At our last Permabee we constructed a new wicking bed for some Perennial vegetables and espaliered fruit trees. We made the slightly raised garden using small children’s wading pools for the water reservoir, blue metal gravel, wicking material, soil and of course mulch. We sunk the pools below level of the garden, filled them with gravel and covered them with the wick that covered also the whole garden. We then filled the garden with soil and compost. We then fertilized, mulched and planted. Here’s a couple of pics of the process.
Before/During/After and NOW the garden planted, proud & already productive
