The Best Time of Year to Prune Trees in Western Australia
Pruning your trees? Timing matters.
Pruning isn’t just about trimming a few branches, it’s about supporting long-term tree health, protecting your home, and keeping your yard safe and tidy. But what many WA homeowners don’t realise is that when you prune can have a major impact on how your trees respond.
At Harvey Tree Care, we provide pruning services across Harvey, Yarloop, Benger, Brunswick, Waroona, Burekup and surrounds. Here’s our guide to the best times of year to prune trees in Western Australia, and why it matters.
Summer pruning in WA (December to February)
Western Australian summers are hot, dry, and often stormy. Summer pruning is typically focused on safety and shaping, especially after rapid spring growth.
You might need summer pruning to:
- Remove storm-damaged or heat-stressed branches
- Thin out the canopy to allow airflow and reduce the risk of wind damage
- Control vigorous growth that’s blocking sunlight or becoming overgrown
- Clear branches hanging over roofs, gutters, sheds, or powerlines
However, it’s important not to over-prune in summer. Cutting back too much during extreme heat can put stress on the tree and expose it to sunburn or water loss. Our team knows how to prune safely and selectively in WA’s unique climate.
Autumn pruning (March to May)
As temperatures begin to cool, trees start to slow their growth. Autumn is the perfect time for lighter pruning and tidy-up work.
Common autumn pruning jobs include:
- Removing suckers and unwanted low branches
- Light shaping to prepare for winter dormancy
- Tidying hedges, fruit trees, and ornamentals
- Clearing away dead, crossing, or rubbing branches
This is also a great time to inspect your trees for damage or decay before winter storms arrive.
Winter pruning (June to August)
Winter is when many trees go dormant, especially deciduous varieties, making it the best time for more significant structural work. With the leaves gone and the tree at rest, we can clearly see its form and make larger cuts without stimulating new growth.
Winter pruning is ideal for:
- Structural pruning to improve long-term shape and strength
- Reducing the size of large or overgrown trees
- Removing dangerous limbs before heavy winter winds hit
- Training young trees to grow with strong, balanced structure
It’s also the best time to prune fruit trees like apples and pears, as well as ornamental deciduous trees that benefit from a hard winter cut.
Spring pruning (September to November)
Spring pruning focuses on encouraging healthy new growth after winter. It’s a great time to remove any remaining deadwood, shape hedges, and get your yard looking great for the warmer months ahead.
We often recommend spring pruning for:
- Tidying up frost-damaged tips
- Lightly shaping natives and evergreen trees
- Removing fast new shoots and water sprouts
- Refreshing hedges, topiary, and screening plants
However, be mindful of flowering trees and shrubs, many species bloom in early spring, so it’s best to wait until flowering is finished before pruning.
So… when should you prune your trees?
It depends on:
- The type of tree (native vs exotic, deciduous vs evergreen)
- Its size and location on your property
- Whether you’re pruning for safety, health, appearance, or fruit yield
That’s why it pays to speak with an arborist. Pruning too early, too late, or too harshly can cause irreversible damage, especially on native trees or those under stress from drought or pests.
