It is a sad thing when gardening involves toxic sprays to maintain a green desert. Why not invite clover, yarrow, self-heal into the lawn? It looks fabulous. Daisies are pretty too.
@glasgowdan why should I keep my opinions to myself? I like to share them. Especially when it comes to reducing the amount of toxic spray let loose on the world. There is no rule that a question is only allowed to be answered in a narrowly defined way. Anyway, my help consisted of pointing out that the concept of 'lawn' can have a solution that is different from a green desert requiring toxic sprays, a solution that is pretty and additinally beneficial to wildlife rather than harmful.
