I have this reaper plant that was started over the summer in a qt size pot, by the fall it needed a larger size so I transfered it to a bit of a larger pot but not 5 gal. The roots were taking up the whole pot when it was moved and I did not disturb them at all so when it got into this bigger pot it grew more on the top, it's now top heavy and falling over, can I trim the top off and not hurt the plant? I do have 2 other plants which are doing very well indoors so I won't be without a plant. Any suggestions?
