g'day roga,

by containers do you mean pots with plants in them?

if so i would advise against having worms in potted plants, while they
may be some benefit they will disrupt the mix and their galleries will
not allow for any watering you do to soak into teh potting medium it
will run straight through.

snipped
With peace and brightest of blessings,

len & bev
