"Maintenance protocols help prolong tool life and keep the plant safe. Disinfect the blades after working on diseased branches using 70% alcohol. These tools should be sharpened once a month during the active seasons with diamond files. Store the tools in a dry place to prevent rust. The rotating points of the tools should be lubricated with machine oil every three months. These methods prevent the transmission of pathogens between plants."
