Knowing the right time to fertilise Sir Walter Buffalo lawn directly affects growth, colour, and turf density. Feeding during active growth strengthens the lawn, while fertilising during dormancy reduces results.
In most Australian regions, fertilising should align with the lawn’s active growth phase, starting in early spring and continuing through the warmer months. This guide provides a clear seasonal breakdown to help you apply fertiliser at the right stage of growth for stronger colour and thicker turf.
Best Time to Fertilise Sir Walter Buffalo Lawn: Seasonal Guide for Australia
There are three key times of year to fertilise your Sir Walter Buffalo lawn:
| Seasons | When to Fertilise | Typical Purpose |
| Early Spring | Once growth resumes | Primary feed to activate growth |
| Mid Summer | During active warm growth | Support ongoing vigorous growth |
| Early Autumn | If lawn still growing | Light feed before slowdown |
| Winter | Do not fertilise | Lawn is dormant |
Early Spring (Primary Application)
Early spring is the best time to fertilise. Once the weather starts to warm and you notice consistent new growth, it is time to apply your first feed.
Soil temperatures should be sitting around 15°C or higher. The lawn will begin greening up and mowing will become more regular. Apply a slow release fertiliser made for buffalo lawns and water it in well.

Mid Summer (Peak Growth Support)
Mid summer is the second key feeding period. During this time, Sir Walter Buffalo is growing at its fastest and can make good use of nutrients.
Apply fertiliser during steady warm conditions. Avoid spreading it during extreme heat or when the lawn is dry and stressed. To maintain strong colour and consistent coverage through summer, it is vital to fertilise and maintain Sir Walter Buffalo correctly by watering in the nutrients thoroughly after application.
Early Autumn (Warm Regions Only)
If the lawn is still actively growing in early autumn, a lighter feed can be applied. Growth should still be steady, and soil temperatures should remain warm.
Keep this application lighter than spring and summer feeds. If growth has slowed significantly, skip it and wait for spring.
Winter Dormancy (Do Not Fertilise)
Sir Walter Buffalo is a warm season grass, so it slows right down during winter. In cooler weather, growth becomes minimal or stops completely.
Do not fertilise during winter. Wait until temperatures rise and active growth returns in spring before feeding the lawn again.
When to Fertilise a Newly Established Sir Walter Buffalo Lawn
Newly laid or recently established Sir Walter turf requires a different approach. Wait at least 6 to 8 weeks after installation before applying fertiliser. This allows the roots to properly anchor into the soil.
Fertilise only once:
- The turf is firmly established
- You cannot easily lift the edges
- Active growth is visible
Use a gentle, slow release fertiliser suitable for new buffalo lawns. Avoid heavy applications during the early establishment phase. If turf is laid in late autumn or winter, delay fertilising until active growth resumes in spring.
Conclusion
The best time to fertilise Sir Walter Buffalo lawn is early spring, followed by a second application in mid summer. A light early autumn feed suits lawns that are still growing, while winter fertilising should be avoided.
By matching fertiliser timing with natural growth patterns, you support stronger roots, better colour and a thicker lawn across Australian conditions.
FAQs
How often should I fertilise Sir Walter Buffalo lawn?
Most lawns respond well to two feeds per year, in spring and summer. A third light application may suit lawns that remain active in early autumn.
Can I fertilise in winter?
No. Winter is not suitable for fertilising as the grass is dormant and will not respond properly.
What should I do after applying fertiliser?
Water the lawn thoroughly after spreading granular fertiliser to help nutrients move into the soil.
