Sir Walter Buffalo grass is one of the most widely used soft leaf buffalo lawns in Australia due to its durability, shade tolerance, and low ongoing demands. While it is often described as easy to manage, proper fertilising and maintenance play a major role in how dense, green, and resilient the lawn becomes over time.
This guide explains how to fertilise Sir Walter Buffalo grass, outlines a proven Sir Walter Buffalo grass maintenance routine, and covers watering, mowing, seasonal care, and common lawn issues based on Australian conditions.
Understanding Sir Walter Buffalo Grass
Before looking at fertilising and maintenance, let’s understand how Sir Walter Buffalo grows and why it behaves differently from seeded grasses.
Sir Walter is a warm-season soft leaf buffalo grass that spreads through runners rather than seed. This growth habit allows it to form a thick lawn that suppresses weeds and holds moisture in the soil more effectively than many other turf types.
Key characteristics of Sir Walter Buffalo include:
- Broad, soft leaf blades with a deep green colour
- Strong drought tolerance once established
- Excellent performance in both full sun and shade
- Low allergenic properties compared to seeded grasses
These traits make Sir Walter Buffalo grass suitable for residential lawns across much of Australia.
How to Care for a New Sir Walter Buffalo Lawn
The way a Sir Walter lawn is handled in the first few weeks after installation has a direct impact on how well it establishes and performs long term.
During this early stage, the focus should be on consistent moisture, minimal traffic, and allowing roots to anchor into the soil rather than encouraging fast top growth.
Watering During Establishment
Newly laid Sir Walter turf needs regular watering to prevent stress while roots develop.
A practical watering approach includes:
- Week 1: Water morning and late afternoon to keep the soil moist
- Week 2: Reduce watering to once per day, ideally in the morning
- Weeks 3 to 4: Water every second or third day
To check whether the turf has established, gently lift a corner of a slab. Resistance indicates the roots have taken hold.
When to Mow Sir Walter Buffalo Grass
Mowing too early or cutting the lawn too short is one of the most common causes of weak growth in buffalo lawns.
Sir Walter Buffalo should only be mowed once roots are established and the turf has started actively growing.
For new lawns, the first mow usually occurs two to three weeks after laying. During this first cut, only a small amount of leaf should be removed.
Recommended mowing heights are:
- Full sun areas: 25 to 40 mm
- Shaded areas: 40 to 50 mm
Maintaining slightly longer leaf length in summer helps protect the soil and reduces moisture loss.
How to Fertilise Sir Walter Buffalo Grass Correctly
Fertilising provides the nutrients Sir Walter needs to maintain colour, density, and recovery throughout the year.
While Sir Walter Buffalo grass is capable of surviving with minimal feeding, regular fertilising supports healthier roots and more consistent growth, particularly in high-use lawns.
Choosing the Right Fertiliser
The most suitable option is a slow-release fertiliser formulated for buffalo lawns. These fertilisers feed the grass gradually and reduce the risk of leaf burn.
A quality fertiliser for Sir Walter typically contains:
- Nitrogen for steady leaf growth
- Iron to enhance green colour
- Potassium to support stress tolerance
Pro Tip: Avoid cheap, rapid-release sulphate of ammonia products on Buffalo. These can easily burn the broad leaf and lead to thatch build-up, which can cause sponginess later on.

When to Fertilise Sir Walter Buffalo in Australia
Timing fertiliser applications correctly is just as important as the product used.
In most Australian climates, fertilising three times per year is sufficient to maintain healthy growth.
The ideal fertilising periods are:
- Early Spring (September/October): To wake the lawn up from winter dormancy.
- Early Summer (December): To prepare the lawn for heat stress.
- Mid-Autumn (April/May): This is the most critical feed. It helps the lawn retain colour during winter and ensures it bounces back quickly the following spring.
In tropical or frost-free regions, fertilising during the dry season produces more consistent results.
Watering Sir Walter Buffalo Grass the Right Way
Sir Walter is drought-tolerant, but it still requires hydration to look its best. The goal is to encourage deep root growth.
Instead of watering lightly every day, water deeply once a week (or twice during extreme heat). This forces the roots to travel down into the soil profile to find moisture.
- Morning is Best: Water early (between 6 am and 9 am). This allows the water to soak in, but leaves the foliage time to dry out before nightfall, reducing the risk of fungal issues like Brown Patch.
- Hydrophobic Soil: If water pools on the surface and doesn’t soak in, your soil may have become water-repellent. Applying a high-quality soil wetter or wetting agent can fix this immediately, helping moisture penetrate the root zone.
Weed and Pest Control
Sir Walter Buffalo grass maintenance requires vigilance, especially regarding weeds.
