Does anyone know whether or not coffee grounds are dangerous for the
health
of plants or lawn? I heard once that they are sometimes used when turf is
laid, but at my place there is a suggestion that some plants are in
declining health because I emptied the contents of the plunger on them!

used coffee grounds are fine on the lawn if sprinkled fairly thinly, don't
use as a mulch on lawn unless you want to kill it. There is some debate
about the acidity of used grounds. If that is a concern long term check the
ph of your soil and adjust it with lime as necessary. An occasional usage
isn't any problem. Same with coffee grounds on gardens. The odd plant may
not like it whereas I have found all my vegetables, shrubs and lawn do fine
with coffee grounds.
