Maintaining a thriving lawn and garden in New South Wales takes more than just occasional mowing. With distinct seasonal patterns — from humid summers to cool, wet winters — knowing what to do and when can make all the difference. This NSW seasonal garden planner gives you a clear, practical lawn calendar to keep your outdoor spaces green, healthy, and looking their best year-round.

Summer (December – February): Growth & Water Management

Summer in NSW is all about heat and humidity, which means your garden’s focus shifts to hydration and pest control.

Lawn care checklist:

  • Mowing: Mow weekly, but keep grass slightly longer (around 5–6cm) to shade the soil and reduce evaporation.
  • Fertilising: Apply a slow-release nitrogen fertiliser early in summer to strengthen your turf.
  • Irrigation: Water deeply two to three times a week in the early morning to encourage strong roots.
  • Pest control: Watch for lawn grubs, armyworms, and fungal issues like dollar spot. Apply eco-friendly treatments if needed.

Garden tasks:

  • Prune summer-flowering plants after blooming to encourage new growth.
  • Mulch garden beds to lock in soil moisture and suppress weeds.
  • Inspect irrigation systems for leaks or clogs — efficient watering is essential during heatwaves.

Autumn (March – May): Repair & Prepare

As temperatures cool, your lawn recovers from summer stress — making this a great time for rejuvenation.

Lawn care checklist:

  • Fertilising: Apply an autumn fertiliser to boost root strength before winter dormancy.
  • Mowing: Gradually reduce mowing frequency as growth slows.
  • Aeration: Aerate compacted areas to improve drainage and nutrient absorption.
  • Overseeding: Reseed thin or bare patches to restore density before winter.

Garden tasks:

  • Trim hedges and shape shrubs before cold weather sets in.
  • Collect fallen leaves for compost or mulch.
  • Begin planting winter vegetables and flowering annuals.

Tip: Autumn is the perfect time to call in Brooksie’s Lawn Maintenance for professional aeration and fertilising — ensuring your lawn stays resilient through winter.

Winter (June – August): Maintenance & Protection

While growth slows in winter, maintenance remains key to preventing long-term issues.

Lawn care checklist:

  • Mowing: Mow lightly every 3–4 weeks to keep the lawn tidy.
  • Weed control: Apply a selective herbicide to manage broadleaf weeds.
  • Fertilising: Use a winter blend high in potassium for disease resistance.
  • Pest watch: Keep an eye out for fungal growth due to damp soil.

Garden tasks:

  • Prune dormant trees and shrubs.
  • Clean and sharpen garden tools.
  • Plan your spring planting schedule — this is the calm before the growth surge.

Spring (September – November): Renewal & Growth

Spring is the season of renewal, when your garden and lawn burst back to life.

Lawn care checklist:

  • Fertilising: Apply a balanced, slow-release fertiliser in early spring to fuel rapid growth.
  • Mowing: Increase mowing frequency as growth picks up — always follow the one-third rule.
  • Aeration & dethatching: Remove thatch buildup to allow water and nutrients to penetrate.
  • Pest control: Treat any signs of curl grubs or aphids before they spread.

Garden tasks:

  • Replant garden beds with summer flowers and vegetables.
  • Mulch around trees and plants to retain moisture.
  • Check irrigation timers and systems before summer arrives.
