This living plant wall is actually 2 freestanding, self contained cabinets that are placed side by side, to give the illusion of one large wall.

Anatomy of a Living Wall

Since live plant walls seem to be the latest rage, I thought it might be helpful to actually break one down a bit and show how the whole thing works.

It’s a pretty simple but ingenious system. The plants rest on long trays with a divot at the bottom, and the pots fit snugly in these divots to keep them in place. As water gets pumped from a resevoir below, it cascades through each tray until that tray is filled, then it moves to the next tray down. The bottom tray feeds directly back into the resevoir stowed out of site in the cabinet below.

This way the plants always have enough water without actually having their roots get rot by constantly being inundated. You can even put the pump on a timer so that it comes on at the needed watering interval. This will depend greatly on where the wall is placed, how dry the room is, etc.

4 inch plant sizes

These walls are comprised of over a hundred 4″ plants each. Each of these plants sits in it’s own tray within the wall itself. The plants are deliberately placed close together to make it look like one big planting.

The plants rest in these individual divots in long trays that span the length of the wall. The divot holds water pumped up from a resevoir at the bottom of the wall structure that feeds into the top tray. Each tray is interconnected with plastic tubing and the water cascades down to to each tray, filling it to a certain point before it overflows to the next. This keeps the plants from having their roots constantly wet. The bottom tray simply drains out into the resevoir, so the whole process can start over again.
