I rescued this plant back in August, and I noticed recently that its younger leaves have begun to curl under. I don't believe the plant is necessarily sick, but I am under the impression I am not fulfilling its needs. It's about three meters from a tall window (I moved it to take the picture), though I believe it only receives direct sun for maybe one to two hours in the morning, at most. I also water it very sparingly, in relatively small quantities. On average it probably gets watered one to three times a month. Is it possible that I'm underwatering it? Would that cause the leaves to do this?
I also am curious about the shape of my plant. My kalanchoe has always been kind of stalky like this since I got it, and I was wondering if it is healthy for the plant to be like this. Most kalanchoe I've seen are a lot fuller, and shorter. Is it recommended that I do something about this as well? I don't mind it's appearance being tall and stalky, so long as the plant is ok.
Any opinions/suggestions are much appreciated. I don't have the best luck with succulents, so I'd like to do my best to look out for this little guy.
