Seasonal Maintenance Guide
- Prune Grevillea, Callistemon, and Hakea lightly by one-third immediately after flowering to encourage bushy growth and more flowers next season—do not cut into old wood
- Apply native-specific slow-release fertiliser (explicitly labelled low phosphorus—confirm NPK shows P below 2%) once per year in September
- Remove exotic weed seedlings urgently before they set seed—spring is when Cape weed, Paterson's curse, and annual grasses establish fastest
- Top up mulch to 100 mm depth using fine woodchip or leaf litter before summer heat arrives in November
- Service drip irrigation and test emitters before December—find blocked drippers now, not during a heatwave
- Monitor newly planted specimens for heat stress as October temperatures rise; adjust dripper output if wilting before noon
- Water newly planted specimens (under 18 months) deeply twice per week before 7 am; established plants rarely need supplementary watering unless temperatures exceed 40°C for multiple consecutive days
- Keep birdbaths topped with fresh water daily—wildlife mortality during heatwaves is significant and a full birdbath is the most impactful thing a garden can provide
- Prepare bushfire management plan for fire-prone areas: clear gutters, remove bark mulch within 3 m of the house, trim dry grass in January
- Harvest lemon myrtle, native mint, and bush tucker herbs during the growing peak
- Allow plants showing natural summer dormancy to rest—do not interpret this as drought stress; forced watering can trigger fungal root disease in stressed native roots
- Check nest boxes in January after breeding season—remove old nesting material to prevent mite build-up
- Best planting window in Australia—plant new natives from March with 6–8 weeks of warm soil before winter dormancy slows establishment
- Collect seed from Lomandra, Dianella, Acacia, and annual wildflowers in March before seed heads open—dry at room temperature, store in paper bags in the fridge
- Divide overcrowded Lomandra and Dianella clumps in April: lift entire clump, divide with a sharp spade, replant sections 300 mm apart
- Remove spent Banksia and Grevillea flower cones to improve appearance, but leave some on Banksia for cockatoos who excavate them for grubs
- Install new nest boxes before the July–August breeding season starts for many hollow-nesting species
- Apply a thin layer of fresh woodchip mulch in May to insulate soil through winter and suppress autumn weed germination
- Appreciate the core winter spectacle: flowering Banksias, Correas, winter-blooming Hakeas, and wattles beginning their July flush—the native garden is often at its most ecologically active in winter
- Plan and order new plants from specialist native nurseries in June for March planting—demand for provenance stock from reputable nurseries can mean 6–9 month wait times for specific species
- Protect frost-sensitive northern Queensland and WA species (Heliconia australasica, tropical Syzygium) with hessian wrap when Melbourne or tablelands NSW temperatures drop below –3°C
- No supplementary watering needed in southern regions June–August; natural rainfall maintains moisture in well-mulched beds
- Research local provenance species through ANPS (anps.org.au) state chapters—winter meetings and seed swaps are the best way to access genuinely local-provenance plants
- Clean and check wildlife nest boxes: remove old nesting material, repair entry hole if enlarged by predators, ensure box is stable before August nesting season begins
