The Complete Buffalo Grass Care Guide for Melbourne

Buffalo grass is the dominant lawn type across Melbourne's northern suburbs, from Diamond Creek and Eltham through to Greensborough and Warrandyte. It is popular for good reason - it is drought-tolerant, wear-resistant, relatively disease-free, and reasonably shade-tolerant compared to other warm-season alternatives like Kikuyu or Couch.

However, Buffalo is not a "set and forget" grass. It has specific needs throughout the year, and even experienced gardeners sometimes get the fundamentals wrong, which leads to a decline in lawn quality. This guide covers everything you need to know to keep Buffalo grass looking thick, green, and healthy year-round in the Melbourne climate.

Buffalo Grass Varieties in Melbourne

Sir Walter (Buffalograss): The most common Buffalo variety in Victoria. Coarser texture than newer varieties, very hardy, excellent wear tolerance, and good shade performance. It does go dormant and brown off in winter, which is normal. Sir Walter is extremely forgiving of maintenance mistakes and remains the go-to choice for most properties.

Sapphire Buffalo: A newer, finer-textured variety bred for better appearance and slightly better shade tolerance than Sir Walter. Darker green colour than Sir Walter. Marginally softer underfoot. More expensive to install initially but potentially superior long-term. Performance is very similar to Sir Walter with typical Melbourne maintenance.

Palmetto: An American Buffalo variety gaining popularity in Australia. Fine texture similar to Sapphire, excellent shade tolerance (perhaps the best among Buffalo varieties), and very attractive appearance. Can be slightly less wear-tolerant than Sir Walter in high-traffic areas. Rarer in Victoria than Sir Walter or Sapphire.

For the purposes of this guide, general Buffalo management principles apply to all three varieties, with specific notes where they differ.

Mowing Buffalo: Height and Frequency

Correct mowing height is critical. Buffalo has a natural growing pattern where runners spread laterally along the ground. Too short, and you cut through the runners and stress the plant. Too high, and you end up with a shaggy, unattractive lawn.

Spring (September-November): Mow at 35-40mm height. This is when Buffalo puts on its best growth. Mow every 7-10 days at this height. The fine clippings break down quickly and return nutrients to soil.

Summer (December-February): Raise the height to 45-50mm as temperatures climb. Buffalo growth slows dramatically in extreme heat. Mow every 14-21 days. The taller height shades the soil and helps Buffalo cope with heat stress. In a very hot year, you might only need one or two summer mows.

Autumn (March-May): Maintain 35-45mm height. Mow every 10-14 days as Buffalo rebounds from summer. This is an important recovery period where the grass thickens back up. Feed and mulch during this season if you have not already.

Winter (June-August): Raise height slightly to 40-45mm and mow every 21-28 days, or even less if growth is minimal. Many properties go 4-6 weeks without a winter mow. Buffalo naturally slows dramatically in cold months and may even brown off entirely during very cold snaps. This is not a problem - it is dormancy, not death. The grass will green up again in spring.

Fertilising Buffalo in Melbourne

Avoid the fertilising mistakes many people make: Applying fertiliser in midsummer forces soft new growth during the season when Buffalo needs to be tough and drought-resistant. Applying too much nitrogen creates lush foliage that is more disease-prone and thatch-building.

The right Buffalo fertilising schedule:

• April (autumn transition): Apply a balanced slow-release fertiliser (roughly equal NPK, something like 10-10-10 or 12-4-12). This feeds the grass as it recovers from summer and prepares it for winter. This is an important application.
• June or July (winter): Optional light application of slow-release if growth is still visible. Many properties skip this. Buffalo growth is minimal in winter.
• September (spring): Apply a balanced slow-release fertiliser (10-10-10 or similar). This feeds the explosive spring growth ahead. Absolutely do not apply high-nitrogen fertiliser here - it will force tender growth vulnerable to disease.
• Skip December-March entirely: No fertilising in summer and early autumn. Buffalo is in survival mode and does not need encouragement to grow.

Organic vs. synthetic: Both work well on Buffalo. Organic slow-release products (like blood and bone or pelletised chicken manure) feed soil microbes and build organic matter, but they work more slowly. Synthetic slow-release products (granular urea-based or resin-coated) deliver faster results. A combination approach (organic in autumn, synthetic in spring) is ideal if budget allows.

Liquid fertilisers: Liquid feeds can provide a quick nutrient boost, but they need to be applied every 4-6 weeks. Once-yearly solid slow-release applications are more practical for most people.

Shade Tolerance

Buffalo is reasonably shade-tolerant compared to other warm-season grasses, but it is not a shade specialist. Sir Walter tolerates 50-60% partial shade reasonably well. Sapphire and Palmetto are slightly more tolerant, managing 60% shade adequately.

Under deep shade (more than 70% shade): Buffalo will thin out and eventually fail. Consider alternatives like Soft Leaf Buffalo (if you want to stay in the Buffalo family) or shade-tolerant broadleaf ground covers (mondo grass, liriope, or similar).

Shade management: If you have areas that are becoming thin, consider:

• Pruning tree canopies to increase light penetration
• Thinning hedges or screening that is creating shade
• Aerating shaded areas to improve soil health (shade areas are often compacted as well)
• Mulching around trees rather than trying to maintain thin turf underneath

Common Buffalo Problems and Solutions

Brown patch fungus: The most common Buffalo disease, particularly in spring and autumn when temperatures are moderate and humidity is high. Brown patches appear (often circular) with a darker border. Often starts in poorly drained areas or where air circulation is poor.

