The raised townhouse deck wicking bed. This bed improved on the prototype.
The frame of a previous wicking bed is reused for the new one. This picture shows the structure of the beds basic container.
The box is lined with building plastic. Place padding such as old rags or cloth between the wood and plastic. Also, between the the plastic and the gravel. This will protect the plastic from getting any holes in it. It is also a good idea to leave the plastic loose while filling the bed. This allow the plastic to adjust, and the bed to fill without stretching the plastic to the point of leaking.
Repurposed weeping tile was not available for this bed. Left over 4″ drain pipe is sturdy and easy to work with. Drill holes in either side of the pipe to make pathways for the water to escape evenly. It will work just fine. There is an option to wrap this pipe in a root barrier fabric as well. Known as a sock. This helps to keep the plant roots from plugging the pipe with roots.
The drain pipe is buried beneath the gravel. The fill pipe is on the opposite end of the bed as the drain. The fill pipe is attached to eavestrough on the deck above.
These pictures show the eavestrough and downspout. In the top left corner, by the bird house. Also, a space is left underneath for storage. Active children use this deck, so storage is needed.
The Finished Product
Down spout is finally connected and the exterior of the bed is painted. The bed is filled with soil, and the tomatoes planted.
The finished townhouse deck wicking bed project.
The finished product from a different angle. The wicking bed on the deck overflows into the lower garden. The lower garden is constructed in a wicking bed style as well. Although, not technically a “wicking bed”. See the Dogwood hedge page for more on that.
Active watering was stopped for the wicking bed in the middle of June. The last picture was taken August 27.
