Although Day lilies can multiply in the manner mentioned, it is not the only way you can multiply these wonderful plants. So why not cut them out and make more when they grow old and reproduce? It isn't as simple as that, but that is a rough summary of what you must do. The first step to take care of is observational in nature, take a look at the top of the stems that belong to the old flowers. Is there a formation of profiliferations? If there is, you have just found the little ones, and if they have roots extending from them you should cut the stalks about two to three inches below the new plants. Next you should remove about half of the foliage off of the new plants. Place those little nuggets of beauty into cups of water to allow the roots to grow just a tad bit more. Make sure to keep the water level even with the bottom of the plant. When they finally have healthy and matured roots, you can place them in pots filled with potting soil. Keep the soil moist and keep them in there for about a month before placing them into your garden.
