soil layers.
Natural soil occurs in "horizons", but this layering occurs because of
a combination of weathering, microbial activity, and most especially, the action of water on a large horizontal surface. Phenomena such as "perching" have meaning when you are talking about a surface area of acres; it has NO meaning in a bonsai pot with a surface area of square inches interrupted in each direction by the SIDE OF A POT. There is no need to worry about soil structure in a bonsai pot as long as the soil is well-draining and the pot has good drainage holes. Nina. |

This is (to me) a perfect perched water table.

Thanks for your post. I print out a hard copy of almost everything you write - does that get me in your fan club?

The only time I have seen evidence of perching is when I do an emergency repot in the middle of summer because the plant is stressed and the roots on the bottom of the pot are no longer healthy. That lower root layer seems to be a barrier for new roots to move through. A couple of years later and that layer if roots is still not penetrated.
I have used and not used layers. I have never created a layer where the roots do not penetrate. Kits **** "Expectations are resentments under construction."
