⚑ Do These This Week

1Apply Amgrow Wettasoil β€” you already have it. 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 Scotts Lawn Builder Buffalo at Bunnings β€” apply this week while autumn growth is still possible.
πŸ‚ Phase 1
Autumn β€” May 2026
Fix water penetration Β· fertilise Β· stabilise the lawn before winter
πŸ“… Week 1 β€” Do Now (Mid May)
Locate your Amgrow Wettasoil
DIYUrgent
You already have this. Check the label for the correct application rate and whether a hose-end sprayer or watering can is recommended.
πŸ’° Already purchased
Apply Amgrow Wettasoil β€” full lawn
DIYUrgent
Apply across the entire lawn (not just the bare patch) in the morning. Water in well immediately after. Very low toxicity β€” lawn is fine for kids once dry, usually within a few hours.
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
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. Do this on a non-retic day such as Monday or Friday. Morning only.
πŸ’° Free
Buy Scotts Lawn Builder Buffalo at Bunnings
DIY
Specifically the Buffalo variety (slow release granules). Do not over-apply β€” stick exactly to the rate on the bag or it can burn the lawn.
πŸ’° ~$25–45
Apply Scotts Lawn Builder Buffalo β€” full lawn
DIY
Spread evenly across the whole lawn. Immediately sweep any granules off paving β€” the iron stains. Water in well after applying. Kids & pets: keep off while wet, fine once dry (a few hours). Safe after that.
πŸ’° Free (already bought)
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
General lawn check β€” end of May
DIY
Look at the central zone β€” is it holding moisture better after the wetting agent? Any new green Buffalo growth appearing at the edges of the bare zone? The lawn will still look rough overall heading into winter β€” this is normal. Note any changes for reference.

❄️ 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.
πŸ’° Free
Aerate the bare zone β€” after first good rain
DIY or Pro
Wait until soil is moist after rain.
DIY: Push a garden fork 10–15cm deep every 15cm (~1 hour).
Hire: Coring machine from Kennards Hire, 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.
πŸ’° ~$20–30
πŸ“… July β€” Mid Winter Check
Mid-winter lawn check
DIY
Note how the lawn is tracking. Some winter grass is expected in the bare zone β€” healthy Buffalo will crowd it out naturally once spring arrives. No fertilising now β€” Buffalo is dormant. The lawn will look rough and thin through winter. This is completely normal.
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.
πŸ’° Free
πŸ“… August β€” Late Winter Check
Late winter check β€” start planning spring supplies
DIY
Winter grass in the bare zone is expected β€” the Buffalo will take over as it warms up. Use this as a planning prompt: check your Wettasoil supply for the September reapplication, and confirm you have enough Scotts Lawn Builder Buffalo for spring.

🌱 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
Second Amgrow Wettasoil application β€” full lawn
DIY
Repeat your May application across the whole lawn before summer heat arrives. Check your existing supply β€” if enough remains, no need to buy more. Same method as before: apply in the morning, water in well immediately after. Fine for kids once dry.
πŸ’° ~$0 if supply remains / ~$20–30 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.
πŸ’° Free
Apply Scotts Lawn Builder Buffalo β€” spring feed
DIY
Most important application of the year β€” Buffalo is actively growing again and will spread runners into the bare zone. Spread evenly, sweep granules off paving immediately, water in well. Kids & pets: fine once the lawn is dry, usually a few hours.
πŸ’° ~$25–45 if new bag needed
πŸ“… Every Week in October β€” Recovery Watering

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. 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.
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
