large paph division

[jmateosky]

Hi,

I have several paph that are getting kind of large now. when I divide them how to divide them. The number 3 keeps pooping up cymbidiums and Catleyas people say 3 bulb minimum when divivding. does this apply to paphs as well?

Also when you divide there is a tough "woody" root when you cut them how do you "cure" it some have said with paint or special sealer?

Thanks,
Jim
