Wicking beds

What is a Wicking Bed?

Wicking beds are a method of gardening where the plant bed has its own “reservoir” of water under itself.  This is obtained by placing some form of waterproof barrier under the bed, and filling it with a specified material layering that promotes the soil’s natural tendency to wick moisture up.

You can see this in nature along river banks and waterways.  The soil above the water level, up to about a maximum of a foot is wet.  We are just taking that physical property of soil and using it in our gardens.

Generally, wicking beds are raised beds, but not always.  I have built a Dogwood hedge using this method.
