Cut away rotten or inedible bits first. Then, clean them off by wiping away dirt and debris or submerging them in water.
It’s essential to clean them properly, but that process varies depending on the type of plant you’re working with.
Break out your dehydrator and arrange the plants a few centimeters apart on the trays. I dehydrate at 110° F for two to three hours, but it’s wise to follow the drying directions on your specific unit.
