where the water outlets down the side of the planter.

Just insert an appropriate sized rubber hose from the hole
in the side to the adjacent ground area. Auto parts stores
often stock a wide variety of rubber hose sizes, sold by the
foot. Not likely to leak since little pressure build-up.
Also easy to remove to clean the hose and poke into the hole
to ensure it is not clogged.
