I recently due over my entire garden and seeded a new lawn. For the first 3 months or so it looked lovely, lush and green all over. In the last couple of weeks part of the lawn looks yellow and is not growing very much at all. The are that is now yellow is the area that was not grass in the garden before I dug it over. The area where the old lawn was is still lovely and green. Have a look at this photo to see what I mean. The area to the top left is the area of concern.
What can I do about this please?
