I have a plant that was my mothers (who has passed away) And I am desperate to keep it alive. I had it at work and it was doing great. Then someone transplanted one of their plants with gnat infested soil. Which got into my plant. So I took it home and changed the soil and washed all the roots and now when the new leaves grow out they are curled and attached to ther stem they grow from then they die. And the other leaves are dying and falling off also. Pretty soon there wont be anything left of it. Does anybody have any idea what I can do.
