Hi there. I found this thread and now I feel even worse. I wasn't trying to save a dying cardboard palm, I HAD a thriving cardboard palm... And then I killed it. It was thriving but behind an arborvitae and hidden by a wall. Obviously I couldn't leave it there. So I moved it and divided the plant had 3 crowns. Put one into a pot and 2 separately into the ground. And then the yellowing happened and all the leaves dropped. It's over a year after it dropped all it's leaves. I haven't had the courage to throw it away, I am wishing it back to life. Or so I hope. I've moved it around to different areas of my garden and removed the one in the pot straight into the ground... To hopefully strike it lucky and grow again. Also it's just come into fashion again as I killed it and I'm not willing to cough up the hefty amount for another one just to end up being a serial cardboard killer. Any tips or tricks...
