WHAT HAVE I DONE???

Now to go into detail.
After removing the soil and the straggly roots, I could see that the cutting had been shoved into the 150mm pot to grow on by a wholesale production line with little regard for root structure and much regard for keeping ones job

Most of the roots were growing in an upright direction (hence my deductions on the plant being shoved into the pot) so I decided that they had to go including the large one travelling down like a snake.
As the plant cost me all of a cup of coffee like the scissors, it matters little if it is set back or dies. Personally I hope it picks up and keeps on.
With any luck the rock will do its job as a spreader and what roots that are left will gain some bulk over the net 12 months.
I have put it back into the pot on an angle to get it started on for its next visit to the doctor.
Although it is not shown in the pics, I did give the top a cut back, I won't do any more with it apart from watering and feeding until around this time next year.
Comments, slaps on the wrist and guidance are welcome as always.