Weed Control Warning
Critical: Buffalo grass is sensitive to certain herbicides. Never use a broadleaf weed killer containing Dicamba unless it clearly states it is “Safe for Buffalo.” Using the wrong chemical can kill your entire lawn.
- Bindii and Clover: Treat these in winter or early spring before they flower and seed.
- Winter Grass: Use a specific selective herbicide to target Winter Grass (Poa annua) without harming the Buffalo.
Pest Watch
- Lawn Armyworm: These caterpillars can strip a lawn of its green leaf in days. If you notice moths hovering over the grass at dusk, check for armyworms.
- African Black Beetle (Curl Grub): These larvae eat the roots. If patches of grass die and the turf lifts up easily like a loose carpet, you likely have a grub infestation that requires a granular insecticide.
Annual Sir Walter Buffalo Grass Care Calendar
A simple lawn care schedule makes maintenance easy to manage.
- Spring: Aerate the soil if compacted. Apply a slow-release fertiliser. Target young weeds.
- Summer: Water deeply. Mow frequently at a higher setting to shade the soil (keeping roots cool). Monitor for armyworm.
- Autumn: Apply a winter-prep fertiliser high in potassium. Apply pre-emergent herbicide to stop winter weeds.
- Winter: Minimal mowing. If you are in a frost-prone area, keep traffic off the lawn on frosty mornings to avoid leaf damage.
Common Sir Walter Buffalo Lawn Care Mistakes
Many Sir Walter lawn problems come from well-intentioned but incorrect maintenance habits.
One common issue is overwatering, which encourages shallow roots and reduces drought tolerance. Another frequent mistake is cutting the grass too short, especially in shaded areas where extra leaf length is needed for photosynthesis.
Using fertilisers not designed for buffalo lawns can also cause damage, as Sir Walter is sensitive to certain chemicals. Fertilising too soon after laying turf is another issue, as new roots need time to establish before nutrients are introduced.
By avoiding these mistakes, you’ll help your lawn stay stronger, maintain its vibrant colour, and perform well throughout the year.

Frequently Asked Questions About Sir Walter Buffalo Grass Care
How often should Sir Walter Buffalo grass be fertilised?
Sir Walter Buffalo grass benefits from fertilising around three times per year in most Australian climates. Early spring, early to mid-summer, and mid-autumn provide the best timing for nutrient uptake and balanced growth. Tropical regions often achieve better results by fertilising during the dry season rather than the wet season.
What is the best fertiliser for Sir Walter Buffalo grass?
A slow-release fertiliser formulated specifically for buffalo lawns suits Sir Walter best. Products containing balanced nitrogen, added iron, and potassium support leaf colour, root strength, and stress tolerance. Buffalo-safe fertilisers reduce the risk of leaf burn and chemical sensitivity.
How long after laying Sir Walter turf can mowing begin?
New Sir Walter Buffalo turf usually becomes ready for mowing after two to three weeks, depending on weather and care. Root establishment provides the key indicator. Resistance when gently lifting a turf corner confirms the lawn is ready for its first cut.
How often should Sir Walter Buffalo lawns be watered?
Established Sir Walter Buffalo lawns perform best with deep watering once or twice per week during warmer months. Soil type, temperature, and rainfall influence exact frequency. Cooler seasons generally require far less watering, especially in southern Australian regions.
What mowing height suits Sir Walter Buffalo grass?
Sir Walter Buffalo grass maintains its density and health at a medium mowing height. Full sun areas suit a height of 25 to 40 millimetres, while shaded areas benefit from slightly longer leaf growth between 40 and 50 millimetres. Longer blades improve shade tolerance and moisture retention.
Does Sir Walter Buffalo grass grow in shade?
Sir Walter Buffalo grass shows excellent shade tolerance compared to many other lawn types. Growth remains healthy with as little as three to four hours of sunlight per day, making it suitable for yards with trees, fences, or buildings casting shade.
When should fertiliser be avoided on Sir Walter lawns?
Newly laid Sir Walter Buffalo turf should not receive fertiliser until roots establish, which usually takes four to six weeks. Cold or frosty conditions also limit nutrient uptake, making fertilising less effective during those periods in cooler climates.
Why does Sir Walter Buffalo grass turn yellow?
Yellowing in Sir Walter Buffalo grass often relates to nutrient imbalance, compacted soil, or excessive watering. Iron deficiency commonly affects colour, while poor drainage can stress roots. A soil-friendly fertiliser and corrected watering habits usually improve colour over time.
Can weed killers damage Sir Walter Buffalo grass?
Some herbicides cause damage to buffalo lawns if they are not specifically formulated for soft leaf buffalo grass. Product labels should always confirm buffalo safety before application. Spot treatment and early intervention reduce the need for stronger chemicals.
