When to Prune Trees in Sydney: A Seasonal Guide

Sydney's mild climate gives you more pruning windows than colder cities — but it also means fungal disease pressure is constant from October through March. Here's a month-by-month guide.

Autumn (March–May)

What to prune: deciduous trees as they start dropping leaves; maples, liquidambars, plane trees. Light dead-wooding on evergreen natives.

Avoid: heavy structural work on flowering trees that bud in autumn (camellia, magnolia).

Winter (June–August)

The main pruning window. Most deciduous and dormant trees prune cleanly during winter. Eucalypts, jacarandas (after flowering), fruit trees (after harvest), and most ornamental trees.

What to prune: structural pruning, crown thinning, crown lifting, formative pruning on young trees, hedge trimming hard cuts.

Avoid: citrus during cold snaps; pruning frost-tender species.

Spring (September–November)

What to prune: early spring is the second-best window after late winter. Hedge maintenance, shaping, and light dead-wooding all work well.

Avoid: heavy cuts on actively flushing growth — wait for the new leaves to harden off.

Summer (December–February)

The window most homeowners get wrong. Sydney summers are humid and fungal disease pressure is high. Open pruning wounds attract canker, dieback and root rot pathogens.

What to prune: dead-wooding only. Storm damage. Emergency structural work. Light hedge trimming on Lilly Pilly and murraya.

Avoid: heavy structural pruning, crown reduction, anything that makes large open cuts.

The 30°C rule

Don't prune anything above 32°C. The tree is shedding water through the cuts, and the heat stress compounds. Wait for the next cool-down.

The wet-weather rule

Don't prune anything in or just before sustained wet weather. Open wounds in wet conditions are an open invitation to fungal infection.

Emergency exceptions

Storm damage, structural failure, dangerous deadwood — these get pruned the day they're identified, regardless of season. The risk of leaving them outweighs the season.
