An easy way to dry stevia is to cut long stems off the plant and bundle them together with twine.
Then hang these bunches upside down on a herb drying rack in a cool, dark place that is out of direct sunlight.
These leaves will be ready when there is no moisture left.
Sun / Rack Drying
The leaves of the plant can also be individually removed from the stems and spread on a screen outdoors that allows for plenty of air circulation.
After a day or two in the sun drying, the leaves should be ready to store.
Dehydrating
Remove the leaves from the stems and wash and dry them.
Place the leaves on your dehydraters racks, making sure they are not touching.
Use a low setting of around 35˚C to 50˚C (95-120˚F) and dry until there is no moisture left.
Drying in the Oven
Remove the leaves from the stems and wash and dry them.
Place the leaves on lined oven trays, making sure they are not touching.
Dry in the oven that is set at its lowest temperature - or 77˚C (170˚F) - leaving the door slightly ajar. Place a heat-proof spoon in the door if possible.
Make sure to keep an eye of them for any burning or browning.
Condition
After the stevia leaves are dry, condition before storing for up to 12 months.
