How to Maintain Sir Walter Lawn in Perth and All Areas of WA?

Sir Walter Soft Leaf Buffalo is a low-maintenance lawn; however, in Perth and across WA, conditions including sandy soils and long, dry summers make correct maintenance essential. 

At Greenacres Turf Group, turf is cut fresh to order and delivered within 24 hours of harvest, which is key for successful establishment. From there, maintenance becomes a key factor to keep your lawn looking healthy.

Most lawns that struggle aren’t failing because of the turf itself. It usually comes down to a lack of care or maintenance. Once that’s corrected, Sir Walter performs very well in Perth and wider WA conditions.

How does Sir Walter Buffalo Grass grow in Perth??

Sir Walter doesn’t grow at a steady rate all year, and that’s where a lot of maintenance issues begin.

Through Spring and summer, the growth rate increases. That’s when correct mowing, watering, and fertilising make a visible difference.

In winter, turf goes dormant, and growth slows. Maintenance practices must change as correct care is vital during this time.

Maintaining Sir Walter lawn is simple with proper care, and reliable turf farms like Greenacres Turf Group provide comprehensive information and aftercare support.

How to Care for Buffalo Grass After Installation?

This stage is often underestimated, and correct care must be provided to support the long-term performance of the turf.

Right after installation, the focus should be on helping the turf establish successfully without any stress. Fresh-cut turf that’s laid correctly on a well-prepared site will take quickly, but it still needs consistent moisture and nutrients to settle in.

Reliable turf farms such as Greenacres Turf Group provide a comprehensive installation and maintenance guide that covers all the information you will require during this process, including watering schedules.

Ensure the turf stays moist, not saturated. If parts of the lawn dry out early, those areas will be under high stress and will struggle to establish. 

Four weeks post installation, apply a light application of an NPK, slow-release maintenance fertiliser to boost healthy turf growth. 

Avoid mowing too soon and at the correct height. It is best to wait until the lawn is anchored and cannot be lifted easily by hand.

What are the Watering Tips for Sir Walter Buffalo Lawn? 

Watering is a main factor that determines how well your lawn holds up through the Perth summers.

Once established, Sir Walter responds better to regular, deep watering rather than frequent light watering. This helps the roots grow down into the soil and avoid shallow-rooted lawns, which become easily stressed in hot, dry weather.

A practical approach to watering buffalo lawn in Perth conditions is:

• Apply 40mm of water per week, generally across 4 watering sessions, depending on weather and rainfall. 
• 10mm is the maximum amount of water to be applied each session as turf cannot absorb more than this at one time.
• Reduce or stop watering in Autumn and Winter as rainfall increases.
• Water early in the morning (5 am-9 am) so the lawn can dry during the day.
• Utilise wetting agents to allow efficient water retention and penetration

In Summer, with days of extreme temperatures (35-40°C), it is recommended to increase the application rate to 13mm per session to allow for the higher evaporation rate. Handwater between rostered days where required to reduce water stress in your turf.

If the lawn has been installed and maintained well, it will show early signs before water stress sets in. A dull blue-grey colour or slight curling of leaves is an early indicator that it needs more water.

Following a correct watering schedule is simple but important for your turf to stay green and healthy all year round.

What are the Correct Mowing Practices for Buffalo Lawn Health? 

Sir Walter must be mowed consistently to keep it in good condition.

The aim is to keep your lawn short while maintaining leaf coverage. This allows rapid recovery, keeps soil cool, protects the roots, and suppresses weeds. 

Basic mowing practices to remember:

• Change mowing height and frequency with the season
• Avoid removing more than ⅓ of the leaf when mowing. 
• Remove clippings: they can encourage disease and pests if left on the lawn.
• Do not cut too short:  it will weaken the turf and make it more vulnerable to stress. 
• Mow consistently: If grass is left to grow too long, it will cause issues. When cut, the lawn will be patchy, recover slowly, and weeds will easily grow through as thatch develops.

During the warmer months, mowing becomes more frequent as growth increases. In cooler periods, it will naturally slow down.

A steady approach works best for Sir Walter Buffalo:

• Summer: Mow every 7-10 days at a height of 15-20mm
• Winter: Mow every 3-4 weeks at a height of 20-25mm

Consistent and correct mowing is a key part of Sir Walter Buffalo maintenance.

What Should be the Fertilising Schedule for Strong Lawn Growth? 

In Perth and across WA, sandy soils don’t hold nutrients for long, and fertilising plays a steady supporting role.

This helps your lawn maintain a vibrant green colour, support continued optimum growth, and improve recovery from wear.

A basic fertilising schedule for strong lawn growth:

• Fertilise your lawn 4-6 times per year with a good quality, slow-release NPK (Nitrogen, Phosphorus, Potassium) maintenance fertiliser. 
• As a general rule, lawns should be fertilised with the change of every season. 
• If required, a second light application mid-spring and mid-summer will help. 
• Do not fertilise more than 6 times per year.

Some helpful tips:

• Always apply fertiliser to a dry lawn, and then water it well. This prevents the leaf from burning.
• Soil type can influence application rate:
• Poor sands require frequent but light applications
• Heavier or improved soils require less

At Greenaces Turf Group, we have a range of premium-quality turf care products available.
