Hi Ed,
to NGA
I think most of us haven't answered because there are way too many questions:
Is this an indoor or outdoor plant?
If it spends any time outdoors or near open doors or windows, where do you live?
How long since you have repotted? What kind of soil is it in?
Are the leaves soft or hard? Have you noticed any soft spots on the stem near the soil line?
How much sun does your plant get? Have you moved it recently? Changed how you care for it?
Can you back up and take photos of the entire plant including the pot?
How long have you owned it?
Anything else you care to share that might help us help you?
