Moss ?

There is Moss in my grass. Well, not my grass, but the grass in our kak rental. I don't think The Landlord cares about the Moss. Nonetheless, if we have to say here till June, somebody has to care about The Moss, and I guess that would be me. The Hubby, not so much. If it is green, it is just fine by him. So, at Asda, I bought weed and moss killer All well and good. The instructions tell me not to spread this stuff in conditions of drought, freezing, or imminent rain. Oh please. We apparently are in the middle of a drought, with a hosepipe ban, it is fecking freezing, and rains every day. What chance do I have? Also, the soil needs to be wet, but the grass dry, and 'actively growing' So, am thinking The Moss is here to stay.
