Expert Reveals Instant Solutions for Reviving Brown Lawn Patches

As summer approaches its end, many homeowners are left grappling with discoloured patches on their lawns. These brown spots can signal underlying issues that require immediate attention. According to horticultural expert Phil Catron, president and founder of NaturaLawn of America, various factors contribute to this lawn distress, particularly during the transition from summer to autumn.

Understanding the Causes of Lawn Damage

During the summer months, both drought conditions and excessive moisture can lead to significant grass damage. Catron highlighted that the combination of “warm, humid weather” often paves the way for fungal infections, which manifest as unsightly brown patches on lawns. He shared insights with Martha Stewart on three common diseases that affect turf.

The first, known as brown patch disease, creates irregular areas of discoloured grass that become apparent when the turf is waterlogged. Another issue, summer patch, manifests as sparse grass that turns yellow before deteriorating to a brown hue. Pythium blight, also referred to as “grease spot” or “cottony blight,” presents sunken, brown zones on lawns, often accompanied by a slimy coating on grass stems.

Effective Treatment Strategies

Addressing these issues requires a tailored approach, as there is no one-size-fits-all solution. Catron emphasized the importance of improving air circulation and soil drainage as critical first steps. He cautioned against excessive fertilisation, which can exacerbate problems, and encouraged the use of fungicides after consulting with a local gardening specialist to identify the specific type of fungus present.

“Keep an eye on lawn conditions and be proactive about addressing any signs of disease to minimise damage and improve recovery chances,” Catron advised. Quick intervention is essential; untreated fungal infections can lead to permanent grass loss.

Repairing Lawn Damage

In cases where brown patches are identified as fungal, immediate action is paramount. The Royal Horticultural Society (RHS) recommends treating diseased areas with fungicides and then reseeding or patching them. Homeowners can use turf from other parts of their lawn or, if available, fresh turf for repairs. The RHS noted, “The latter gives instant results, but sowing seed may be easier and cheaper if you have no spare turf to use as a patch.”

Alternative Causes of Brown Patches

While fungal infections are a primary concern, other factors can also lead to brown patches. Lucie Bradley, a gardening expert from Easy Garden Irrigation, pointed out that pet urine can severely damage grass due to its high nitrogen content. “While it can act as a fertiliser in small amounts, it can burn when concentrated, creating dead patches on the lawn,” Bradley explained.

Although reseeding and patching are effective solutions for areas affected by pet urine, homeowners may need to be vigilant in monitoring their pets to prevent further damage.

In conclusion, maintaining a healthy lawn requires ongoing attention and care, especially as the seasons change. By understanding the causes of brown patches and implementing swift treatment strategies, homeowners can restore their lawns to a vibrant and healthy state.
