How to divide old Cymbidiums?

[Cym Ladye]

Shiffdaddy,

Thanks for the input on this. I have always used an expanded perlite in the form of #3 or #4 Sponge Rok for just the reasons you stated. I also use a couple of other inert ingredients, which do not break down either, but that would be giving away all my secrets and not really needed for the basic mixes I tend to recommend.

One point on the "safe to handle" statement. This is one product you do not want to inhale as it can definitely irritate the lungs! To avoid the dust I wear a mask and wet it before adding it to my mix .
