Self-watering square planters use an inner bucket and reservoir to keep roots supplied between refills, so flowers and foliage need less frequent attention. Each planter stands 22.5-in tall to add height on decks, balconies or in living rooms while keeping a compact footprint. The removable inner bucket simplifies planting and cleanup and includes hidden handles for easier lifting. Over 100 drainage holes plus a pre-marked bottom hole help manage excess water in changing weather.
