I think that I have watered it way too much over the last few months and that it got some kind of root rot. It started dying off from the bottom like 2 weeks ago. Today it broke off in the middle.
Does anyone have any idea how to save my little green friend? Or is it too late?
No, don’t water it for a while - if you do, it may rot! It’s got enough nutrients left in the leaves and stem to subsist for quite a while while it roots.
