Simple care routines to maintain your watering can
Why empty and dry your can
Water left sitting in a watering can creates the conditions for accelerated corrosion, particularly in steel cans. Emptying the can after use and allowing it to dry prevents water from sitting against internal surfaces where it can combine with zinc, paint, or exposed steel.
This is especially important if you've used liquid plant feed. Feed products contain phosphates that significantly accelerate corrosion in steel. After using liquid feed, rinse the inside of the can thoroughly with clean water and allow it to dry completely before storing.
Basic care routine
After each use:
• Empty any remaining water
• Tip the can upside down or at an angle to let water drain from the body, spout, and any crevices
• Leave the can in a position where air can circulate freely — the open spout facing downward or to the side works well
• Allow it to dry before putting it away
If you've used plastic cans with liquid feed, the same rinsing principle applies. While plastic itself is highly tolerant of chemical feeds, rinsing avoids accidental application of residue to plants you didn't intend to treat.
Storage between seasons
When you're not using the can regularly — between growing seasons or during winter — store it in a sheltered location where it won't collect standing water. The simplest option is to keep it upside down or tilted so water cannot accumulate in the base.
Keep the rose (if removable) separate and stored in a dry place. This prevents water from sitting between the rose face and back, which can affect spray performance over time.
Simple is enough
You don't need special products or elaborate routines. Emptying, tipping out excess water, and letting it air dry addresses the fundamental cause of accelerated wear. These simple habits keep your can in good working condition year after year.
