Q.How Do I Separate My Cardboard Palm?
My cardboard palm is very old, more than 20 yrs in the same big pot. It is so crowded with pups that it has stunted the way it normally looks. The root system is HUGE, like it needs a saw to cut it apart! I am afraid to transplant it for fear I will kill the plant. What do I do. . . saw them apart from each other or not?

I've never divided a cycad. When I divide any plant, I use either a sharp knife or saw. This sounds harsh, but actually does less damage than trying to wiggle them apart.
