Dracaena problems - help please
I just inherited a Dracaena (fragrans, I think) plant from a friend & it seems to be in a pretty bad shape. I'm not sure what to do...
Virtually all of the leaves on the plant are browning & I plucked off couple dozen completely dried up leaves when I first brought it home couple days ago. Is this fluoride toxicity? Seems pretty extreme. The browning looks like it's starting from the sides of the leaves then spreads towards the center/whole leaf.
The trunks are all very firm & I don't think there is root rot (didn't smell anything and they're not brown & slimy), although it is definitely pot bound with a bunch of roots sticking out of the bottom. Maybe an insect infestation of some sort or a fungus?
The only other thing I'm thinking is it's because of exposure to the cold. It was 15 degrees when the plant was being transported, but it was outside for less than a minute & inside a van for ~half hour, which wasn't that cold (plus, there were already a ton of brown & dried up leaves).
Any thoughts as to what's wrong with it? What should I do? I'd very much like to nurse it back to health, if possible... Should I change the soil & repot it?
