Answer
Hi Bob,
Thanx for your question.  I won't laugh.  ;o)  Next year, when your mums begin to grow again, allow them to grow about 8 or 10 inches tall and then cut them back to 4-6 inches.  Take the cuttings and stick them in the soil and keep them watered but not soggy.  Many of the cuttings will easily root this way.  Most people trim mums back until around the 4th of July.  Not only will this keep your mums in a nice compact shape but you can make more plants with the cuttings.  I hope this helps.
Tom
