Can anyone please give me some advice, a few years ago I brought a potted plant consisting of an Afican voilet/palour palm and a peace lily. It became pot bound very quickly, so it is now on its third pot which is 12" wide and the palour palm is nearly 4ft high. I would like to split it into individual plants but am unsure how and when I should do it. At present there are no flowers on the violet. This plant sits on my upstairs window sill, but it is now taking all of the light away from the room.
