Waterlilies are usually perennials meaning they will die back to their roots during the winter and grow again in the spring. We stop fertilizing our lilies in October to prepare them for dormancy. Remember fertilizer stimulates new growth and by October lilies need to start their natural cycle of preparing for winter. The leaves will begin to get smaller and not grow as rapidly until you have no leaves/blooms left just a pot of dirt. Don’t panic the tuber is in the soil staying warm at the bottom of the pond conserving it’s energy till we start to warm up in March. Now if we have an abnormally cold winter with multiple freezes your waterlily may not make it and there isn’t anything you can do to save it. You will know by March if the temperature is on a good warming trend if the lily made it through the winter, the plant will start sending up tiny leaves and this is your cue to repot. Repotting should only be done in the spring and we will have instruction on how to repot your lily on your own this coming spring. In the meantime if you are looking for some greenery to cover for your dormant lily try out a water hawthorne. This is an aquatic winter annual perfect for adding a bit of color and protection for your fish from predators during the “long” winter months.
