When we took on Mr RB’s lawn he was almost at the stage of re-turfing it as it had become so thick with thatch and moss that the healthy grass was actually rooting above the soil in the thatch.  His lawn was in danger and what followed was a course of extensive treatments both mechanical and seasonal fertilisers.  It wasn’t easy but a year later we had the results you can see here. Please note the before and after shots of the bare patches that were present all over the lawn.
