I've joined this forum to ask this question, as we have made a huge mistake. We bought some evergreen 4 in 1, but were very naive and put too much on the lawn, leaving lots of black marks and holes. Considering the lawn was pretty much all weeds, it's a wonder it doesn't look worse.
Here is a picture of the lawn as it stands now:
Pretty bad huh? Just wondering what we can do to fix this, and hoping the blackness will not be permanent. I know grass can grow under the worst conditions, so we're hoping in time it will go back to normal colour.
Any advise in the meantime would be very helpful.
