Question
My Draecaena crown is weighing the plant as a whole down because it is too big. Can I cut the crown back and salvage what I cutback to prevent it from weighing the entire plant down?

Answer
Hello! This is a great question! Dracaena's are a diverse genus of plants, but nearly all can be renewed or propagated in the same way.  First, try thinning out the crown some. Has it ever flowered for you?  If not, you'll be in for a treat: many 'corn plants' have lovely scented blooms.  
 But, yes, you can cut the crown back to within a few inches of the soil line and actually use some short cuttings to start new plants.  Here's how:  First, if your plant has any offshoots, escpecially near its base, gently cut them away from the mother plant with a sharp knife.  Then, put them in a pot with good drainage and moist - but never soggy - soil. These little ones usually root quite easily.  
  For the larger main trunks, cut them within a few inches of the soil line. It will renew itself. For the trunk cuttings, cut them into 3 to 5 in. sections and place them into a well-draining, pot of moist-but never soggy- potting soil. These will easily root also. With pencil-thin, or so, width canes, you can often put them horizontally into moist soil and they'll strike roots from thier nodes.
Thank you again for your question and if you've any further questions, do feel free to write! Best of luch!
