Hi,

I've just returned from 2 weeks holiday and discovered a big brown
patch in my lawn. I'd say it is about 2 foot square. It's been
raining a lot in the UK recently and the soil below the grass doesn't
feel dry but the grass itself is brown and curled up.

Picture attached.

Any help appreciated.


My first guess would be a chemical or gas spill, or maybe a heavy dose of dog
urine. Or, something dark got left there and heated in the sun.
