I went to look at a job earlier were a customer was complaining that

The question he asked was how he would get rid of it from the lawn
and
it had both me and my dad stumped as i didn't think a normal
selective
lawn weedkiller would do the trick because of the type of plant and
even
if the lawn was the be replaced with new turf then there would still
be
the problem of the seeds germinating in the soil.

any suggestions on either how to get rid of it or how to manage the
spread of the plant.

we have already told him to remove the parent plant that the seed is
coming from in his garden but his neighbor has the acorus growing
around
his pond and doesn't want to get rid of it so the seeds will still
come
from there

any suggestions will be much appreciated
Interesting. Wikipedia suggests that the cultivated form of A calamus
is triploid and sterile. If this is indeed what is being grown, then
it
isn't coming from seed, its spreading from rhizomes. In which case a
bid of glyphosate carefully applied might do the trick.

IIRC, I've read that the diploid and triploid forms are about equally
common "in the wild" in the UK.
