I think a caution is needed here.

Although the big bags of peat moss you buy in the garden centers are often marked to the effect "spagnum moss", these are NOT the type you want to use for bonsai.

What you want is the stringy stuff usually sold in smaller packages. You often see orchids planted in it. It is usually "blonde" in color. I have never seen the word "peat" on the package.
