I have had a bonsai for about 6-7 years now...you will notice from the photos that I felt bad to trim it so even though I still call it a bonsai, its all overgrown. I believe the type is Zamia furfuracea. I have not changed the way it is being watered, or anything in fact, and suddenly the leaves from the original branches are drying up and cracking off. I am frantic over my bonsai potentially biting the dust. The only thing I can think of is that perhaps it is rootbound in the pot its in and I need to re-plant it in something larger so the roots can sustain it. Has anyone ever seen this before, and have any recommendations? Thanks so much.
