What would work? No water, no nutrients. Black thick plastic weighted down

You'll have an empty place to 'start over' on. Till in good compost,

Um. Arrowhead (Sagittaria) is an aquatic plant.

I think the plant meant was arum, which has arrow shaped leaves & probably
called arrowheads in some localities. I love mine, but some people have
found them a terrible, terrible burden. Fancier mottled or dwarf
cultivars are slow to establish & not invasive, but the big wild form has
become a noxious weed in some places around the world.The only way to get
rid of it is dig it up, &amp never let the beautiful red seedheads
completely ripen, as after the seed-stock is ripe & falls over, insects
carry the seeds considerable distances, clean the fruit off it, & leave
the seed to start elsewhere. The big hood-flowers & the bright berry
stalks can be decorative for a long time in the garden, but before those
berries tip over & begin to mush up, they should be havested & thrown away
(not composted; they'll often survive the heat of composts).

It survives herbicides because it can spring back up strong as ever from
surviving fragments of its far-reaching stolons. One must either learn to
appreciate it for its very real beauty & late-winter ornamental strengths,
or dig it up to discard as religiously as one would do with perennial
morning glory or dandylions. Some things will frankly never be gotten rid
of entirely, & there are no shortcuts & absolute resolutions that won't do
a great deal more harm to all the rest of the garden than to an arum.