Prevention is better than cure: improve air circulation by pruning overhanging branches, avoid overhead watering in the evening (which leaves foliage wet overnight), ensure good drainage, and do not overwater. If brown patch appears, reduce watering frequency, apply a fungicide if severe, and improve air circulation. It usually resolves on its own as the season changes.

Winter dormancy and browning: Buffalo naturally goes dormant in cold weather. This is not a disease or problem - it is the grass protecting itself. Dormant lawns turn tan or brown. In very cold years, dormancy is more severe. The grass will green up again in spring. Do not panic-feed or overwater trying to keep it green - this causes more problems than it solves.

Thatch buildup: Buffalo builds thatch (dead grass and plant material) if not managed properly. A thin thatch layer (under 10mm) is actually beneficial, but thick thatch (over 20mm) prevents water and nutrients from reaching the root zone. If your lawn feels spongy and water runs off rather than soaking in, thatch is the issue.

Solution: Dethatch annually in early autumn (March) using a dethatcher or power rake. This removes the accumulated dead layer and improves water and nutrient penetration. Follow dethatching with fertiliser and watering to encourage recovery.

Bare patches: Usually caused by heavy foot traffic, shade, disease, or inadequate watering. Repair in autumn (March-April) or spring (September) when soil temperatures are ideal for germination. Prepare the area (loosen soil, remove weeds and debris), overseed or lay turf runners, water regularly until established.

Weeds in Buffalo: A thick Buffalo lawn crowds out most weeds naturally. If weeds are appearing, the lawn is probably thin or stressed. Address the underlying cause (mowing frequency, fertilising, watering, shade) rather than just treating weeds chemically. That said, occasional spot spraying of persistent weeds is fine.

Winter Care for Buffalo

Winter is when Buffalo essentially shuts down. This does not mean you stop caring for it:

• Raise mowing height to 40-45mm. This protects the crown (where new growth emerges) from cold damage. Lower heights expose the growing point and can damage it.
• Mow less frequently. Every 21-28 days or even longer. If it barely needs cutting, do not cut it.
• Do not overwater. Buffalo does not need much water in winter. Overwatering waterloggs soil and can promote fungal disease. Assume rainfall will handle it unless you have a dry spell.
• Do not fertilise. Buffalo has minimal growth and cannot utilize fertiliser in winter. Save fertiliser for autumn or spring when the grass is actively growing.
• Do not rake or scarify heavily. Aggressive mechanical work in winter can damage dormant grass. Light cleanup is fine - just avoid aggressive treatments.

Seasonal Buffalo Care Checklist

March-April (Early Autumn): Aerate if needed, dethatch if thatch is over 15mm, fertilise with balanced slow-release, top-dress if lawn is uneven, overseed thin areas.

May-June (Winter): Minimal mowing, minimal watering, raise mowing height, monitor for disease, clear debris.

July-August (Late Winter): Continue minimal maintenance, prepare for spring by planning any renovation work.

September (Spring): Begin regular mowing schedule again, lower mowing height to 35-40mm, fertilise with balanced product, increase watering frequency gradually.

October-November (Late Spring): Weekly to fortnightly mowing, watch for thatch buildup, treat any spring-emerging weeds early.

December-February (Summer): Raise mowing height to 45-50mm, increase mowing interval to 2-3 weeks, maintain deep infrequent watering, watch for brown patch.

Frequently Asked Questions

My Buffalo has gone brown in winter - is it dead?

Almost certainly not. Buffalo naturally enters dormancy in cold months and browns off. This is normal and expected. The grass is still alive, just dormant. In spring, as soil temperatures warm, the green colour returns. If dormancy is very severe (completely brown with no green whatsoever), check that watering is adequate and that there is no disease present. Typically, dormant brown Buffalo is perfectly healthy.

How long does Buffalo take to establish after installation?

Buffalo turf pieces or runners root within 2-3 weeks if watered regularly and not subject to heat stress. However, full establishment (where it has spread and knitted together completely) takes 8-12 weeks. During establishment, water regularly (daily or every second day initially, then backing off gradually) and avoid heavy foot traffic. Avoid mowing until the new turf is firmly rooted (usually 3-4 weeks).

Can I plant Buffalo in summer?

You can, but autumn (March-April) or spring (September) installation is far better. Summer installation requires intensive watering through the establishment period (every 1-2 days) and the new grass will struggle in heat stress. Spring or autumn installation requires less intensive care and the grass establishes much more reliably.

How often should I aerate Buffalo?

Once annually in early autumn (March) is ideal if the soil is compacted. If your soil is naturally loose and well-draining, every 2-3 years may be sufficient. High-traffic areas should be aerated every year. Check by digging a small hole - if soil is hard to penetrate and compacted, aerate.

Is Buffalo better than Kikuyu?

This is a common question. Buffalo is slower-growing, lower-maintenance, and more refined-looking than Kikuyu. Kikuyu grows faster and is more aggressive, which can be an advantage in very harsh conditions or on difficult sites, but also means higher maintenance (more frequent mowing). For most suburban properties in Diamond Creek, Eltham, and Nillumbik, Buffalo is the better choice.
