fix, but it often creates a bigger problem later.
Many homeowners prune a tree because it has become too tall, too wide, or too messy. The goal is usually simple: make it smaller, safer, and easier to manage. But when pruning is done the wrong way, the tree can respond by growing back faster, thicker, and weaker than before.
At Harvey Tree Care, we often see trees across Harvey, Yarloop, Benger, Brunswick, Waroona and surrounding areas that have been cut back too harshly. What started as a tidy-up can quickly turn into dense regrowth, weak branches, and ongoing maintenance issues.
Here’s why poor pruning causes fast regrowth, and why professional tree pruning is the better long-term option.
Trees React to Stress
When a tree loses too much of its canopy at once, it treats the damage as a threat. Leaves are how trees produce energy, so when too many branches are removed, the tree tries to replace that lost foliage as quickly as possible.
This often leads to fast, messy regrowth around the cut areas.
You may notice:
- Long upright shoots
- Dense clusters of new growth
- Branches growing back in awkward directions
- A thicker canopy than before
- More frequent pruning needed each year
While this new growth can look strong at first, it is often poorly attached and more likely to fail during wind, heat, or storms.
What Counts as Poor Pruning?
Poor pruning is not just about cutting too much. It also includes cutting in the wrong place, at the wrong time, or without considering the tree’s natural structure.
Common poor pruning mistakes include:
Topping the tree
Topping is when the upper section of a tree is cut off to reduce height. It might make the tree shorter immediately, but it usually causes a burst of weak regrowth from the cut points.
These new shoots often grow quickly but do not form strong natural branch attachments.
Removing too much canopy
Taking too much foliage in one visit puts the tree under stress. This can trigger rapid regrowth as the tree tries to recover.
In WA’s hot conditions, over-pruning can also expose branches and trunk sections to sun damage.
Cutting branches in the wrong spot
Branches should be removed carefully near the branch collar, which is the natural swelling where the branch joins the trunk or main limb. Cutting too close or leaving large stubs can slow healing and increase the risk of decay.
Random cutting without a plan
Pruning should improve the tree’s shape, structure, and safety. Random cutting can leave the canopy unbalanced, which may increase the chance of branch failure later.
Why Fast Regrowth Is a Problem
Fast regrowth after poor pruning is not the same as healthy growth. Much of it is reactive growth, meaning the tree is trying to recover from stress rather than growing naturally.
This can create several issues.
The new branches are often weak
New shoots that grow from old pruning wounds are usually attached closer to the surface of the tree. They do not have the same strength as branches that developed naturally over time.
As these shoots get longer and heavier, they can become more likely to snap.
The canopy becomes dense and messy
Poor pruning often leads to a thicker canopy, not a lighter one. Dense regrowth can block sunlight, reduce airflow, and increase the weight sitting on already weakened branches.
This means the tree may need pruning again sooner than expected.
It can increase storm risk
A tree with weak regrowth and poor structure may be more vulnerable during high winds. Instead of solving a safety issue, poor pruning can create new hazards above roofs, sheds, fences, driveways, and outdoor areas.
It can affect long-term tree health
Large cuts, heavy canopy loss, and poor technique can leave trees exposed to pests, disease, and decay. Over time, this can shorten the life of the tree or make removal necessary.
Tree Lopping vs Proper Tree Pruning
Many people use the terms tree lopping and tree pruning as if they mean the same thing, but they are very different.
Tree lopping usually refers to cutting large sections of a tree back quickly, often without much focus on structure or long-term health. It may reduce the size of the tree in the short term, but it often causes the fast, weak regrowth mentioned above.
Professional tree pruning services are more careful and planned. The goal is to reduce risk, improve shape, and support the health of the tree.
We look at:
- Tree species
- Age and condition
- Branch weight and direction
- Canopy balance
- Nearby structures
- Long-term growth patterns
- Safety risks
This helps ensure the tree is pruned properly, not just cut back heavily.
What Is Epicormic Growth?
Epicormic growth is the fast shoot growth that often appears after a tree has been stressed or heavily cut. These shoots may grow from the trunk, larger limbs, or around old pruning cuts.
They are common after topping, harsh lopping, fire damage, drought stress, or storm damage.
Epicormic shoots are often:
- Fast growing
- Thin and upright
- Weakly attached
- Dense and crowded
- More likely to need future pruning
If your tree has lots of these shoots, it may be a sign that it was pruned too hard in the past.
How Professional Pruning Reduces Regrowth Problems
Good pruning is not about removing as much as possible. It is about removing the right branches for the right reasons.
An arborist may recommend:
Removing deadwood
Dead, damaged, or diseased branches can be removed to improve safety without putting unnecessary stress on the tree.
Reducing weight on heavy limbs
Rather than cutting a large limb off completely, careful weight reduction can make the branch safer while preserving the tree’s natural structure.
Thinning dense areas
Selective thinning improves airflow and light through the canopy. This helps reduce weight without triggering excessive regrowth.
Corrective pruning
If a tree has been poorly pruned in the past, corrective pruning may help improve structure over time. This is usually done gradually, rather than all at once.
Can a Poorly Pruned Tree Be Fixed?
In many cases, yes. But it depends on how much damage has been done.
If the tree has been topped or heavily lopped, it may need several rounds of careful pruning over a few years to improve its structure. The goal is to gradually remove weak regrowth, encourage stronger branch development, and reduce safety risks.
In some cases, if the tree has become too unstable or badly decayed, removal may be the safest option. An arborist can inspect the tree and recommend the best approach.
Signs Your Tree Has Been Poorly Pruned
You may be dealing with past poor pruning if you notice:
- A flat or unnatural tree shape
- Clusters of shoots around old cuts
- Large exposed pruning wounds
- Branches growing straight up from cut limbs
- Dense regrowth that keeps coming back
- Splitting or cracking near old cuts
- A tree that looks unbalanced or top-heavy
If any of these signs are present, it is worth having the tree assessed before more pruning is done.
Why Timing Matters
The timing of pruning also affects how a tree responds. Heavy pruning during hot WA summers can place extra stress on trees, especially if they are already dealing with dry soil, pests, or disease.
In many cases, light pruning can be done when needed for safety, but larger structural pruning is best planned around the species and season.
That is why using experienced local arborists matters. They understand how WA conditions affect tree health and regrowth.
Frequently Asked Questions
Why did my tree grow back thicker after pruning?
This usually happens when the tree was cut back too hard. The tree responds by producing fast regrowth to replace lost foliage.
Is fast regrowth a good sign?
Not always. Fast regrowth can be a stress response. These new shoots are often weaker than natural branches.
Can tree lopping damage a tree?
Yes. Heavy tree lopping can cause weak regrowth, decay, poor structure, and long-term safety issues.
Can Harvey Tree Care fix a badly pruned tree?
In many cases, yes. We can assess the tree and recommend corrective pruning or removal if the tree has become unsafe.
