You couldn't ask for an easier plant to grow, than a waterlily. They never need deadheading. They never need watering. They rarely need dividing or feeding and they bloom all summer. Unfortunately, unless you have a pond deep enough to keep them from becoming popsicles, you are going to need to give them some protection. Whether you'll need to dig them and bring them in depends on the type of waterlily, your USDA Zone and your garden. Here are some guidelines for keeping your expensive waterlily from becoming compost.
