Any advise regarding the attached photographs would be much appreciated. The turf was laid in February this year and has gradually become more 'patchy'. I've watered and mown regularly and did feed at the beginning of April. Do you think the look of my lawn is 'normal' or do I have to worry? I also have the odd patch of clumpy grass as seen in the photograph labelled 'Thick Blade Grass'. Any idea what this is and why it is there? Many thanks!
