Buffalo grass is one of the most popular lawn choices across Australia—and it’s easy to see why. With its soft leaf, shade tolerance, and relatively low maintenance needs, it’s a go-to option for families, pet owners, and homeowners wanting a lush, green lawn without constant upkeep.

But while buffalo grass is known for being hardy, it’s not completely trouble-free.

Like any lawn type, it can run into issues—especially if it’s not properly maintained or if conditions aren’t ideal. The good news? Most buffalo grass problems are easy to identify and fix once you know what to look for.

In this guide, we’ll walk through the most common buffalo grass problems in Australia—and exactly how to fix them.

Why Buffalo Grass Is So Popular in Australia

Before diving into the problems, it’s worth understanding why buffalo grass is so widely used.

Buffalo grass is loved for its:

  • Excellent shade tolerance
  • Soft, broad leaves (great for barefoot lawns)
  • Lower mowing requirements compared to couch
  • Strong resistance to weeds when healthy

However, these strengths don’t make it immune to issues—especially under stress.

Common Buffalo Grass Problems

1. Patchy or Uneven Growth

The Problem

One of the most common complaints with buffalo grass is patchy or thin areas across the lawn. This can make your yard look unhealthy and uneven.

Common Causes

  • Lack of sunlight (even though buffalo tolerates shade, it still needs some light)
  • Poor soil quality
  • Compacted soil
  • Inconsistent watering

How to Fix It

  • Improve sunlight exposure: Trim back overhanging trees if possible
  • Aerate the soil: This allows roots to breathe and absorb nutrients
  • Topdress with quality soil: Helps fill in low spots and improve growth
  • Water deeply and consistently: Encourage deeper root development

👉 Tip: Buffalo grass spreads via runners, so once conditions improve, it will naturally fill in bare patches over time.

2. Yellowing Grass (Nutrient Deficiency)

The Problem

If your buffalo lawn is turning yellow instead of staying lush green, it’s usually a sign something is off.

Common Causes

  • Nitrogen deficiency
  • Poor soil health
  • Overwatering or underwatering
  • Lack of fertiliser

How to Fix It

  • Apply a balanced fertiliser: Preferably one high in nitrogen
  • Follow a feeding schedule: Every 6–8 weeks during the growing season
  • Check watering habits: Avoid both soggy and bone-dry soil

👉 Tip: A slow-release fertiliser can help maintain consistent colour without overfeeding.

3. Weed Invasion

The Problem

While buffalo grass is naturally dense, weeds can still creep in—especially if the lawn is stressed or thin.

Common Weeds in Australia

  • Bindii
  • Clover
  • Winter grass
  • Broadleaf weeds

How to Fix It

  • Use a buffalo-safe herbicide: Not all weed killers are suitable for buffalo lawns
  • Maintain lawn density: Healthy grass is your best defence
  • Mow regularly: Prevent weeds from seeding
  • Fertilise properly: Strong grass crowds out weeds

👉 Tip: Always check herbicide labels—some products can damage buffalo grass.

4. Thatch Build-Up

The Problem

Thatch is a layer of dead grass and organic material that builds up between the soil and the grass blades. Too much thatch can block water and nutrients.

Signs of Thatch

  • Spongy lawn underfoot
  • Poor water absorption
  • Weak or shallow roots

How to Fix It

  • Dethatch (scarify) the lawn: Usually once every 1–2 years
  • Aerate regularly: Helps break down organic matter
  • Avoid over-fertilising: Excess growth can lead to thatch build-up

👉 Tip: Buffalo grass generally produces less thatch than couch, but it can still become an issue over time.

5. Lawn Pests (Grubs and Insects)

The Problem

Buffalo grass can sometimes fall victim to pests that damage roots and leaves.

Common Lawn Pests

  • Lawn grubs
  • Armyworms
  • Beetles

Signs of Pest Damage

  • Brown or dying patches
  • Grass lifting easily from the soil
  • Increased bird activity (they feed on grubs)

How to Fix It

  • Apply an appropriate insecticide: Choose one safe for buffalo lawns
  • Water after treatment: Helps the product reach the root zone
  • Act quickly: Pest damage can spread fast

👉 Tip: Regular lawn inspections can help catch infestations early.

6. Fungal Diseases

The Problem

Fungal issues can affect buffalo grass, especially in humid or wet conditions.

Common Diseases

  • Brown patch
  • Leaf spot
  • Dollar spot

Causes

  • Overwatering
  • Poor drainage
  • High humidity
  • Excess thatch

How to Fix It

  • Improve drainage: Aerate compacted soil
  • Water early in the morning: Avoid overnight moisture
  • Apply fungicide if needed: For severe cases
  • Reduce thatch: Improves airflow

👉 Tip: Prevention is key—healthy lawns are far less likely to develop fungal problems.

7. Overwatering or Underwatering

The Problem

Watering issues are one of the biggest causes of lawn problems in Australia.

Signs of Overwatering

  • Mushy soil
  • Fungal growth
  • Yellowing grass

Signs of Underwatering

  • Dry, brittle grass
  • Wilting or browning
  • Soil pulling away from edges

How to Fix It

  • Water deeply, not frequently: Encourages deep roots
  • Adjust for seasons: More water in summer, less in winter
  • Check soil moisture before watering

👉 Tip: Installing an irrigation system can help maintain consistency.

8. Scalping from Mowing Too Low

The Problem

Buffalo grass doesn’t like being cut too short. Scalping can stress the lawn and expose soil.

Signs

  • Brown patches after mowing
  • Uneven lawn appearance
  • Slow recovery

How to Fix It

  • Raise mower height: Buffalo prefers a higher cut than couch
  • Mow regularly: Avoid removing more than one-third of the leaf at once
  • Keep blades sharp: Prevent tearing

👉 Tip: A slightly longer lawn is healthier and helps retain moisture.

9. Compacted Soil

The Problem

Heavy foot traffic or clay soils can lead to compaction, making it hard for roots to grow.

Signs

  • Water pooling on the surface
  • Hard soil
  • Poor growth

How to Fix It

  • Aerate the lawn: Creates space for air and water
  • Add organic matter: Improves soil structure
  • Reduce heavy traffic where possible

👉 Tip: Compacted soil is a hidden issue that can affect overall lawn health.

A little ongoing care goes a long way in avoiding bigger issues down the track.

Final Thoughts

Buffalo grass is one of the best all-round lawn options for Australian homes—but like any grass, it needs the right care to stay healthy.

The good news is that most common buffalo grass problems—whether it’s patchiness, weeds, pests, or yellowing—are easy to fix with the right approach.

By understanding what causes these issues and acting early, you can keep your lawn looking lush, green, and resilient all year round.

Frequently Asked Questions

Yellowing is usually caused by nutrient deficiency, poor watering habits, or soil issues. Applying a nitrogen-rich fertiliser and improving watering can help restore colour.

Improve soil quality, aerate the lawn, and ensure adequate sunlight and watering. Buffalo grass will naturally spread and fill in gaps over time.

No, you should only use herbicides specifically labelled as safe for buffalo grass, as some products can damage it.

Water deeply once or twice a week in summer, and reduce watering in cooler months depending on rainfall.

Common pests include lawn grubs and armyworms. These can be treated with appropriate insecticides if detected early.
