Question
Hi, I have a China Doll thats getting too tall for it's living space, It's about 3-1/2 feet tall. I know about Pinching or pruning plants. But I don't exactly know how to do it. So my question is, What part of the plant am I Supposed to Pinch or Prune off? And will doing this make it more bushy, insted of tall?

Answer
Hi Ben
The best way to trim a plant is to make sure you trim at a leaf bracket.  This is where new growth will come from.  You can either 'pinch' or use scissors or pruners, whichever you find easier.  It will make the plant fuller.  
Good Luck Ben!
