Sir Walter Buffalo Grass: Characteristics, Cost and Care

Sir Walter buffalo grass is Australia's most popular lawn variety. Over 135 million square metres have been sold since 1997. If you are choosing a new lawn or trying to understand what you already have, this guide covers what makes it different, how it compares to other varieties, what it costs, and how to care for it.

Not all Sir Walter is equal. The name is widely used, but only turf carrying the DNA Certified mark is the genuine article. This matters when buying, and it matters for long-term performance. Must Have Maintenance handles turf installation and lawn maintenance across Melbourne's eastern and south-eastern suburbs. Whether buying a new lawn or managing an existing one, the information below gives you a clear picture of what to expect.

What Is Sir Walter Buffalo Grass?

Sir Walter buffalo grass is a warm-season turf variety developed in the mid-1990s by Brent Redman in the Hunter Valley, New South Wales. Bred for Australia's diverse conditions including full sun, deep shade, extreme heat, frost, and drought, it entered the market in 1997 and has not been surpassed in overall performance since.

It is a stoloniferous grass, meaning it spreads by above-ground runners called stolons. This growth habit is what gives the variety its self-repairing capability. When a section is damaged or worn, surrounding runners grow across to fill the gap without intervention.

What does DNA Certified mean?

In 2015, Lawn Solutions Australia introduced DNA testing to protect buyers from imitations. Genuine DNA Certified turf is grown exclusively by accredited producers and tested to confirm it is the original variety. When purchasing, look for the DNA Certified logo and confirm the seller is an LSA accredited member. Non-certified turf sold under the name may not deliver the same performance.

Sir Walter Buffalo Grass: Key Characteristics

Sir Walter consistently performs across the conditions that challenge other turf varieties. The table below summarises its key attributes at a glance.

Source: Characteristic ratings based on performance data from the Bureau of Meteorology climate classification for Melbourne and turf industry performance benchmarks.

Shade tolerance

Shade tolerance is one of Sir Walter's most valued characteristics. Most varieties struggle below 60 to 70% shade cover. Sir Walter can thrive with as little as three hours of direct sunlight per day. This makes it the default choice for properties with tree canopy, overlooking structures, or south-facing lawns.

Drought resistance

The deep root system draws moisture from the subsoil long after surface conditions have dried out. An established lawn can reduce surface heat by up to 10 degrees Celsius. Once established, Sir Walter needs watering only once or twice a week in typical conditions.

Self-repairing and low maintenance

The tight growth habit suppresses most weeds by crowding them out before they can establish. Its stolon-based spread means the lawn fills bare patches without reseeding. Mowing frequency is lower than kikuyu and couch because Sir Walter grows at a moderate rate rather than aggressively.

Sir Walter Buffalo Grass vs Other Popular Varieties

Choosing the right turf variety comes down to your property's conditions, how much maintenance you want to do, and how the lawn will be used. The comparison table below covers the five most common grass types installed in Melbourne properties.

Note: Ratings are relative comparisons based on typical performance in Melbourne's cool-temperate climate. Individual results vary depending on soil type, preparation, and ongoing care.

Sir Walter vs Kikuyu

Kikuyu is the most common lawn in Melbourne by installation volume, largely because it is cheap to buy and establishes quickly. However, it is highly invasive, spreads aggressively into garden beds, and requires more frequent mowing and edging than Sir Walter. In shaded areas, kikuyu struggles badly. Sir Walter outperforms it in almost every condition except cost at installation.

Sir Walter vs Couch

Couch grass is durable and handles drought well, but it goes almost completely dormant and brown in winter. It also performs poorly in shade. Sir Walter maintains its green colour through winter and handles shade that would eliminate couch entirely. For most Melbourne residential properties, Sir Walter is the stronger choice.

Sir Walter vs Zoysia

Zoysia is slow to establish and slow to repair, but it is very low-maintenance once settled. Sir Walter grows faster, repairs itself more quickly, and handles a wider range of conditions. Zoysia suits properties with stable, low-traffic situations. Sir Walter is the better choice for active family lawns.

How Much Does Sir Walter Buffalo Grass Cost in Melbourne?

Sir Walter buffalo grass typically costs between $13 and $18 per square metre from an accredited supplier. Retail slab formats at major hardware stores carry a higher per-m² rate but suit patch repairs or smaller areas.

Installation costs depend on the area size, the condition of the existing surface, and whether levelling or soil preparation is needed. Most properties also require turf underlay or soil amendment before the new lawn can establish properly.

What affects the total cost?

• Area size: larger orders typically attract a lower per-m² price from suppliers
• Soil preparation: compacted, uneven, or contaminated soil adds to the total
• Removal of existing lawn or debris before new turf can be laid
• Turf underlay and topsoil to support root establishment
• Ongoing care in the first six to eight weeks while the lawn establishes

Is Sir Walter the Right Choice for Your Property?

