Ursula, I agree that Debbie is a beauty! I can relate to the problem with dividing it, as I just went through the same thing with my Gerberara. I finally took a bread knife and just sawed through it, dusted the cuts with cinnamon, and repotted. The two largest divisions will still be a big ball. There is just no way to spread the roots when it gets that bad, but I did get one smaller piece too. All are putting out new growth, and spikes.
Elaine, That's a pretty Epi. You do know that it will get huge, right? I have two that I need to repot soon, and I'm not looking forward to the job.
