Watering cans are not crucial to a gardener. You could water with a hose or an empty milk jug or any old container. But I believe watering cans are worthwhile not only for their beautiful forms and colors, but also for their functionality. I keep several watering cans my gardens, and I prefer the metal ones. There’s a certain Peter Rabbit charm to watering cans. Both decorative and utilitarian, metal watering cans add form and function to the garden.
Plus, watering cans are designed to water efficiently. The ones with long spouts can get inside a dense plant. You can’t do that effectively with a milk jug. Some watering cans have “roses”—attachments that screw on to the end of the spout so that water showers on a plant, much the way a gentle rain would do.
Two caveats about watering cans:
• I’ve read that some plants do not like to be watered from a copper can. This might have been bromeliads.
• If you accidentally drop a metal watering can on a hard surface, you might dent it or crack it so that it will not hold water. That happened to me twice, but I keep the old watering cans around for their shapes. Sometimes I tuck a container inside them and use them as vases for fresh or dried flowers or branches.
