I wish I could help with that Adeniunm Sophie but I've had absolutely no luck at all with these. I have three little ones that look horrible. Mine are outside but I think they got hit by cold this winter and maybe too wet. We are so humid here almost year round and I don't think they like it .. can't seem to keep them dry enough.
What kind of soil do you have it potted in? Maybe go with something much more light, loose and well draining with a lot of bark content? Or I wonder if they will grow in straight gravel? I bet once the weather warms and it gets lots of sun it will perk up.
