An indoor watering can should put water at the soil, not on the leaves and not in a crater in the pot.
We watered houseplants with long-spout cans in copper and coated steel, full and half full, watching balance and whether the stream dug a hole.
Reach and balance
A long spout lets you reach the back of a dense pot without soaking the foliage. A can that is nose-heavy when it is full pours in a rush. A rose you can take off is useful. A rose you cannot aim is not.
- A spout long enough for the pots you already own.
- A handle that balances when the can is full.
- A stream that starts and stops, instead of a glug.
- A finish that will not rust where it lives by the sink.
Water the soil. The leaves do not need a shower every time the pot is dry.
A weekly round
Fill it less than you think and make a second trip. A lighter can is easier to aim. Empty it if it will sit. Standing water in the can is how you get a smell and a film.
Buy the spout that reaches your most awkward plant. The pretty metal is secondary.
