I was wondering if you could give me some advice about my lawn. I laid it 2 years ago with turf, but my garden gets very water logged in the winter, and doesn't get much sunlight so doesn't dry out very quick, the result being a lot of bald patches, especially around the edges which are sloping and along the path which the water runs off of onto the grass. To try and resolve the problem I have laid a border of chipping all around the edge hoping that the water will drain away there. what would be the best thing to do now to get the grass back to looking like it did when we first laid the turfs, should I overseed it or would it be best to re-turf it? Any advice would be very much appreciated.
