I've got a small patch of lawn (rented ground floor flat). The grass was overgrown and now lots of dead patches since it has been mown regularly. I love the idea of a camomile lawn or similar alternative e.g. creeping thyme, though preferably lowish pollen. Could I plant camomile/thyme in between the healthy patches? Should I replace the whole lawn with camomile? I'd love to hear about anyone's lawn alternatives.
