Both trees are in regular soil the previous owner uses successfully on thousands of trees he's got. Not defending the soil but it does drain better than other regular soils I've seen. The broken down fertilizer on it is giving it this swampy look but it's not muddy at all...
Here's a closeup of the soil without fertilizer.

And a picture of the cedrus Lebanus. Not the best bonsai but I love it. I might live in Lebanon but these are hard to find and very expensive as they are protected so am very worried about the first reply am about to do and not sure if I should change the soil 100 percent or leave some.
