Step 4: Watering system

Picture of Watering system
There are 2 major ways of watering the vertical planter. 

- One, as I used, is to insert a drip irrigation pipeline (as shown in photo) from the top or the bottom (depending on your needs) into the pipe. 

- The second way, if you have sparse soil, simply water from the top part and let it trickle down to the bottom.
