Someone asked a question on what woods not to use, so I'm wondering why you shouldn't use these wood types when building a hugelkultur (raised bed used to either conserve water, or increase surface area on top of rotting wood):

  • cedar
  • camphor wood
  • black locust
  • black cherry
  • black walnut
  • pine
  • fir
black thumb

The types of wood that you have mentioned contain tannins that negatively affect the germination and the growth of the plants, nitrogen availability and photosynthesis. They are also toxic for some microorganisms.
