Training and trimming and managing a Scheffleria
I've a Scheffleria that is sprawling all over the plant room. From a single short trunk there four branches that spread out six feet across and three feet tall **. It is quite healthy but not symmetrical or otherwise traditionally lovely. I need to do some serious tree surgery and Scheffleria management. I should like to cause it to grow taller and not so widespread. I would eventually like to see something closer to six feet tall and three feet across.
Do I chop it back drastically? Do I chop it back a bit from time to time? Do I try to prop the longest branch upright and cut the others back drastically or a bit from time to time?
**[As usual I exaggerate. I just went and measured it. It is only 69 inches horizontally and 27 inches tall. ]
