I had a lawn just like yours last season - I used this during the Autumn/Spring http://tiny.cc/5FJ31 to cleanse and feed the lawn. I then raked out all the dead stuff, left the lawn to rest in growth until the grass was 4" long, cut it right back as short as I could, seeded and then....

These are the products golf, cricket, football, bowling etc., greensmen use.

You will see such a lush green lawn and you will get a fantastic show of flowers and growth in your garden especially when you feed with: http://tiny.cc/CiJ1S.
