Most plant containers come with a saucer or a tray to catch excess water and keep it from spilling out onto floors. This is especially important for indoor plants where water can damage carpet and wood flooring. It is best to keep a saucer or a tray under a plant container for this reason, but even this may not be enough to prevent other types of floor damage. Consider placing a cork pad under your plant container to prevent your floors from being scratched. A cork pad can also alleviate the worry that a water saucer or tray might sweat onto a floor.
