Hello, I'm new to gardening and need some advice please. Had my lawn laid 4 months now, good quality top soil 100mm. Told not the cut the glass for a month, by the month came it was 9inch in length. Since cutting it down in stages and to (not shocking the grass) I've noticed bold patches and grass looking like it dying in patches. I watered morning and night for the fist 3 weeks then evening for 30mins, since the hot weather we are having now, I don't know if I'm watering to much at night and still a bit damp in the morning, and the sun is scorching the grass. Never used to like my garden but since having a revamp it like my baby. I've spent a lot of money and any advice would be greatly appreciated. Also what feed can I give my lawn Being so young.
