There are basic types of watering cans, plastic or metal. There are hundreds of styles, colors, sizes and nozzle options. Plastic cans can be lighter than metal, but won’t last as long. Metal cans should be galvanized to resist rusting. Consider the size of the can relative to your strength. The handle position should allow you to carry a full can and also tip it to pour easily. Two-handled designs allow for better stability for children or elderly gardeners. You may need one with a sprinkler head for outdoors, and a smaller, long-necked version for houseplants. For outdoor use, Watering Can with a dual-handle design and removable sprinkle nozzle.
