Seasonal Maintenance Guide
- Prune shaped hedges and cloud-form shrubs before the main growth flush begins in October
- Apply low-phosphorus native-friendly slow-release fertiliser to any Australian native inclusions
- Refresh gravel and rake dry garden patterns after winter rain moves stones
- Service water feature pump and filtration before summer heat increases algae risk
- Plant new camellias, Japanese maples, and groundcovers while soils are warming but not yet hot
- Apply 100 mm of coarse composted wood mulch to all garden beds before the December heat
- Water deeply twice weekly before 8 am to minimise evaporation and comply with most council restrictions
- Install temporary shade cloth (50%) over Japanese maples during predicted heatwaves above 38°C
- Top up water features daily in hot weather; use recycled water where permitted
- Rake gravel gardens to maintain patterns disturbed by heavy summer storms
- Avoid any fertilising during peak heat—risk of fertiliser burn is high in December–January
- Monitor bamboo containers weekly to prevent runners escaping from drainage holes
- Peak visual season in Melbourne and highland gardens—minimal intervention, maximum observation
- Collect fallen maple leaves promptly to prevent mat formation over moss or mondo grass
- Plant new specimens into warm soil with 6 weeks before winter slows establishment
- Divide and replant overcrowded mondo grass and liriope clumps
- Drain and clean pond filters after summer biological load before cooler weather reduces algae
- Order bare-root Japanese maples and camellias for late-June to July planting while dormant
- Prune deciduous Japanese maples and Ginkgo while fully dormant—late July is ideal in Melbourne
- Plant bare-root maples, camellias, and azaleas directly into prepared acid soil
- Clean and treat timber structures (gates, pavilion, benches) with oil or penetrating stain
- Appreciate camellia flowering—the core winter spectacle of southern Australian Japanese gardens
- Protect frost-sensitive Nandina in Canberra and alpine-adjacent gardens with hessian wrap below –5°C
- Minimal watering needed in southern regions; Melbourne soils typically remain moist June–August
