Nyboy, When it gets too tall and lanky over the winter you should carefully cut each stem in half. Then you can take those clippings, strip the leaves except the few on the top and dip them in rooting hormone, or dissolved aspirin, then stick them in potting soil in a pot. Water well and set the pot in a zip lock baggie. You will have lots of babies to use for next summer or to give to all your friends or sell them at a plant sale.
