1. Army Worms & Lawn Grubs (The #1 Summer Killer)
Where we see it most: New estates in Pakenham, Officer, Clyde, Cranbourne East and Lynbrook.
Symptoms: Sudden brown patches that spread overnight, small green/black pellets (frass), moths flying up when you walk on the lawn.
Fast fix:
- Apply Acepryn or Yates Grub Kill + Grub Guard in late afternoon.
- Water it in lightly.
- Most lawns recover fully within 10–14 days.
2. Dollar Spot Fungus (Looks Like Bleach Spots)
Most common in: Older Buffalo lawns in Cranbourne, Hampton Park, Lynbrook and Narre Warren.
Triggers: Night watering, high humidity and low nitrogen.
Fast fix:
- Apply a nitrogen-rich fertiliser (e.g. Buffalo PRO).
- Switch to early morning watering only.
- One application of Heritage MAXX or Mancozeb usually clears it in 7–10 days.
3. Brown Patch / Rhizoctonia (Large Brown Rings or Patches)
Hot spots: Kikuyu and Couch lawns in Berwick, Beaconsfield, Narre Warren South and Hallam.
Caused by: Over-watering, poor drainage and warm humid nights.
Fast fix:
- Stop watering for 5–7 days to let the soil dry out.
- Apply Heritage MAXX or Bayfidan fungicide.
- Core aeration in autumn helps prevent recurrence.
4. Dry Patch / Hydrophobic Soil (Water Runs Off)
Everywhere in new estates: Officer, Clyde, Cranbourne West, Pakenham Lakeside and Lynbrook.
Symptoms: Water beads on the surface and runs away, leaving brown patches even after watering.
Permanent fix:
- Apply a good wetting agent (SaturAid, Lawn Soaker or Penterra) every 6–8 weeks during summer.
- Most clients see major improvement after the first two applications.
5. Couch & Kikuyu Invasion into Buffalo Lawns
Common in: Berwick, Narre Warren, Hallam, Dandenong, Hampton Park and Keysborough.
Why it happens: Couch and Kikuyu are aggressive runners. Even a small piece left after edging can spread quickly.
Control (not complete eradication):
- Hand-pull or spot-spray with a selective herbicide safe for Buffalo (e.g. Bin-Die or Amgrow Chemi-Kill).
- Repeat every 4–6 weeks in spring and summer.
- Keep your Buffalo thick and healthy — it will naturally crowd out most invaders.
