Most fish pests die after a week without a host, so a week in a bucket
of water with a good lot of soil for fertility gives you plenty of
time to think about potting them up.

While in isolation as simple as that you get time to look for
beneficial things that might be hitchhiking, there can be tadpoles, of
newts, frogs toads... some snails like ramshorns , beneficial insects
like daphnia, crustaceans such as freshwater shrimp and gammarus, any
of which could be worth putting in an aquarium to establish in the
pond after cultivating them in an isolation positon

After a weeks isolation, lifting the plants, shaking any loose stuff
off, then a dunk in a bucket of water with two spoons of domestic
bleach for several hours, will kill any fish pests and if you are
LUCKY, might kill a fungus such as lily root rot, and highly
destructive tropical pests such as nematodes that cause problems in
Florida and Hawaii

Pottasium permanganate will not destroy those.

When purchasing new plants do you treat them first before placing them
in your pond? Can pennyworth be submerged and if so how deep? Thanks
