I live in Florida (Tampa) and have two cardboard zamias, that despite my efforts received frostbite. They are now a beautiful shade of bronze, but I know that's bad news for the future. They are large (4' in circumference), and I don't know what to begin doing to save them or if it's even possible.
I am sorry to hear about your plants. This article may help you with getting them to recover: https://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm
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.
I have an indoor cardboard palm that hasn't gotten a leaf in two years. They come out (much slower than the past ones) and turn brown, or they start to leaf out and turn brown. I've tried more water, less water, more fertilizer, less fertilizer but it doesn't seem to help. The fronds are not forming like they should. I live in PA. Help me! Thank you.
You mentioned watering schedules and fertilizer, but what kind of lighting is it in most of the day? Cardboard palms thrive in moderate to bright light.
Also, what type of fertilizer did you use? You should fertilize with a slow release palm food or a diluted household plant food once monthly during the growing season
Lastly, is it possible the cardboard palm is root bound? That would stress the plant and cause erratic growth and problems. I'd take a look at the roots and see if something's amiss. You might give it a new pot with fresh potting soil and add some extra perlite to facilitate drainage.

Thank you for the answer, Shelley! Exactly, then I added a new soil as much as possible and used Palmgain fertilizer, it was helpful. And also as said above it often depends on right fertilizer.
I want to split my cardboard palm into 3 separate plants, as it has 3 heads which are all joined together. Is this possible? It is about 4 years old and growing well and the plant is healthy it is housed in a pot.
No you should not try to separate the plant in this manner. I believe your referring to the male and female cones that have formed.
Propagation by seed is the best way to grow more plants.
What is the pine shaped cone that grows out of the cardboard plant?
The cardboard plant, botanical name Zamia furfuracea, is a member of the cycad order, an ancient order in the plant kingdom. It is related to sago palms. The cone that you see in the center is the seedpod of the plant. Like most cycads, it looks something like a pine cone.
Our cardboard palms appear to be a little pale (light green} Is there anything we can put on them to "green" them up?
This article will refresh you on the care needed.
We have 2 plants in our front yard. They are beautiful. My problem is that they are growing so large and spreading out. I have no idea how to prune these and do not want to lose them. Any help would be appreciated. Thank you, Joyce Dickinson
A late winter rejuvenation pruning is often needed to remove dead or declining leaves and to reshape the plants. Out of bounds shoots can be removed during warmer months.
