Drip Irrigation lines are in

I  have  run flexible  black  poly  tubing  to   all  the planting  boxes  including the rain    gutters  which   were  installed   along  the   walls.  A  timer  initiates  a   slow   drip  which    in  the  gutters  leads  to  a  gentle cascade  of   water   from  high  to  low  containers.  With  an adequate  and  consistent  water  supply  these    wall  plantings   should  begin   to    thrive. Presently  they    contain  seedlings. Everything  in  the  garden   is  from   seed  and   is  still
maturing    but     by  the  time  school   starts  in   August  the  garden     should  be  full  of     flowers  and  vegetables.  Fingers  crossed. :)
