To focus on natural resources conservation, the eight wooden raised beds were made from materials that used to be shipping containers. The practice of using reclaimed materials in a garden space is part of reducing waste, an element involved in permaculture. Using harvested rainwater to feed the plants is also another way to conserve resources.
The garden also has two metal raised beds (similar to animal troughs) that were already part of the garden space before the wooden beds and rain barrels were added. When using metal planters with bottoms that are flush with the ground, be sure to drill some holes in the bottom to allow water to drain and soak into the ground. This helps prevent soil from becoming fungal from too much moisture.
