A week-by-week checklist for restoring your Buffalo lawn. Tap each task to mark it done. Core problem: hydrophobic sandy soil preventing water penetration in the central zone.

Overall Progress 0 of 0 tasks

⚑ Do These This Week

1Soil wetting agent β€” apply across the entire lawn now. This is the root cause of the bare patch.
2Check reticulation in daylight β€” run it manually and watch if the bare central zone is actually getting water.
3Buy Destiny Herbicide β€” winter grass is germinating right now. The window closes in a few weeks.
πŸ‚ Phase 1
Autumn β€” May 2026
Treat winter grass Β· fix water penetration Β· stabilise the lawn before winter
πŸ“… Week 1 β€” Do Now (Mid May)
Buy soil wetting agent
DIYUrgent
Product: Penetraide Re-Entry or Yates Waterwise Soil Wetter (2L concentrate). Available at Bunnings or any garden centre.
πŸ’° ~$35–45
Apply soil wetting agent β€” full lawn
DIYUrgent
Use a hose-end sprayer for even coverage across the entire lawn (not just the bare patch). Water in well immediately after. Do this in the morning.
Run reticulation in daylight β€” check coverage
DIYUrgent
Turn the system on manually and watch where the water lands. Is the central bare zone being reached? Note any misaligned or blocked heads.
πŸ’° Free
Fix any sprinkler heads (or call a retic tech)
DIY or Pro
If the centre isn't being covered, adjust heads yourself or book a retic technician for a 1-hour visit. This could be the single biggest fix.
πŸ’° Free DIY / $100–150 pro
Buy Destiny Herbicide (for winter grass)
DIYTime sensitive
Product: Destiny Herbicide (pronamide-based) or Kerb Granules β€” both safe on Buffalo. Available at Lawn Solutions Australia, some Bunnings, or online.
⚠️ Do NOT use Roundup or any non-selective herbicide β€” it will kill your Buffalo.
πŸ’° ~$40–60
Apply Destiny to affected/bare areas
DIYTime sensitive
Apply only to the bare and affected zones where winter grass (Poa annua) is emerging. Follow label instructions carefully. The window to treat effectively closes in a few weeks.
πŸ“… Week 2 β€” Still May (Wed/Sun retic days continue as normal)
Hand water bare zone β€” Session 1 (non-retic day, morning)
DIY
~20–30 mins on the central bare area with a hose or sprinkler attachment. Do this on a non-retic day such as Monday or Friday. Morning only.
πŸ’° Free
Buy and apply Autumn Fertiliser
DIY
Product: Lawn Solutions Autumn/Winter Fertiliser or Scotts Lawn Builder Autumn/Winter. Low-nitrogen, potassium-rich blend β€” potassium strengthens roots heading into winter. Apply at the recommended rate, do not over-apply. Water in afterwards.
πŸ’° ~$25–40
πŸ“… Weeks 3–4 β€” Late May
Hand water bare zone β€” Session 2 (non-retic day)
DIY
Second supplementary hand water session this month. Morning only, ~20–30 mins on the central zone. Choose a day that is not your Wed or Sun retic day.
πŸ’° Free
Hand water bare zone β€” Session 3 (non-retic day)
DIY
Final extra hand-water session for May. Morning only, ~20–30 mins on the central zone.
πŸ’° Free
Check winter grass treatment result
DIY
Inspect the treated areas. Winter grass should be yellowing or dying back. If fresh regrowth is visible, spot-treat again with Destiny. The lawn will look rough overall β€” this is expected at this time of year.

