Lawn problems
Why is my lawn brown? Diagnose it before treating it
Use the shape, timing and recent lawn care to distinguish drought, scalping, compaction, spills, pets and disease.
At a glance
- Map the shape of the damage.
- Recall weather and recent treatments.
- Check soil moisture and compaction.
- Inspect roots and leaf closely.
- Correct the cause before reseeding.
Pattern is your best clue
Uniform straw colour after weeks without rain is very different from sharp footprints, mower-width stripes or isolated circles. Look from an upstairs window and take dated photographs. Ask what happened one to three weeks before symptoms appeared.
Check irrigation overlap, spills, fertiliser routes, mower height, parked objects and pet habits. These clues often solve the problem without a treatment.
Drought or genuine death?
Dormant established grass may look dead but retain living crowns near the soil. Wait for sustained rain before assuming failure. Where soil remains dry beneath the surface or tree roots dominate, recovery can be slower and patchier.
If only raised bumps are brown, the mower may be scalping them. Raise the cut and level the surface during a suitable repair season.
When to investigate further
Rapidly expanding spots, coloured threads, rings, mould or turf that lifts unusually easily deserve closer identification. Avoid broad home remedies: the wrong chemical can worsen damage and affect wildlife. Use authoritative diagnostic guidance or a qualified turf professional.
Frequently asked questions
Should I water every brown lawn?
No. Established drought-dormant grass often recovers with rain; identify the cause first.
Why are there brown stripes after feeding?
Uneven or excessive fertiliser can scorch grass in regular application patterns.
