Hi,
Recently I have repot one of my bonsai(banyan tree) and after two weeks the leaves are becoming dry and yellow without any reason. The same soil I have used for my other two bonsai also and they are still fine. I have check the soil, the soil is not damp. It is ok I think. Can you plz give any idea that how can I overcome this?

One more question,
I have seen most of the bonsai image that have a green moss type in the soil surface. What is this? How I can make this ?
