I've had this one for about 3-4 years - found a piece of if on the ground broken off from the big plant and potted it, and it kept growing since (in the same pot all this time). Few days ago, one of the branches just snapped off from the base, and now it seems like another one is slouching and will snap off too. It's a bit yellow down at the base. Otherwise it looks very healthy, and other branches look fine too.
I think here isn't enough light for them where I live, but it kept growing all this time so I have no idea what the problem is.
