Can the Subpod be used in a wicking garden bed? How much depth of soil do you need under the pod? I'm intending to get a wicking bed (Timber framed) built next month but they recommend only about 350mm of soil depth over the water cells so the wicking is able to reach the roots of shallow rooting
We have not tried Subpod in a wicking garden bed, but we will be trialing some in the future.
We believe, Subpods are a natural fit with wicking beds. The portion of the Subpod that is buried below the surface is only 320 mm and the rest is above ground, so the Subpod will easily fit in the soil above the wicking part of your wicking bed system.
Because the Subpod allows the composting worms to freely move through the garden bed, they will play an important role in keeping the soil of your wicking bed well aerated to help maintain its wicking ability.
You are welcome to try this and be a pioneer for Subpod. We have a Subpod prototype installed at Spell and The Gypsy: https://subpod.com/pages/spell which is not a wicking bed but a closed garden bed. It is working well so far, but we are still gathering the results.
We would love to hear how you with your wicking bed if you decide to get a Subpod and install it.
