How to sanitize pruning shears
Understand that it is important to clean the pruning shears before sanitizing them.
Dirt and small bits of plant matter harbor bacteria and fungi, making it impossible to sanitize the pruning shears thoroughly.
Use a garden hose to wash off the shears.
The hose should be one with a spray nozzle attached to spray the dirt and debris off the pruning shears. Examine the shears closely to make sure they are clean.
