Why Your Lawn Has Brown Patches and How to Fix Them

Brown patches on your lawn can be frustrating and unsightly. Whether they appear suddenly or develop over time, understanding the causes is the first step toward restoring your yard to its full green potential. In Fort Wayne and Northeast Indiana, several common factors contribute to brown patches in residential lawns.

Common Causes of Brown Patches

Brown patch disease is a fungal infection that thrives in hot, humid conditions and is one of the most frequent culprits. It typically appears as circular patches of discolored turf, often with a darker ring around the edges. Other causes include drought stress, where insufficient watering leaves grass unable to sustain itself during summer heat. Grub damage is another possibility, as these lawn-destroying insects feed on grass roots below the surface, causing sections of turf to die and pull up easily.

Diagnosing the Problem

To determine the cause of your brown patches, start by examining the affected area closely. If the grass pulls up easily like a carpet, grubs are likely the issue. If the brown areas have a ring pattern and appear during warm, humid weather, fungal disease is probable. Irregular brown patches during dry spells usually indicate watering problems. A soil test can also reveal nutrient deficiencies that may be contributing to discoloration.

Treatment and Recovery

For fungal brown patch, apply a fungicide and adjust your watering schedule to water early in the morning, allowing grass blades to dry before nightfall. For drought-related browning, increase watering depth and frequency, aiming for one inch of water per week. If grubs are the problem, apply a grub control product in late summer or early fall when larvae are most vulnerable. In all cases, overseeding the damaged areas with quality grass seed and keeping foot traffic to a minimum will help recovery.
