Brown patches in your lawn can be caused by various factors, ranging from environmental stressors, cultural practices, to pest and disease infestations.
One common cause of brown patches is overwatering or poor drainage. Both of which can lead to waterlogged soil and root suffocation, resulting in brown, water-soaked areas. On the contrary, underwatering can also cause brown patches, as grass becomes stressed and goes dormant to conserve moisture.
Soil compaction, heavy foot traffic, or excessive thatch buildup can restrict root growth and nutrient uptake leading to brown, thinning areas.
Fungal diseases such as Brown Patch or Dollar Spot cause circular brown patches to appear on the lawn’s surface, usually during hot and humid weather.
Pest infestations including Lawn Grubs also damage grass roots and cause brown patches to develop.
Identifying the underlying cause of brown patches is essential for implementing targeted solutions and restoring the health and vitality of your lawn.

Preventing lawn diseases requires a combination of proactive measures aimed at promoting turf health and minimising favourable conditions for fungal pathogens (diseases).
1. Maintain proper lawn care practices.
o Mow at the appropriate height,
o Water your lawn deeply, and avoid repetitive morning sessions,
o Reduce excessive nitrogen fertilisation which encourages disease development.
2. Improve soil drainage and reduce compaction.
o Aerate the lawn regularly to create an environment less conducive to fungal growth.
3. Avoid watering the lawn in the evening or at night - prolonged moisture on the grass blades can promote disease.
4. Practice good sanitation by promptly removing grass clippings, fallen leaves, and other organic debris from the lawn to reduce fungal spore populations.
5. Select a disease-resistant grass variety if you are located within an area that is prone to favourable disease conditions (i.e. prolonged hot and humid weather).
6. Rotate fungicides with different modes of action to assist with prevention of the development of resistant fungal strains.
By implementing these preventive measures, you can minimise the risk of lawn diseases and maintain a healthy, resilient turf.
