Dear all, Our soil is clay and so, coupled with the Scottish weather, is often sodden with water. After a very wet autumn and winter, (even by our own standards), large patches of moss have appeared on the front lawn. The back lawn isn't nearly as bad with moss - probably because the front forms a basin, sloping down towards the house, whereas the back slopes down to the house behind us and so drains into there (!). A couple of weeks ago, I did the first cut of the year and then put down some evergreen lawn feed and moss killer. This was in advance of me intending to scarify to remove moss and thatch (the 3.5 yr old lawns have never been scarified). However, I've noticed that not all the front moss has turned black indicating its not all dead. I applied the evergreen using their own spreader at the recommended setting. There seems to be black lines running through the moss, indicating where the evergreen granules were landing. Questions: 1) Should I progress to scarify, even though not all the moss is black? Ive read that scarifying live moss can just spread the problem about. (I thought about putting more evergreen down, but the instructions say only 1 application every 3 months.) Or would it be better to wait and scarify in autumn instead, allowing for a further application of the evergreen first? 2) Ive heard warnings about scarifying on slopes. There are slopes on both our lawns. Should I just strafe left/right across the lawn, rather than go up/down the slopes? 3) What would be appropriate machine setting for the first scarification of these lawns? Everyone says to be prepared to be shocked at the amount of rubbish that the scarifier will lift, equally I have heard warnings to "go easy" so as to avoid ripping up the entire lawns. Thanks for reading and for any advice.
