I was recently given this indoor tree. It is in quite bad condition and I would like to revive it if possible. I am not sure of the variety, but after searching the web I think it may be a mass cane. Please correct me if not. The leaves are very long. All of the leaves are dark and unhealthy looking; many exhibit significant discoloration as visible in the photos. It was not until closer inspection that I even realized some of the leaves were variegated. The youngest ones at the top of the cane-heads are soft, translucent. The leaves are wrinkly but not brittle. All of three of the tops of the cane-heads are soft, soggy, and drooping. The plant has clearly been distressed for some time. Older leaves towards the bottom have dry, brown tips. The top layer of soil appears to have some form of mildew. On a positive note, I felt along the cane from the bottom up, and the original cane and the other (sub?)canes appear to be solid right up until the top 3-4 inches of growth. I do not mind chopping as much of it down as necessary to help it recover, but I require advice about how to best prune it, and how to ensure that the mildew problem is vanquished. Any suggestions about what likely happened to it, and how to best avoid the same issues in the future would be much appreciated.
