Great question — timing your tree pruning correctly in Adelaide’s climate is critical for tree health, safety, and regrowth.

✅ Best Time to Prune Trees in Adelaide (General Rule)

🌳 Late Autumn to Winter (May to August) — IDEAL FOR MOST TREES

This is the best and safest time to prune most deciduous and many evergreen trees in metropolitan Adelaide and the Hills.

Why winter is best:

• Trees are dormant, reducing stress
• Disease and pest activity is low
• Structural issues are easier to see without dense foliage
• Promotes strong spring regrowth
• Less sap bleeding in most species

Best for:

• Structural pruning
• Safety pruning
• Storm preparation
• Large limb removal
• Tree shaping and weight reduction

⚠️ When You Should Avoid Heavy Pruning

❌ Mid–Late Spring (October–November)

• Trees are in active growth
• Pruning causes excessive stress
• Sap loss is high
• Pruning at this time can:
  • Reduce flowering
  • Attract pests
  • Increase disease risk

✅ Safe Pruning at ANY Time of Year (If Needed)

Some pruning is acceptable year-round, including:

• ✅ Dead, damaged, or dangerous limbs
• ✅ Storm-damaged branches
• ✅ Blocking powerlines, roofs, or driveways
• ✅ Hazard reduction for safety

If there is any immediate risk, pruning should be done immediately — regardless of season.

🌸 Special Adelaide Tree-Type Exceptions

✅ Flowering Trees

• Prune immediately after flowering
• Examples:
  • Jacarandas
  • Bottlebrush
  • Flowering cherries
• This ensures you don’t remove next year’s flower buds.

✅ Fruit Trees

• Most prune best in winter
• Light shaping can be done after harvest
• Avoid heavy pruning in extreme summer heat

✅ Native Australian Trees (Gums, Eucalypts)

• Best pruned in late winter to early spring
• Avoid heavy pruning in high humidity or summer heat (increases disease risk)

⚠️ Palms

• Can be trimmed any time of year
• Only remove:
  • Dead fronds
  • Dangerous hanging fronds
• Never over-prune live green fronds

🌡️ Pruning & Adelaide’s Heat

Avoid major pruning during:

• Extreme heatwaves (35°C+)
• Prolonged dry spells without irrigation

Fresh cuts expose trees to:

• Sunburn
• Moisture loss
• Pest invasion

✅ Quick Summary (Great for Website Use)

• Best overall time: Late Autumn to Winter (May–August)
• Emergency pruning: Any time of year
• Flowering trees: Prune after flowering
• Fruit trees: Winter is best
• Natives: Late winter–early spring preferred
