This rock bed has grown into a mostly shaded area, so I decided to add more to the south (front) side. It will be filled with annuals and possibly a few perennials, including some hardy sempervivums. We have a surplus of wood at present, so I've used it as a base layer and added extra in the center to create planting pockets.
I added a base layer of weedy fill, tamped it down into the crevices and covered it with cardboard and paper.
Then I added nitrogen-rich homemade compost with blood meal and grass clippings to help combat any nitrogen depletion caused by the wood beginning to break down.
Next I added a blend formulated for annuals and watered it all in.
Finished except for weeding the old edges, adding plants and resetting the solar lights.
The shelf areas on the front and the two hollow top pieces are future homes for semps if all goes well.
Hugelkultur, or just another way to make use of some extra wood?
