When planting new plants in a pot. I line the pot, perforated or not, with
landscape "cloth". The fiber glass kind. Then pack the plant with
purchased "topsoil" which is almost always clay. My Koi turn anything over,
they can. I usually place the new pot in a MUCH larger one and fill the
space inbetween with 1" pebbles.
