Turf Maintenance 2024


  • General Guidelines:
    • Begin mowing when your turf cannot be easily lifted from the soil, typically 2-3 weeks after laying.
    • Remove lawn clippings, especially if the leaf is over 30mm, to prevent burning and killing the lawn below. If using a mulch mower, rake up visible clippings after mowing.
    • Mowing frequency is related to the type and amount of fertilizer applied. Follow the recommended fertilizing guidelines to reduce mowing.
    • Never remove more than ⅓ of the grass blade height in a single mowing. Keep mower blades sharp for a clean cut and to prevent turf bruising.
    • Regular mowing at the recommended height ensures a thick, healthy, carpet-like lawn.
  • TifTuf Bermuda:
    • Requires regular mowing until established. During summer, mow frequently to reduce scalping.
    • Recommended mowing height: 23-25mm with a cylinder mower, notch 3 with a rotary mower.
  • Nullarbor Couch:
    • Requires mowing once per week year-round. Mow at 15-20mm.
    • Nullarbor has high thatch characteristics and may show scalping after mowing.
  • Sir Walter DNA Certified Buffalo:
    • Requires mowing every 7-10 days in summer and every 14-21 days in winter.
    • Recommended height: 30-40mm in sunny areas, 45-60mm in shaded areas.
    • Sir Walter does not show scalping after mowing.
  • Sir Grange Zoysia:
    • Requires 50% less mowing than other varieties. Mowing frequency varies with the season.
    • Recommended height: 15-20mm with a cylinder mower, 20-40mm with a rotary mower.
    • Can be left uncut for up to six months in cooler seasons but may require mowing every ten days during summer.
  • Empire Zoysia:
    • Requires mowing 10-15 times in spring/summer and very little to none in autumn/winter.
    • Recommended height: 20-30mm in sunny areas, 40-50mm in shady areas.
    • Note: In winter, keep all grass types mowed approximately 10mm longer than suggested summer heights.
    • Annually dethatch in spring by lowering mowing height and removing most leaf material to encourage deeper root growth and healthier lawns.
  • Zoysia Australis:
    • Requires minimal mowing, typically every 4-6 weeks during the growing season.
    • Recommended height: 20-30mm. In cooler months, mowing frequency can be reduced even further.
    • Zoysia Australis is highly drought-tolerant and maintains its lush green color with less frequent mowing.


  • Apply fertiliser and water well every 6-8 weeks year-round. Light, frequent fertilizing is better than heavy fertilizing, which can lead to excessive leaf growth and thatching.
  • Use a fertiliser with a moderate to high Nitrogen (N) value to enhance lawn appearance.
  • Reapply fertiliser 4 weeks after installation to replace nutrients lost during heavy watering. Continue every 6-8 weeks as recommended.


  • Adjust watering based on weather conditions. When fully established, water only when the lawn shows signs of stress, such as wilting or losing color.
  • To develop a drought-tolerant lawn, water deeply but less frequently to encourage deep root growth.
  • Occasionally aerate your lawn with a garden fork to allow water to penetrate deeply.

Weed Control

  • Pre-Emergent Herbicides:
    • Apply pre-emergent herbicides in early spring and autumn to prevent weed seeds from germinating.
    • Choose a product suitable for your turf type and follow the manufacturer’s instructions.
  • Post-Emergent Herbicides:
    • Use post-emergent herbicides to treat visible weeds. Spot-treat weeds to avoid damaging your lawn.
    • Select a herbicide that targets the specific weeds present in your lawn.

Pest Management

  • Common Lawn Pests:
    • Identify common pests such as Armyworms.
    • Monitor your lawn regularly for signs of pest damage, such as brown patches or chewed grass blades.
  • Pest Control Measures:
    • Use appropriate insecticides or natural pest control methods to manage infestations.
    • Encourage beneficial insects that prey on lawn pests.

Soil Health

  • Soil Testing:
    • Conduct a soil test every 2-3 years to determine nutrient levels and soil pH.
    • Adjust your fertilization and lime application based on soil test results.
  • Soil Amendments:
    • Apply organic matter, such as compost, to improve soil structure and fertility.
    • Use gypsum to improve soil drainage and reduce compaction.


  • Benefits of Aeration:
    • Aeration helps reduce soil compaction, improves water and nutrient absorption, and promotes root growth.
    • It is especially beneficial for high-traffic areas and heavy clay soils.
  • Aeration Schedule:
    • Aerate your lawn once a year, ideally in spring or autumn.
    • Use a core aerator to remove plugs of soil and allow air, water, and nutrients to reach the roots.


  • Why Dethatch:
    • Thatch is a layer of dead grass, roots, and debris that can build up on your lawn, preventing water and nutrients from reaching the soil.
    • Dethatching helps remove this layer, promoting healthier grass growth.
  • Dethatching Methods:
    • Use a dethatching rake or a power dethatcher to remove thatch.
    • Dethatch your lawn in late spring or early autumn when the grass is actively growing.

Seasonal Care for the Sunny Coast

  • Spring (September – November):
    • Begin mowing, apply pre-emergent herbicides, and fertilise.
    • Aerate and dethatch if needed.
  • Summer (December – February):
    • Maintain a regular mowing and watering schedule.
    • Watch for signs of pests and apply post-emergent herbicides as necessary.
  • Autumn (March – May):
    • Continue mowing and watering as needed.
    • Fertilise and apply pre-emergent herbicides.
    • Aerate and overseed if necessary.
  • Winter (June – August):
    • Mow less frequently and keep the grass slightly taller.
    • Reduce watering, but ensure the lawn receives enough moisture to avoid winter stress.
