I had mine in the garage in the dark and they slowly grew very pale leaves. I moved them under lights and they started to develop chlorophyl and turn green. Now they are full and robust. I didn't think about cutting them back as they had growth. So if yours have growth and it looks healthy, you could cut a few back and let the others grow as Arlene suggests. A good experiment to see if the ones cut back are more robust that the others. Should be interesting. Be sure and let us know.
