The soil in my raised bed is white and brown right under the surface. Is this a beneficial fungus? I've added quite a bit of compost to the beds, and they are filled at the bottom with wood and wood chips (kind of like a Hugelkultur bed).
It looks and smells good, but I had stunted plant growth in the bed last year. Many seedlings are barely able to grow. Could the reason be that decomposition is not complete?
Thanks for any help.
