Best Fertiliser for Sir Walter Buffalo Grass

Sir Walter Buffalo is one of the most popular lawns in Australia because it’s hardy, shade tolerant, and family friendly. But like all living plants, it needs regular feeding to stay green and healthy. Choosing the right fertiliser makes the difference between an average lawn and a lush, thriving one.

Here’s everything you need to know about the best fertilisers for Sir Walter Buffalo and how to use them throughout the year.

What Nutrients Does Sir Walter Buffalo Need?

Buffalo lawns respond best to fertilisers that balance three key nutrients:

• Nitrogen (N): Promotes strong green growth and colour.

• Phosphorus (P): Supports root development.

• Potassium (K): Improves overall strength, disease resistance, and drought tolerance.

Look for a fertiliser that includes slow-release nitrogen, so your lawn gets a steady supply of nutrients without sudden surges of growth.

Seasonal Fertiliser Guide for Sir Walter

Feeding your lawn at the right time of year is just as important as the product you choose.

• Autumn (March–May): Apply a balanced fertiliser to prepare the lawn for cooler weather.

• Winter (June–August): Growth slows, but applying an iron-rich fertiliser can keep colour.

• Spring (September–November): Use a nitrogen-heavy fertiliser to kick-start growth.

• Summer (December–February): Apply a potassium-rich fertiliser to handle Perth’s heat and drought.

• Use a spreader for even application.

• Combine fertiliser with soil conditioners like Watheroo Bentonite Clay and Soil Conditioner for deeper, stronger root systems.