Sir Walter suits most residential and commercial properties. Its combination of shade tolerance, drought resistance, and low maintenance means it outperforms other varieties across the widest range of conditions. For properties with strict water budgets, it is one of the few grass types endorsed in government guidelines on water-efficient landscaping. There are situations, however, where alternatives are worth considering.

Sir Walter is a strong fit when:

• Your property has partial or dappled shade from trees, fences, or structures
• You want a lawn that stays green through summer without constant watering
• The lawn will be used by children or pets and needs to withstand regular traffic
• You want to minimise ongoing maintenance, mowing frequency, and chemical use
• You have allergy sufferers in the household

You may want to consider alternatives when:

• Your budget is the primary constraint. Couch and kikuyu cost less at installation
• The area receives no direct sunlight at all. Even Sir Walter needs at least three hours of direct sun per day
• You want a synthetic alternative with zero ongoing maintenance requirements

If a natural lawn does not suit your situation, synthetic grass installation is an alternative worth considering. Must Have Maintenance installs synthetic turf across Melbourne with the same fixed-price, no lock-in approach.

How to Care for Sir Walter Buffalo Grass

Sir Walter buffalo maintenance is genuinely low compared to most other varieties. Low maintenance is not no maintenance. A consistent seasonal routine keeps it dense, healthy, and self-sustaining over the long term.

Mowing height

Keep Sir Walter at 30 to 40 mm in warmer months and slightly longer, around 40 to 50 mm, through winter. Cutting below 25 mm risks scalping, which removes the stolons and creates bare patches that take longer to repair. Use a sharp blade and never remove more than one third of the leaf length in a single mow.

Watering

A newly laid Sir Walter lawn needs consistent watering for the first six to eight weeks while roots are establishing. Water daily for the first two weeks, then reduce to every second or third day as the lawn takes hold. Once established, Sir Walter only needs watering once or twice a week during summer. Deep, infrequent sessions are more effective than light daily watering.

Fertilising

Fertilise Sir Walter twice a year: once in spring as growth resumes and once in autumn before the lawn slows for winter. A slow-release lawn fertiliser with balanced nitrogen, phosphorus, and potassium works well for both applications. Avoid fertilising during peak summer heat or winter dormancy. Must Have Maintenance delivers fertilising services across Melbourne on the correct seasonal schedule as part of a regular lawn maintenance programme.

Aeration

Sir Walter responds well to annual lawn aeration in spring. Aerating breaks up compacted soil and allows water, oxygen, and nutrients to reach the root system more effectively. Properties with heavy clay soil or high foot traffic benefit most from aeration. Without it, even a well-watered and fertilised lawn can thin out over time.

Weed control

Sir Walter's tight growth habit naturally suppresses most weeds. If weeds do appear, a selective broadleaf herbicide is safe for use on buffalo grass, but always check the label confirms buffalo compatibility before applying. Spot-treating early prevents weeds from spreading into the lawn.For a complete seasonal lawn care plan, read our guide to lawn maintenance in Melbourne covering all four seasons for all common Melbourne grass types.

Frequently Asked Questions

What is the difference between Sir Walter and buffalo grass?

Sir Walter is a specific variety of buffalo grass, not a separate species. Buffalo grass is the broad category. Sir Walter DNA Certified is the most popular buffalo variety in Australia, developed in the mid-1990s and sold under strict DNA certification to protect buyers from imitations. When people say buffalo grass, they often mean Sir Walter specifically, because it accounts for the vast majority of buffalo turf sold in Australia.

Which is better, buffalo or kikuyu?

For most Melbourne residential properties, Sir Walter buffalo outperforms kikuyu across nearly every measure. Sir Walter handles shade, requires less mowing and edging, is not invasive to garden beds, and has a softer leaf. Kikuyu is cheaper at installation and establishes quickly, but it is aggressive, spreads into unwanted areas, and goes dormant in shade. Buffalo is the better long-term lawn.

How short should you cut Sir Walter buffalo grass?

Keep Sir Walter at 30 to 40 mm through the warmer months and 40 to 50 mm in winter. Never cut below 25 mm. Cutting too short removes the stolons that run just above the soil surface, which damages the lawn's ability to repair itself and creates bare patches. Never remove more than one third of the leaf blade in a single mow.

Will dead buffalo grass grow back?

In most cases, yes. Sir Walter's stolon-based growth means it can recover from drought stress, brown patches, and wear damage if the underlying stolons are still intact. Water first and wait two weeks before assessing whether recovery is happening. If large sections remain dead after watering, aeration and overseeding may be needed. A professional assessment can identify whether the lawn can be recovered or whether replacement is the better option.
