Gardening tools, like pruning shears, are typically used for working in the soil, slicing through plants, and adding water to the garden and yard. This means that gardening tools are regularly covered in water, damp soil, and sap, which can cause the tools to rust. Protect your pruning shears by spraying them with a lubricating oil, like WD-40. Another important step is to clean and dry your tools before storing them in a safe location.
