Lawn in a bad way! Help!
Around 4 weeks ago now, I tried to repair my already patchy garden lawn with the Westlands 'All in One' lawn treatment. Despite efforts to use the right amounts, i must have used far too much and 'burned' the lawn. I had huge patches of black areas and it looked terrible. 4 weeks on, i've left the lawn to recover and gave it a trim yesterday (results in the picture attached). Some small areas have taken the treatment and look relatively healthy, however most of it is still very patchy, brown and dead looking:
What is the best approach to get this looking nice? The garden isn't huge, and i want to extend the lawn areas left and right to create more width. Is there a cheap fix to recover the lawn or will it need re-laying? If it does need re-laying, how much would a job like this cost?
Any help would be great! Thanks
