Brown patch lawn disease is a common fungal condition that affects grass, particularly during warm, humid weather. In the UK, it is most often seen in late summer but can also appear in mild, damp periods when temperatures remain high overnight. The disease is caused by the fungus Rhizoctonia solani, which thrives in moisture-rich conditions.
What are the symptoms?
The obvious symptom of brown patch is the appearance of areas of brown, thinning grass. These patches can range from a few centimetres to several metres wide. In early stages, affected grass may look water-soaked or dark green before turning straw-coloured. In humid conditions, a smoky or grey ring may be visible around the edge of the patch in the early morning. Knowing how to spot it means you can address it.
Brown patch commonly affects lawns that are overwatered or overfed
It particularly affects those with high nitrogen levels. Poor drainage, compacted soil, and cutting grass too short can also increase the risk.
Tratment focuses on improving lawn care
Reducing watering frequency, especially in the evening, helps limit the moisture on the grass surface. Avoiding excessive nitrogen fertiliser during warm weather is also important. Improving air circulation, relieving soil compaction, and raising mowing height can help the lawn recover. Investing in regular grounds maintenance Gloucester can reduce long-term landscaping costs.

Fungicides approved for UK use may be necessary
They are usually considered a last resort. With good maintenance and care, most lawns can recover from brown patch and return to growth.
