πŸ‚ Phase 1
Autumn β€” May 2026
Fix water penetration Β· fertilise Β· stabilise the lawn before winter
πŸ“… Week 1 β€” Mid May βœ“ Already done
Buy Amgrow Wettasoil (replenish)
DIY
New bottle purchased to replenish the one that was almost empty.
πŸ’° $20.79 βœ“ purchased
Apply Amgrow Wettasoil β€” full lawn (first application)
DIY
Applied last week across the entire lawn. Core fix for the hydrophobic sandy soil.
Replace controller battery and test reticulation in daylight
DIY
New battery being installed. Run the system manually in daylight and watch where the water actually lands. Check if the central bare zone is being reached β€” it may not have been running for some time due to the dead battery.
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 4kg at Bunnings
DIY
4kg bag covers up to 250mΒ² β€” more than enough for your ~25–36mΒ² lawn, with plenty left for the spring application.
πŸ’° $37.98 βœ“ purchased
Buy full-size garden fork at Bunnings
DIY
Full-size fork you can step on β€” needed to reach 10–15cm depth for effective June aeration.
πŸ’° $69 βœ“ purchased
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
Second Amgrow Wettasoil application β€” full lawn
DIY
Repeat the application from week 1. Given how hydrophobic your soil was, a second dose in late May ensures the soil is properly conditioned before winter rain arrives. Same method β€” apply in the morning, water in well. Fine for kids once dry.
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
Wait until soil is moist after rain, then use your garden fork. Push 10–15cm deep every 15cm across the bare zone (~1 hour). One session is enough for the season β€” sandy soil doesn't need repeated aeration.
πŸ’° Free (fork already purchased)
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. You already 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
Third Amgrow Wettasoil application β€” full lawn
DIY
Third and final scheduled application, before summer heat and reticulation resume. Check your existing supply β€” if enough remains, no need to buy more. 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
πŸ“… Mid October β€” Spring Feed
Apply Scotts Lawn Builder Buffalo β€” spring feed
DIY
Most important application of the year β€” Buffalo is actively growing and spreading runners into the bare zone. Spread evenly, sweep granules off paving immediately, water in well. Kids & pets: fine once dry, usually a few hours.
πŸ’° Free (bag already purchased)
πŸ“… Every Week in October β€” Recovery Watering
Hand water recovering zone β€” Week 1 of October
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. If less, proceed to re-turfing.
Apply Yates Weed 'n' Feed Buffalo β€” target clover areas
DIY
Apply ~4–6 weeks after the spring fertiliser feed. By late October the Buffalo will be strong and actively growing β€” exactly the conditions required by the label. Targets the clover you can see in the back corner. Do not apply to any bare or stressed areas. Kids & pets: keep off until spray is dry, then fine.
πŸ’° Free (already owned)
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 fourth Wettasoil application β€” January 2027
DIYOptional
If the summer is harsh and stress signs appear (central browning again), apply a fourth soil wetting agent in January. Same method and product as before.
πŸ’° ~$35 if needed
