The pot-in-pot, in-ground system
involves sinking an outer or sleeve pot into the
ground and inserting a second pot, which is the production
pot that is harvested with the plant. The
production container may have vertical ribs, or the interior walls are treated with copper to reduce root
circling. The in-ground container system is a single
container (unlike the pot-in-pot system) with rows
of small holes along the container sides and bottom
to enhance drainage.
