How to fertilise buffalo grass

7 Minute(s) read

A healthy buffalo lawn needs regular feeding while it is actively growing. The right fertiliser helps support strong growth, healthy roots and rich green colour.

For Victorian buffalo lawns, including Sir Walter DNA Certified Buffalo, timing matters just as much as the fertiliser you choose. This guide explains when to fertilise, what nutrients to look for and how to apply fertiliser without damaging your lawn.

Why fertilising buffalo grass is important

Buffalo grass needs the right nutrients to maintain healthy growth, strong roots and its rich green colour. Regular fertilising replaces nutrients your lawn draws from the soil throughout the growing season.

A well-fed buffalo lawn is also better equipped to recover from mowing, foot traffic and seasonal stress. However, more fertiliser is not always better. The best results come from applying the right buffalo lawn fertiliser at the right time and rate.

When to fertilise buffalo grass

The best time to fertilise buffalo turf is during its active growing season, from spring through autumn. Warmer soil temperatures help the lawn take up nutrients and put them towards healthy leaf and root growth.

The right fertilisation methods should coincide with your seasonal maintenance. Therefore, avoid heavy fertiliser applications during winter. Buffalo grass slows its growth in Victoria’s cooler months, so it needs less feeding during this period.

Spring, summer and autumn fertilising

Spring is an ideal time for the first main fertiliser application as your buffalo lawn returns to active growth. A slow-release granular fertiliser can provide steady nutrition as growth increases.

During summer, fertilise when the lawn is healthy and has sufficient water. Avoid applying fertiliser to heat-stressed or dry turf.

An autumn application can help maintain lawn health before winter growth slows. Apply early enough for the buffalo grass to use the nutrients before colder conditions arrive.

How often should you fertilise buffalo grass?

As a general guide, fertilise an established buffalo lawn every 8–10 weeks during active growth. Your lawn's needs can vary depending on its condition, soil and the fertiliser you use.

Always follow the recommended application rate on the product label. Applying extra fertiliser will not necessarily give your lawn a faster boost and can damage the turf.

What is the best fertiliser for buffalo grass?

The best fertilisers for buffalo grass provide balanced nutrition that supports healthy roots, leaf growth and a dark green colour. Look for a lawn fertiliser suited to buffalo grass and follow its recommended application rate.

Different fertilisers suit different lawn care needs. Slow-release products provide nutrients gradually, while liquid or foliar products can deliver a quicker boost when used correctly.

Nutrients to look for

Check the fertiliser’s NPK ratio, which indicates its nitrogen, phosphorus and potassium levels. Nitrogen supports green leaf growth, while phosphorus and potassium contribute to root development and overall lawn health. It is important to use a fertiliser with a good NPK balance, such as 16-2-4.

Some buffalo lawn fertilisers also contain trace elements to support healthy growth. Always choose a product suitable for buffalo grass rather than applying unnecessary extra nutrients.

Slow-release, organic and liquid fertilisers

A slow-release granular fertiliser is a practical option for regular feeding because it releases nutrients gradually over time. This can provide consistent nutrition throughout the growing season.

Organic fertiliser can also support your lawn while contributing organic matter to the soil. Products containing ingredients such as seaweed may be used as part of a broader lawn care program.

How to apply fertiliser to buffalo grass

Correct application helps spread nutrients evenly across your buffalo lawn and reduces the risk of patchy growth or fertiliser burn. Check the product label first, as application rates and watering instructions vary between fertilisers.

Prepare and mow your lawn

Mow your buffalo grass before fertilising if needed, but avoid cutting it too short. Remove excess clippings, leaves and other debris so the fertiliser can reach the lawn evenly.

If you have a new buffalo lawn, check that the turf is established before starting a regular fertilising program. Newly laid turf has different feeding requirements from an established lawn.

Apply the fertiliser evenly

Measure your lawn and use the recommended amount of fertiliser for the area. For granular products, a fertiliser spreader can help achieve consistent coverage and prevent concentrated patches.

Walk across the lawn systematically so you do not miss areas or double-apply the product. Keep fertiliser off garden beds, paths and waterways, and follow all directions on the label.

Water after fertilising

Many granular fertilisers need to be watered in after application. This helps move the nutrients into the soil and reduces the chance of fertiliser granules sitting on the leaf and burning.

Water with sprinklers or your irrigation system, which provides more consistent results. Avoid applying fertiliser immediately before heavy rain, which can wash nutrients away before your lawn can use them.

Common fertilising mistakes to avoid

Feeding your lawn correctly is as important as choosing the right lawn food. Too much fertiliser or poor timing can damage buffalo grass rather than improve its health.

Over-fertilising

Applying more fertiliser than recommended can burn your buffalo lawn and cause excessive leaf growth. Always measure the area and follow the application rate on the product label.

Avoid using fertiliser as a quick booster for a struggling lawn. First check for other problems, such as watering issues, compacted soil, pests or weed competition.

Fertilising in winter

Buffalo is a warm-season grass, so its growth slows considerably through a Victorian winter. Fertilising heavily during this period provides little benefit because the lawn cannot use nutrients as effectively.

Focus your main feeding program on the warmer growing season. Winter lawn care should instead be tailored to your lawn's condition and any specific problems that arise.

Fertilising in unsuitable weather

Avoid fertilising during extreme heat, drought or before heavy rain. Fertiliser applied to stressed summer grass can cause further damage, while heavy rainfall may wash nutrients away.

Check the weather before fertilising and make sure your lawn has adequate moisture. Choosing suitable conditions gives the fertiliser a better chance to work effectively.

Tips for successful buffalo lawn fertilising

A good fertilising routine works best alongside regular watering, mowing and weed control. Pay attention to how your buffalo lawn responds rather than applying extra fertiliser whenever growth or colour changes.

Problems such as winter grass, crowsfoot or creeping oxalis need appropriate weed control. Fertiliser alone will not remove them and may encourage unwanted growth.

Test your soil

If your buffalo lawn struggles despite regular care, a soil test can help identify pH or nutrient issues. This can prevent unnecessary fertiliser applications and help you choose products based on what the lawn actually needs.

Soil testing guidance from Agriculture Victoria explains how to collect a representative soil sample for more useful results. Testing is particularly helpful before making significant changes to an established lawn care program.

Follow a regular fertilising schedule

Plan your main fertiliser applications around your buffalo lawn’s active growing season. In Victoria, this generally means feeding from spring through autumn and reducing fertiliser during winter.

Keep a simple record of when you fertilise and which product you use. When combined with appropriate mowing, watering, and weed control, a consistent schedule makes ongoing lawn care easier.
