Assessing the Problem: Common Causes of Patches in Grass 

Patchy lawns can result from underlying problems ranging from inadequate watering and soil compaction to pest infestations or disease outbreaks. By analysing your lawn and soil conditions, which Joondalup Turf Farm can support you with, you’re better equipped to revive its health and achieve a lush appearance.

Underlying Soil Issues

Healthy grass starts with healthy soil and timely fertilisation. Compacted soil, poor drainage, or nutrient deficiencies can often lead to uneven growth and patchiness. 

Pests and Diseases 

Insects and diseases can wreak havoc on your lawn. Grubs, fungi, or pests can cause visible damage, leaving your lawn patchy and unhealthy. Pest control measures, such as regular inspections and targeted treatments, can safeguard your lawn from the impact of insects and diseases. Promoting good airflow can also create an environment less conducive to developing harmful pests and fungi.

Incorrect Watering 

Overwatering or underwatering can both contribute to patchy lawns. Understanding your grass type, monitoring soil moisture levels, and adjusting your watering schedule helps to maintain a healthy lawn. Using smart irrigation systems or rain sensors can also prevent overwatering or underwatering, ensuring the best conditions for your specific grass type.


Preparing for Lawn Patch Repair 

Once you’ve assessed the problem that is causing patches in your grass, it’s time to prepare for the solution. Follow these steps for successful lawn repair.

Soil Testing 

Assess the overall health of your lawn by evaluating the soil for nutrient levels and pH balance. This information will guide you in selecting the appropriate fertilisers or soil amendments to promote optimal growth. Joondalup Turf Farm offers expert advice on soil health, ensuring you choose the right fertilisers for your lawn. 

Clearing Debris 

Remove any debris, thatch, or dead grass from the patchy areas. This allows for better seed-to-soil contact during the repair process. Loosen the soil using a rake to enhance water and nutrient absorption. Consider overseeding the patchy areas with grass seeds suitable for your region and lawn type.


Aerate your lawn to reduce compaction and improve water and nutrient absorption. Relieving compaction enhances water and nutrient absorption while stimulating microbial activity in the soil, creating a lawn environment that encourages root development and better lawn health. 


Repairing your Patch Lawn 

Residential Landscapes

For small patches, overseeding is an excellent solution. It involves spreading grass seed over existing turf to fill bare spots and enhance grass density. Choosing a high-quality grass seed blend tailored to your specific lawn type is important to ensure it’s compatible with your existing grass variety. This addresses patchiness and contributes to a more visually appealing lawn by introducing new, healthy grass shoots.

Maintaining a Healthy Lawn

Now that you know how to fix a patchy lawn, establishing a consistent routine for ongoing lawn care is vital to sustaining its health. Regular tasks such as mowing at the appropriate height, fertilising according to seasonal needs, and promptly addressing any emerging issues contribute to the vibrancy and longevity of your lawn.

Proper Watering 

Follow a consistent watering schedule, considering your grass type and weather conditions. Striking the right balance is crucial, as overwatering wastes resources and creates an environment that can lead to diseases and patchy growth. By staying mindful of your lawn’s unique requirements and adapting your watering routine accordingly, you can contribute to your grass’s overall health and resilience.

Lawn Mowing 

Selecting the appropriate mowing height for your grass type is a key aspect of lawn maintenance. Regular mowing promotes healthy growth by stimulating lateral grass shoots and prevents thatch build-up. Adhering to the recommended mowing heights for your specific grass variety provides a professional-looking lawn while creating an environment conducive to lush grass growth.

Nutrient Management 

Continue to fertilise your lawn based on soil test recommendations. Addressing specific nutrient needs identified through soil testing provides your grass with the elements necessary for better growth and colour. Appropriate fertilisation and healthy soil conditions encourage lush greenery and protect your lawn against stressors, contributing to its overall visual appeal and longevity.

How Often Should You Mow Your Lawn?

Maintain the ideal height of your Wintergreen Couch grass between 15-30mm to prevent weeds and ensure a neat appearance. Regular mowing keeps your lawn tidy, helps to remove weeds, and promotes healthy growth.

Wintergreen Couch grass benefits from a schedule of regular mowing. Adjust the mowing height based on the season, allowing for more control and optimal growth during the active and dormant periods and a slightly higher cut during periods of stress, such as summer heat.
