Q.rootbound plant
If a plant is root bound, do I cut some roots when transplanting? The plant is a very large purple passion in a 6 in. pot and has branches from 2 ft. to 10 ft. long. It is so beautiful but seriously root bound. And can I cut some of the branches off and use for starters at same time?
If a plant is rootbound you have these options: re-pot in a bigger container, prune the roots and re-pot in the same container or divide the plant, if appropriate.
And, yes, you may take stem cuttings and root them to propagate your plant.
These articles will explain those options in more detail:
