I have two China dolls that are about 3 years old. They are about 5 feet tall and still in the same pots in which I purchased them. They are getting too tall and too wide for their indoor location and I have not been able to find any instructions for pruning them to keep them to the size I want. Will pruning damage the plants? Your website does not recommend repotting but what about transplanting them to an outdoor location?

Pruning can be done at any time. A healthy stem can be cut back to any point on that stem. The new growth will emerge just below the point of the pruning cut, so prune back to the place where you want new growth to come in. If your plant is healthy and you are able to keep the soil properly moist, then there is no benefit to repotting or replacing soil. If you live in an area where cold winters are not a problem, then it can be transplanted outdoors. They can not survive winter outdoors.
