The Watering Can is a type of tool in Harvest Moon: Back To Nature. The Watering Can is used for watering your crops and flowers. Your watering can holds 100 units of water and will deplete with each use. It can be upgraded by giving the appropriate ore, along with a fee, to Saibara at the Blacksmith Shop. Every 100% allows a specific upgrade (indicated by a miniature ore icon). Tool upgrade levels are displayed in the tools menu.
