Clean tools, healthy plants

I think it's important to create good routines around keeping pruning tools clean and sharp - it'll help them last longer, improve their performance and limit the spread of plant diseases and viruses. This is what I do: first clean off dried-on sap and leaf resin with a Niwaki crean mate - a great little scouring block you use like a rubber on the blade. Just wet it a bit first - its so much better than wire wool. Once the metal is clear and smooth, a wipe over with camelia oil will give great protection. Regularly spraying with Citrox disinfectant and wiping with a cloth when using pruning tools during the day will help deter a build up of resin too. For sharpening: I use a whetstone soaked in water using long, full, slow movements down and across the blade always maintaining the same angle. One flat swipe on the back will remove any burrs before wiping off again with camelia oil. I do carry a fine diamond file with me for secateurs to use during the day if needed though I don't use this on shears. Always store tools dry and clean and they'll serve you well for years.
