Prof. Charles Hartman, Ph.D.Adequate maintenance of your pruners can safeguard your plants and significantly extend their life. I quickly learned the importance of these two practices after losing an entire rose garden to a disease transmitted through the dirty blades of my pruners. Thorough cleaning after each use can prevent the transfer of pathogens between plants. Sharp blades produce cuts that heal quickly. On the other hand, neglecting to clean the pruners can lead to rust and compromise the pruner's function.
Be sure to clean your pruners after every use without exception. Failing to remove sap and plant residue can attract disease and cause corrosion. I carry isopropyl alcohol wipes in my gardening apron so I can immediately clean them after each use. Be sure to scrub the blades, especially at pivot points, where the debris usually accumulates. Finally, be sure to store your pruners in a dry location, free from moisture or residue, as it can cause rust.
Cleaning Protocol
- Use 70% isopropyl alcohol wipes
- Scrub pivot points with stiff brush
- Dry thoroughly before storage
Sharpening Technique
- Maintain original bevel angle (20-30°)
- Use diamond sharpener for precision
- Hone inner curve with round file
Preventative Care
- Oil pivot points with machine oil
- Store in dry location
- Replace worn springs immediately
- Check blade alignment monthly
Sharpen your blades properly to restore optimal cutting performance. Bypass pruners should be cleaned and maintained monthly during the growing season. Retain the original bevel angle of the blades while sharpening with a diamond sharpener. Anvil pruners need less frequent sharpening and only require professional servicing annually. My tools remain as sharp as a razor when you follow this seasonal schedule.
To keep tools working perfectly, remember to lubricate pivot points regularly. For example, during periods of high use, I apply lightweight machine oil every other week.It becomes extremely critical to swap the springs when tools don't open automatically.As. As a best practice, store pruners in climate-controlled spaces where they won't be exposed to moisture. If you take care of your tools, they can last over a decade.
After cutting out diseased material, ensure that you thoroughly disinfect the area. Soak your blades in a bleach solution for ten minutes, then rinse and dry completely. I used this method to prevent the spread of boxwood blight during an outbreak. If you have consistent maintenance habits, you'll protect your investment season after season.
