Question about very old Aspidistra
About 4 years ago I inherited an aspidistra from my grandparents when they moved. The plant originally belinged to my great-great grandmother, and is, by our best estimates, over a century old. Needless to say, I am terrified of killing such an amazing plant with so much history (if only it could talk...)
So far it looks like it's doing pretty well (knock on wood). It sends up a few new leaves every year, and the existing leaves are mostly a pretty dark green color.
My question is basically what I should be doing to take care of it? I've read that aspidistras are often hurt by over watering, so I give it a good soak only about every month, and my parents do the same while I'm at away at college, and I try to keep it's leaves free of dust.
Repotting seems like it would be an impossibility, so I think I'm stuck with the soil it has, though I layered a little new soil on top when I first got it.
I fertilize occassionally, and wonder what kind or fertilizer you'd suggest, and with what frequency?
thanks so much!
