Problems with Sir Walter Buffalo Grass (And How to Fix Them)
Sir Walter Buffalo is Australia’s most popular lawn, loved for its toughness and shade tolerance. But like any grass, it can run into problems if it’s not cared for properly. The good news is — most of these issues are easy to fix, and with the right products your Sir Walter lawn will thrive in Perth conditions.
Let’s look at the most common problems and how to solve them.
1. Patchy or Thinning Lawn
The problem: Some homeowners notice bare patches or thinning areas in their Sir Walter lawn. This usually happens because of poor soil, compaction, or lack of nutrients.
The fix:
- Improve soil structure with Soil Conditioner and Watheroo Bentonite Clay – both help roots grow stronger.
- Aerate the soil using a Turf Cutter or Rotary Hoe before laying or repairing turf.
- Fertilise regularly with Baileys 3.1.1 Plus or Eco Prime Red to restore growth.
2. Dry or Brown Patches in Summer
The problem: Perth’s hot, dry climate can leave Sir Walter lawns looking stressed and brown if not watered correctly.
The fix:
- Use Eco Wet Wetting Agent to help water soak deep into sandy soils.
- Fertilise with Eco Prime Emerald for stronger summer growth.
- Make sure your irrigation is even across the whole lawn. For large jobs, hire a Motorised Wheelbarrow to make soil prep and watering easier.
3. Weeds Taking Over
The problem: Even tough lawns like Sir Walter can get invaded by weeds if neglected.
The fix:
- Apply a weed and feed treatment designed for buffalo lawns.
- Regular mowing at the right height (Sir Walter likes to be kept around 40–50mm) keeps weeds from spreading.
- Tools like the Complete Tools Package or Basic Tool Kit make weeding and lawn maintenance easier.
4. Lawn Looking Yellow or Lacking Colour
The problem: Yellowing usually means the lawn is hungry for nutrients, especially nitrogen and iron.
The fix:
- Fertilise with Eco Prime Red for nitrogen boost.
- Use Eco Prime Purple for balanced nutrition, especially in cooler months.
- Top dress with Multigrow to encourage new shoots and a greener look.
5. Thatch Build-Up
The problem: Over time, buffalo lawns can get thatchy, where dead grass builds up at the base. This can block water and nutrients from reaching the roots.
The fix:
- Scarify or lightly dethatch the lawn during spring.
- Follow up with fertiliser like Baileys 3.1.1 Plus to help it bounce back.
- Regular mowing at the right height prevents future build-up.
6. Shade Stress
The problem: While Sir Walter is the most shade-tolerant buffalo, very dense shade can still cause thinning.
The fix:
- Keep shady areas tidy — prune trees to let in more light.
- Use a soil booster like Watheroo Bentonite Clay for stronger root systems.
- Fertilise with Eco Prime Emerald to encourage healthy growth in lower light.
Tools That Make Lawn Care Easier
Maintaining your lawn is much simpler when you have the right equipment:
- Normal Wheelbarrow – for small turf jobs.
- Motorised Wheelbarrow – for larger areas or soil-heavy work.
- 8×5 Cage Trailer – handy for moving soil, mulch, and turf rolls.
- Power Tool Package – for tackling tougher prep and maintenance tasks.
