I am wondering if any one has ever plugged an existing lawn with chamomile? Plenty of advise on the net about growing a chamomile lawn but can't see anything about doing this too. Many thanks.

Hi
You will be creating problems for your self if you mix the two as the grass will out grow the chamomile.
You could spray the lawn with a glyhposate to kill the grass off and then rake out as much as you can leave for two weeks any regrowth of grass do the same again then leave two weeks and then plant the chamomile as it will be safe to plant as glyhposate is inert once it touches the soil.
It will be interesting what others think but that's what I would do with the question you have asked