❄️ Phase 2
Winter β€” June to August 2026
Improve soil structure Β· aerate Β· let Perth rainfall do the work
πŸ“… June 1 β€” Start of Winter
Turn off reticulation controller
DIY
Water Corporation ban begins June 1. Switch the controller to off. Perth winter rainfall is normally sufficient for Buffalo. Only hand water if there has been no rain for 2+ consecutive weeks β€” and even then, just one light session.
πŸ’° Free
Aerate the bare zone β€” after first good rain
DIY or Pro
Wait until soil is moist after rain, then aerate the bare and central areas.
DIY: Push a garden fork 10–15cm deep every 15cm (~1 hour).
Hire: Coring machine from Kennards Hire β€” half day.
Pro: Book a lawn aeration service.
πŸ’° Free (fork) / $80–150 hire / $150–250 pro
Apply Gypsum / Soil Improver
DIY
Product: Yates Gypsum Clay Breaker or Richgro Penetrant Soil Improver. Spread across the entire lawn and bare zone. Rain will work it in naturally over winter, breaking down the hydrophobic layer long-term.
πŸ’° ~$20–30
πŸ“… July β€” Mid Winter Check
Inspect for returning Winter Grass β€” spot treat if needed
DIYIf needed
Look for fine, lighter green Poa annua regrowth in the bare zone. If present, apply Destiny to those spots again. No fertilising this month β€” Buffalo is dormant. The lawn will look rough and thin. This is completely normal.
πŸ’° ~$0 (remaining Destiny)
Emergency hand water β€” only if no rain for 14+ days
DIYOnly if needed
If there is an unusually dry stretch, give the lawn one light hand water session in the morning. Perth winters rarely need this, but worth noting.
πŸ’° Free
πŸ“… August β€” Late Winter Check
Final winter grass spot check and treat if needed
DIYIf needed
One last check for Poa annua before spring warms things up. Spot treat any remaining patches. Start planning your spring supplies β€” pre-emergent and fertiliser should be purchased in early September.

🌱 Phase 3
Spring β€” September to November 2026
Stimulate Buffalo recovery Β· lock out weeds Β· re-turf if needed
πŸ“… Early September β€” Pre-Spring Prep
Apply Pre-Emergent Herbicide
DIY
Product: Lawn Solutions Onset Pre-Emergent or OxaFert. Apply before warm-season weeds germinate as soil warms. Timing is key β€” do this before soil consistently reaches 18Β°C. Protects the recovering lawn through summer.
πŸ’° ~$40–60
Second Soil Wetting Agent application β€” full lawn
DIY
Repeat your May application across the whole lawn before summer sets in. Your 2L bottle from May should still have some left. Same method: hose-end sprayer, water in well immediately after.
πŸ’° ~$0 (remaining bottle) or ~$35 if new bottle needed
πŸ“… October 1 β€” Reticulation Resumes
Switch reticulation back on β€” increase to 15–20 min
DIY
Reticulation ban lifts October 1. Increase session duration from 10 min β†’ 15–20 min on your Wed & Sun schedule. The longer soak helps penetrate the sandy soil now that it has been treated.
πŸ’° Free
Apply Spring Fertiliser
DIY
Most important fertiliser of the year β€” Buffalo is actively growing again.
Product: Lawn Solutions Premium Fertiliser or Scotts Lawn Builder Spring/Summer. Apply at recommended rate across whole lawn. Water in well.
πŸ’° ~$40–60
πŸ“… Every Week in October β€” Recovery Watering
Hand water recovering zone β€” Week 1 of October (non-retic day)
DIY
~20 mins on the central recovering area. Morning only. Choose a day that is not your Wed or Sun retic day.
πŸ’° Free
Hand water recovering zone β€” Week 2 of October
DIY
~20 mins on the central recovering area. Morning only, non-retic day.
πŸ’° Free
Hand water recovering zone β€” Week 3 of October
DIY
~20 mins on the central recovering area. Morning only, non-retic day.
πŸ’° Free
Hand water recovering zone β€” Week 4 of October
DIY
~20 mins on the central recovering area. Morning only, non-retic day.
πŸ’° Free
πŸ“… October / November β€” Final Assessment
Assess Buffalo runner spread β€” mid October
DIY
Look for new Buffalo runners spreading inward from the healthy edges. If more than ~50% of the bare zone has new green coverage, let it continue naturally β€” no re-turfing needed. If less, proceed to re-turfing.
Re-turf bare zone if recovery is insufficient β€” early November
DIY or ProOnly if needed
If less than ~50% has recovered by early November, patch with new turf rolls. Variety: Sir Walter or Palmetto to match your existing grass. For ~10–15 sqm: turf ~$80–120 + top dressing ~$50. DIY laying is straightforward.
πŸ’° $150–200 DIY / $350–500 with pro labour
Optional third wetting agent application β€” January 2027
DIYOptional
If the summer is harsh and stress signs appear (central browning again), apply a third soil wetting agent in January. Same method and product as before.
πŸ’° ~$35 if needed
