No matter how fastidious you are with your plants, there will be a residue of pests and/or diseases in your pots at the end of the season. Many of these come equipped with protective mechanisms that allow them to survive the winter and rise to infect your plants next year. Cleaning everything ready to make a fresh start in spring is time-consuming, but worth the effort.
