Our front lawn is in an awful state. There are weeds, clover and moss and the soil has compacted over the years. It desperately needs attention. We have been advised that we need to use a weedkiller, iron to kill the moss, scarifying, fertiliser at regular intervals and new seed. We don't want to use anything that would harm the insects or birds, and wonder if anyone has treated their lawn in this way and which products they would recommend.
